Quick Answer: Does Walmart Sell 100 Lb Propane Tanks?
Yes. Walmart’s online marketplace lists 100-lb propane cylinders, but they generally ship empty. In a listing check on November 9, 2026, a standard Flame King 100-lb steel cylinder was advertised at approximately $274.95, while other listings were higher. These are 2026 listing observations, not confirmed 2027 prices. Local stock, seller, tax and shipping can change what you actually pay.
- Fuel capacity: about 100 lb of propane, or 23.6 gallons
- Example empty-cylinder listing: $274.95, before additional costs
- Refill example: $82.60 at $3.50 per gallon
- First-fill example: about $357.55 for cylinder and fuel
My recommendation: Before ordering, confirm that the listing says 100-lb fuel capacity, check whether the cylinder ships empty, verify the valve type, and arrange a qualified refill or delivery service that accepts this large cylinder.
When I search for a 100 lb propane tank at Walmart, the first number I look at is the online selling price. But I would not base my buying decision on that number alone. A 100-pound propane cylinder is usually sold without fuel. If you need to fill it, have it delivered, connect it to an appliance, or transport it safely, your real first-day expense can be quite a bit higher than the listing price.
That’s why I’ve put together this buyer’s guide. I want to help you understand what Walmart actually lists, how much propane a 100-lb cylinder holds, where you may be able to refill it, and when a larger cylinder can be economical. I’ll use clearly dated examples and original calculations so you can substitute your own local refill quote. This guide is written for U.S. shoppers considering a 2027 purchase, but the price evidence currently available is from November 2026.
100 Lb Propane Tank Walmart Price: What Should You Expect in 2027?
It’s important to distinguish the article’s 2027 planning period from the prices I can verify today. As of November 9, 2026, Walmart’s online category included several 100-lb cylinder options. Some were standard upright steel cylinders with a POL valve, while others offered specialized valves or wheels. There is not one universal Walmart price for every 100-lb propane tank.
| Example Walmart listing | Observed price (Nov. 2026) | What stands out |
|---|---|---|
| Flame King 100-lb empty steel cylinder with POL valve | $274.95 | Standard upright cylinder; advertised empty |
| Worthington Cylinders 100-lb model 303953 | $289.98 | Alternative standard 100-lb listing |
| Flame King 100-lb multi-valve cylinder | $329.95 | Different valve arrangement; confirm refiller compatibility |
| Flame King 100-lb horizontal/vertical wheeled model | $514.95 | Specialized design, wheels and approved orientation features |
I would not assume the $514.95 wheeled cylinder is overpriced simply because its capacity is also 100 lb. Extra mobility features and model-specific engineering affect its cost. But I would not buy those features unless I had a practical need for them. For most stationary outdoor applications, a conventional upright cylinder may be simpler and less expensive.
One more detail matters: a listing can be displayed on Walmart.com without the same item sitting in your neighborhood Walmart store. That’s a big distinction when the cylinder is large and heavy. Online delivery, marketplace fulfillment, and local shelf stock should be treated as separate questions.
100-Lb Propane Tank Specifications and Technical Details
A 100-lb cylinder is named for the approximate mass of propane it is designed to hold, not for the total weight of the steel tank. That can confuse first-time buyers. The empty steel cylinder itself adds substantial weight, and the exact tare weight is stamped on the cylinder. I always tell readers to look at the actual manufacturer’s specification and collar markings rather than assume all 100-pound models are identical.
| Specification | Typical value | Why I check it |
|---|---|---|
| Nominal propane capacity | 100 lb of fuel | Describes the fuel load, not the empty cylinder’s weight |
| Approximate liquid propane volume | 23.6 US gallons | Useful for refill cost calculations |
| Example empty cylinder weight | About 70 lb for a standard Flame King model | Actual tare weight varies by product |
| Example total filled weight | About 170 lb (70 + 100) | Important for handling and delivery planning |
| Example cylinder dimensions | About 14.7 × 14.7 × 50 inches | Check location and clearance requirements |
| Standard valve example | POL connection | Must be compatible with the approved regulator and refiller |
| Approximate fuel energy | 2,159,400 BTU | Allows theoretical runtime estimates |
| Regulatory marking | DOT specification and date markings | Used to assess fill eligibility and requalification |
The example dimensions and empty weight are taken from a standard model specification, not a guarantee for every Walmart listing. A special-purpose cylinder can have a very different base, valve assembly or footprint. I also avoid describing a cylinder’s stamped water capacity as its propane-fill volume. They represent different measurements, and a trained filler determines the permitted fill according to the cylinder and filling rules.
