Trident 11 lb Transparent Composite Propane Cylinder – Marine & RV
A compact, lightweight propane cylinder that lets you see exactly how much fuel you have left — no gauges, no guessing, no lifting. This 11 lb composite cylinder from Trident is built from high-strength fiberglass with a transparent sidewall so you can check your propane level at a glance, even when the cylinder is locked in a locker or compartment.
Completely rust-proof and maintenance-free, it’s an ideal choice for smaller boats, weekend cruisers, and any application where space and weight savings matter. Manufactured to DOT and TC specifications with an OPD Type 1 valve for safe, compliant use.

Parts Desk Insights
Best suited for smaller boats, day sailors, and compact RV setups where a full 20 lb steel cylinder is too heavy or too large. The 11 lb size is also a practical choice for a dedicated cockpit grill cylinder, keeping your main galley supply separate. If you need more capacity, this cylinder is also available in 17 lb and 22 lb sizes. For a complete propane system, pair with the Trident Single 20 lb LPG Cylinder Locker and browse our full Propane & Accessories range for regulators, hoses, and fittings.
