If you need a propane tank with roughly 5 gallons of capacity, none of these five listings is a true 5-gallon tank. The products range from a 5-pound cylinder holding about 1.25 gallons to a 20-pound cylinder. The Flame King 20-pound tank is the closest listed option by capacity; the 5-pound tank with a gauge is better for buyers who want to monitor fuel level, while the Gas Hauler Kit suits campers who want a tank and carrying case together.
| Product | Listed Capacity | Best For |
|---|---|---|
| Flame King 20-Pound Cylinder | 20 pounds; gallons not specified | Buyers wanting the largest listed cylinder |
| Flame King 10-Pound Cylinder | 10 pounds; gallons not specified | Portable outdoor use |
| Flame King 5-Pound Tank With Gauge | 1.25 gallons | Checking fuel level |
| Flame King 5-Pound Tank | 1.25 gallons | A basic refillable small tank |
| Flame King Gas Hauler Kit | 5-pound tank, about 1.2 gallons | Transporting a tank for outdoor trips |
Flame King 20-Pound Steel Propane Cylinder
Best for: Buyers who want the largest listed cylinder and do not require an exact 5-gallon capacity. The listing identifies it as a 20-pound steel tank, making it the biggest by stated weight among these options.
Its features include welded steel construction, a powder-coated exterior, and a Type 1 OPD valve assembly. The product information also states that it is DOT approved and X-ray and hydrostatic tested. These details make it a practical comparison point for buyers prioritizing a larger cylinder with listed testing and valve features.
Limitation: The supplied product details do not state its gallon capacity, so do not assume it holds 5 gallons. Confirm the capacity and appliance connection requirements before buying.
Flame King 10-Pound Steel Propane Tank
Best for: Buyers who want a smaller cylinder than the 20-pound model for camping, fire pits, heaters, grills, or overlanding. The product listing specifically describes these outdoor uses.
The tank has welded steel construction, a powder-coated exterior, and an OPD valve assembly. The listing also states that it is DOT approved and X-ray and hydrostatic tested. Choose this model if the 20-pound tank is more capacity than you want to carry but a 5-pound tank seems too small.
Limitation: The product details state its weight capacity, not its gallon capacity. It is not described as a 5-gallon tank.
Flame King 5-Pound Tank With Gauge
Best for: Buyers who prefer a compact tank with a built-in way to check the fuel level. Its listed capacity is 1.25 gallons, so it is suitable when a small cylinder matters more than reaching a 5-gallon target.
The tank is supplied empty and pre-purged, ready for propane filling. It uses welded steel with a powder-coated finish and includes an OPD valve. The built-in gauge is the main difference from the other 5-pound cylinder in this group.
Limitation: At 1.25 gallons, this tank is substantially smaller than a 5-gallon tank. The gauge is a level-reading feature, not additional fuel capacity.
Flame King 5-Pound Tank With OPD Valve
Best for: Buyers who want a straightforward small refillable cylinder without the built-in gauge feature. Its 1.25-gallon capacity is specified in the product details.
This empty, pre-purged tank is made from welded steel with a powder-coated finish. It has an OPD valve, and the listing states that it is X-ray and hydrostatic tested and certified to DOT and Transport Canada requirements. It may suit users who value those stated details in a compact tank.
Limitation: It holds about one quarter of the target 5 gallons. It does not include the gauge identified on the other 5-pound model.
Flame King Gas Hauler Kit
Best for: Campers and other outdoor users who want a small tank bundled with carrying accessories. The kit includes a 5-pound refillable tank, an adapter hose, and an insulated protective case.
The case has safety vent holes and room for the hose and other accessories. The listing describes the kit for activities such as camping, boating, fishing, RVing, and tailgating. Choose it over a standalone 5-pound tank if a dedicated carrying case and included hose are useful for your trip.
Limitation: The tank is listed at about 1.2 gallons, not 5 gallons. The carrying case does not change the amount of propane the tank holds.
Buying Guide: How to Choose a Propane Tank
Do you need exactly 5 gallons?
Check the tank’s stated capacity before purchasing. These listings include 5-pound, 10-pound, and 20-pound cylinders, but none is identified as a 5-gallon tank. A 5-pound cylinder is listed at approximately 1.2 to 1.25 gallons. For a specific gallon requirement, look for a product that states gallon capacity directly rather than relying only on its pound rating.
Should you choose a bigger tank or a portable one?
The 20-pound cylinder is the largest listed by weight, while the 10-pound model offers a middle option. The 5-pound models prioritize compact size. Consider how much propane your appliance uses, how often you can refill the tank, and how you plan to transport it. The provided details do not establish runtime for any particular appliance.
Which features matter?
- OPD valve: Several listings identify an overfill prevention device.
- Fuel gauge: The 5-pound gauge model offers a listed way to check the fuel level.
- Carrying accessories: The Gas Hauler Kit bundles a case and adapter hose.
- Construction and testing: Compare each listing’s stated steel construction, finish, and testing information.
Before filling or connecting a tank, verify that its valve and connection match your intended equipment and follow the manufacturer’s instructions. Do not infer compatibility from tank size alone.