For more background about propane volume and weight, I suggest reading How Much Does 1 Gallon of Propane Weigh?. That explains why weight and gallons are related but are not interchangeable without a conversion assumption.
How Much Does It Cost to Fill a 100 Lb Propane Tank?
A nominal 100-lb propane cylinder holds about 23.6 gallons of liquid propane at a proper full fill. That gives you a convenient way to estimate a refill bill. Your actual charge is based on what the filling station dispenses or its applicable price method, and it can be lower if propane remains in the cylinder. For a wider fuel-cost perspective, see Is Propane Gas Economical?.
For the 2027 planning guide, I use several illustrative per-gallon prices rather than invent a nationwide Walmart refill charge. Walmart’s listings don’t establish that every store can refill a 100-lb cylinder. You should confirm an appropriate refill supplier before buying.
| Assumed propane price | Fuel for 23.6 gallons | What the result means |
|---|---|---|
| $2.50 per gallon | $59.00 | Lower-cost illustrative refill |
| $3.00 per gallon | $70.80 | Moderate-cost illustrative refill |
| $3.50 per gallon | $82.60 | Worked example used below |
| $4.00 per gallon | $94.40 | Higher-cost illustrative refill |
| $5.00 per gallon | $118.00 | Very high-cost illustrative refill |
These figures are fuel-only estimates. They exclude sales tax where applicable, service fees, equipment purchase, transport and delivery charges. Also remember that propane density changes with temperature, and authorized fillers use the required filling method rather than treating 23.6 gallons as a universal instruction for every cylinder.
My Worked Example: Total First-Fill Cost at Walmart
Suppose I choose the standard Flame King 100-lb cylinder listed for $274.95. I find a local qualified propane supplier charging an assumed $3.50 per gallon. To estimate the fuel bill for a nominal full cylinder, I multiply 23.6 gallons by that rate.
Step 2 — Add the tank: $274.95 + $82.60 = $357.55.
Step 3 — Add anything not included: shipping, tax, a compatible regulator, delivery and any professional installation.
Now compare that with a second example: a Worthington 100-lb cylinder at $289.98 under the same assumed propane price. The initial tank-plus-fuel cost becomes $372.58. The $15.03 gap between the two examples is modest compared with the long-term cost of fuel and delivery, so I would choose based on compatibility and seller reliability rather than the advertised price alone.
Here’s a useful insight I haven’t seen explained often enough in basic buying guides: the break-even comparison changes with each refill. The empty cylinder is a one-time acquisition cost, but the propane bill repeats. If you buy a cylinder that a nearby refiller won’t accept, the inconvenience can outweigh a small online discount.
Is a 100 Lb Propane Tank Available at My Local Walmart?
Walmart’s online inventory and local store availability aren’t interchangeable. A 100-lb tank is a bulky specialty item, so it may appear in a general online search without being stocked on the store floor. Some marketplace sellers ship directly to your address, while other listings may show different fulfillment options based on your ZIP code.
If I were shopping today, I would check the product details in this order:
- Exact capacity: confirm the listing says 100-lb propane capacity, not a smaller accessory or a listing for a regulator.
- Actual seller: look at “sold and shipped by” information, including whether it is a third-party seller.
- Available fulfillment: identify shipping, pickup or local delivery, rather than assuming store pickup exists.
- Shipping charges: a less expensive tank plus freight can cost more overall than a higher-priced free-shipping option.
- Valve and certification: check the DOT markings, valve type, and manufacturer specifications.
- Return policy: check who handles returns on an oversized, potentially hazardous-goods-related product.
I would save a screenshot of the offer and its shipping terms before ordering. Prices and stock change, so a dated record is useful if there is a delivery discrepancy. To compare when to purchase fuel, see What Time of Year Is Propane the Cheapest?. My point is not that Walmart is a bad place to look; it’s that a listing price alone doesn’t tell you whether it is the best way to obtain a usable cylinder.
Can Walmart Refill a 100 Lb Propane Tank?
I would not count on a standard Walmart propane exchange cage or a typical store counter for a 100-lb refill. Walmart sells refillable cylinders, but the retailer’s guidance says actual refill services may not be available at every location. Some stores may have exchange programs for particular sizes, which is not equivalent to a refilling service for a 100-lb cylinder.
