A 100 lb propane cylinder holds approximately 23.6 gallons at the correct 80 percent fill level. Cylinders are rated by the weight of propane carried rather than by total volume. The unfilled portion allows the liquid to expand safely with temperature.

This cylinder measures 46.6 inches in height and 15.1 inches in diameter, with a 240 PSI service pressure rating. Empty it is heavy enough that most operations move it with a dolly rather than by hand, and filled it is substantially heavier again. Clearance and floor loading both matter when siting one.

This is a propane and LP cylinder, not an oxygen cylinder. Searches for a “100 lb oxygen tank” describe a different product with a different valve, different pressure rating, and different handling requirements. Propane and oxygen cylinders are never interchangeable.

The POL valve is the standard threaded propane service connection, and the 10 percent designation refers to the fixed liquid level gauge that indicates when the cylinder has reached its correct fill point. That device is what prevents overfilling during a fill by weight or by level. It is a standard specification on cylinders of this size.

The collar is the fixed ring protecting the valve, and it carries the stamped DOT certification markings that a filling facility reads before every fill. It also provides a handling point. A cylinder should never be moved with the valve unprotected.

The 100 lb size serves residential appliance supply where a bulk tank is not installed, commercial cooking, temporary and construction heating, and applications needing longer runs between refills than a 40 or 60 lb cylinder allows. It is normally delivered and exchanged rather than carried to a filling station. Many propane marketers run this size as a route product.

The 100 lb holds roughly 23.6 gallons, against about 14 for a 60 lb and 9.4 for a 40 lb, so it needs far fewer refills. The trade is handling: 40 and 60 lb cylinders can be moved by one person using collar handles, while a 100 lb generally cannot when full. Fittings and propane are identical across all three.

Yes. We supply the full LP cylinder range at wholesale to distributors, propane marketers, and commercial accounts, in pallet and truckload quantities. Request a quote with the size, valve configuration, and quantity.

Yes, they carry DOT and TC approval, so they are accepted by filling facilities in both countries. This matters to distributors operating cross-border territory. Certification documentation is available on request.

Store it upright and secured against tipping, outdoors or in a ventilated space that is not a basement or enclosed living area, with the valve closed and protected by the collar. At this size the mass alone makes a falling cylinder a serious hazard. Local code governs separation distances and quantity limits at a given site.
