Propane

Yes, a 30 lb propane tank is one of the standard removable cylinder sizes used on RVs, travel trailers, and campers. Its OPD valve and standard propane connection fit typical RV regulators and tank trays. Confirm your RV uses removable DOT cylinders rather than a built-in ASME tank, and that a 30 lb upright tank fits your mounting bracket.

The main difference is capacity and run time: a 30 lb tank holds about 7 gallons of propane versus roughly 4.7 gallons in a 20 lb tank. The 30 lb size is taller and heavier but needs fewer refills, which suits RVs, larger heaters, and longer trips. Both use the same OPD valve and standard connection, so accessories are interchangeable.

No, a 30 lb propane tank is not a 30 gallon tank, though the two terms are often mixed up. A 30 lb tank actually holds about 7 gallons of propane, because propane is measured by weight rather than tank volume. If you searched for a “30 gallon propane tank,” a standard 30 lb cylinder like this one is usually what you want.

A 30 lb propane tank holds about 7 gallons of propane when filled to the safe level, since propane weighs roughly 4.2 pounds per gallon. On an RV furnace or a patio heater it can run for many hours, though a large heater used continuously draws it down faster. Actual run time depends on your appliance’s BTU rating.

A recertified propane tank is a used steel cylinder that has been inspected, requalified to DOT standards, refinished, and fitted with a new OPD valve before sale. Reconditioning brings it back to reliable service at a lower price than a new tank. Each cylinder is pressure-checked and repainted, so it performs like new.

Yes, this is a refillable 30 lb propane tank, so you can have it filled at any propane refill station instead of swapping it at an exchange cage. Refilling usually costs less per pound than exchange and lets you keep the same tank. The new OPD valve is required for filling and stops automatically at the safe level.

OPD stands for Overfill Prevention Device, a valve required on modern propane tanks that stops the fill at a safe level. This tank comes with a new OPD valve, so any refill station will fill it without issue. Older tanks lacking an OPD valve can no longer be legally refilled.

A 30 lb propane tank stands about 23 inches tall and 12.3 inches in diameter, taller than a 20 lb tank but a similar footprint. Check the height clearance in your RV tank tray, grill cabinet, or storage area before buying. Its carry-collar handles make it easier to lift and position.

No, this tank ships empty for transport safety and does not include a gauge. Have it filled at a local propane station or exchange, and add a clip-on or inline propane gauge separately if you want to track the level. Shipping empty is a legal requirement for propane cylinders.

Yes, this recertified tank is DOT approved and requalified before sale, so it meets the same safety standards as a new cylinder. Each tank is inspected, fitted with a new OPD valve, and pressure-checked during reconditioning. Refill stations read the collar stamp and fill it like any compliant tank.