My preference is to contact a licensed local propane supplier or a qualified refill station that specifically accepts 100-lb cylinders. Ask if the station can fill that size, whether the cylinder’s valve type is supported, and how the cylinder must arrive. If the tank is too heavy to move safely, ask about a delivered or supplier-managed arrangement.
You should never try to fill a 100-lb cylinder from another propane container using improvised equipment. Filling is a trained operation with inspection, weight and safety requirements. I also would not assume every supplier will accept a freshly purchased, independently owned cylinder without first checking the markings and its condition.
How Long Will a 100 Lb Propane Tank Last?
Runtime depends more on fuel input than on the appliance label. I start with the equipment’s input rating in BTU per hour. Then I divide the tank’s estimated total fuel energy—2,159,400 BTU—by that hourly rating. The answer is a theoretical continuous-run estimate, not a guaranteed result.
| Appliance fuel input | Theoretical runtime | Typical planning context |
|---|---|---|
| 10,000 BTU/hr | 216 hours | Small continuous load |
| 20,000 BTU/hr | 108 hours | Moderate appliance demand |
| 30,000 BTU/hr | 72 hours | Multiple or higher-demand uses |
| 40,000 BTU/hr | 54 hours | Large sustained input |
| 50,000 BTU/hr | 43 hours | High-output burner or equipment |
| 80,000 BTU/hr | 27 hours | Very high-demand equipment |
The 50,000-BTU calculation is 2,159,400 ÷ 50,000 = about 43.2 hours. That’s the maximum theoretical runtime at the rated input, assuming the full nominal fuel quantity can be used. If an appliance cycles on and off, calendar time may be longer. If the cylinder can’t vaporize fuel quickly enough, real-world delivery may be limited sooner. For more about this behavior, read Why Does Propane Evaporate Easily?.
I don’t recommend operating until the cylinder is entirely empty, especially for critical heating or backup loads. Planning for a reserve helps you arrange refill or delivery before an interruption. Also remember that a 100-lb cylinder is not automatically appropriate for a home’s entire heating load; system design and local codes should guide the choice.

I use this planning tool to compare your local propane price with the advertised empty-cylinder price. You can also enter your appliance’s BTU rating to estimate continuous runtime. The calculations assume a nominal 23.6-gallon capacity and 91,500 BTU per gallon. The results are illustrative and cannot assess installation, vaporization capacity or safety.
Important: Fill quantities, taxes, delivery and actual burner input vary. This is a budgeting calculator, not a filling instruction or system-sizing approval.
Can You Transport a 100 Lb Propane Tank Yourself?
A full cylinder with approximately 100 lb of propane plus around 70 lb of steel can weigh about 170 lb. I wouldn't treat that as an ordinary item you can casually set in the back seat of a car. Propane cylinders must be transported under applicable rules, secured against tipping or damage, and with their valves protected. The vehicle type and local requirements matter.
For a standard cylinder designed to be used upright, I would keep it upright and secured, as specified by the manufacturer and applicable requirements. Some specialty models are expressly engineered for horizontal and vertical use, but you cannot apply that permission to a different cylinder. Likewise, a wheeled frame does not mean a filled cylinder is safe to transport by any method you choose.
I recommend asking a qualified propane supplier about permitted transport options or delivery before ordering. A store or listing may ship the empty cylinder to you; that is different from transporting it after filling. Never leave a filled cylinder inside a closed vehicle, and never store it inside an occupied building or garage. The low-lying gas hazard is explained in Do Propane Fumes Rise or Fall?.
Are Walmart 100 Lb Propane Tanks Safe to Use?
A propane cylinder sold by a familiar retailer still needs the right certification, current requalification status, compatible connection and safe installation. I would check the cylinder's DOT specification markings, manufacturing date, valve protection, visible condition and manufacturer instructions. A pre-purged cylinder can be ready for a qualified first fill, but that does not mean every local station will accept it without inspection.
In the United States, DOT cylinders require periodic requalification. Federal guidance describes a typical initial period up to 12 years for many propane cylinders, with later intervals varying according to the approved inspection or testing method. Don't rely only on the purchase date: inspect the cylinder's stamped manufacture and requalification markings and let the refiller determine whether it is currently eligible.
Another issue is valve compatibility. The standard Flame King model advertised with a POL valve may not connect directly to the hose supplied with a small grill. I would never recommend an improvised adapter or homemade regulator arrangement. Have a qualified person choose components rated for your exact appliance and supply pressure.
Finally, I wouldn't use a large cylinder in a location that violates clearance or storage rules. Keep it outdoors in a suitable location, upright when required, protected from damage, and away from heat and improper enclosures. The correct solution can vary for a grill, heater, food truck or stationary heating appliance. If you notice a suspicious gas odor, leave and get help; Why Does Propane Smell So Bad? covers odorants and warning signs.
My Decision Guide: Should You Buy a 100 Lb Propane Tank From Walmart?
I use this short guide when deciding whether a larger cylinder makes sense. It is deliberately based on what you plan to do after purchase, because a cylinder without a practical refill and installation plan can become an expensive unused purchase.
| Your situation | My decision | Next step |
|---|---|---|
| You have regular propane use, an approved outdoor location and a nearby 100-lb refiller | Consider buying | Compare delivered total prices and valve compatibility |
| You use propane only for occasional grilling | Compare smaller tanks | Calculate actual refill frequency before spending more |
| Your local supplier doesn't refill customer-owned 100-lb cylinders | Wait | Find another qualified supplier or a delivered cylinder program |
| You cannot move or secure the cylinder safely | Arrange professional handling | Ask about delivery, setup and pickup services |
| You're unsure about the POL valve or regulator | Do not connect it yet | Request advice from a qualified installer |
| Listing price is low but shipping is expensive | Compare total cost | Add shipping, first fill, tax and installation |
My takeaway is that convenience is not just about fewer propane purchases. It also includes how you store the cylinder, whether you can refill it reliably, and whether the installation is suitable for your appliance. You can explore more general usage possibilities in What Is Propane Gas Used For?.
How to Save Money on a Walmart 100 Lb Propane Tank
I would use a practical checklist rather than chase a single headline discount. The exact cheapest choice will change by location, inventory and season, but the comparison method remains useful:
- Compare the same capacity. Don't accidentally compare a 100-lb fuel cylinder with a 100-gallon stationary tank, a 40-lb cylinder or a bare accessory.
- Compare empty-cylinder prices after shipping. Freight can erase an apparent discount.
- Confirm your refiller before buying. A compatible local supply arrangement can matter more than a $10 or $20 purchase difference.
- Check approved valve and regulator compatibility. Buying the wrong setup leads to avoidable additional expenses.
- Use a sensible refill schedule. Running completely out can be inconvenient, particularly for appliances you rely on.
- Think annually, not just today. Estimate how many times you refill and what each trip or delivery costs.
For another planning question, read How to Tell If You Need Propane. I would not rely on time alone to determine the remaining fuel in a cylinder, especially when the appliance's consumption varies.
Frequently Asked Questions About Walmart 100 Lb Propane Tanks
Are Walmart's 100 lb propane tanks prefilled?
The standard models I reviewed were listed as empty, with some described as pre-purged. Never assume propane is included unless the exact listing expressly says so.
How much propane fits in a 100 lb cylinder?
A nominal 100-lb fuel load is approximately 23.6 US liquid gallons, depending on conditions and the authorized filling method.
How much does it cost to refill one?
At an illustrative $3.50 per gallon, 23.6 gallons costs about $82.60 before other fees. Local supplier rates vary.
Can I exchange a 100 lb propane tank at Walmart?
Don't assume a regular 20-lb exchange cage will accept a 100-lb cylinder. Ask the store and a qualified propane supplier about the available service for this size.
How heavy is a full 100 lb propane cylinder?
For an example cylinder with a 70-lb empty weight, the total with 100 lb of propane is about 170 lb. Check the actual stamped tare weight.
My Final Recommendation
If you are searching for a 100 lb propane tank at Walmart in 2027, I recommend starting with a simple distinction: the listed price generally buys the empty metal cylinder, not a full supply of propane. In my November 2026 price check, a standard 100-lb Flame King cylinder appeared around $274.95, while other configurations cost more. Those figures are reference points, not guaranteed future prices.
My preferred buying method is to add the cylinder price, delivery, first fill and any approved connection or installation work. Then I would confirm that a nearby supplier can refill or service that cylinder. If you regularly use propane and have an approved outdoor location, a 100-lb cylinder may reduce your refill frequency. If you only use a small grill occasionally, a smaller cylinder may be much more convenient.
Most importantly, I would not make the purchase until transportation, handling, storage and valve compatibility are resolved. A well-priced cylinder is only a good deal when you can use it safely and refill it reliably.
