Trident 5-Gallon Aluminum LPG Tank – Marine & RV
A high-capacity, permanently rust-free propane tank built for the demands of marine and RV use. This 5-gallon aluminum LPG tank from Trident is machined from high-strength aluminum that won’t corrode, pit, or rust — ever. Lighter than steel and built to last in salt air and wet environments, it’s a reliable long-term solution for boats and RVs that need a larger onboard propane supply.
Dimensions are approximate — verify clearances and mounting space before installation.
Features
- High-strength aluminum construction — corrosion-free and rust-free for life
- 5-gallon (approximately 20 lb) LPG capacity
- Lighter than equivalent steel tanks
- Designed for marine and RV propane systems
- Dimensions are approximate — confirm fit before installation
Parts Desk Insights
Best suited for cruising sailboats, larger powerboats, and RVs where a higher-capacity propane supply is needed for extended use of galley stoves, ovens, heaters, or cockpit grills. The aluminum construction makes it a smart long-term investment over steel — no rust, no repainting, and no degradation from salt air exposure. If you’re building out a complete propane system, pair this tank with a Trident Marine LPG Regulator, LPG Pigtail Hose, and the appropriate LPG Thru-Fitting for your bulkhead. For portable or smaller-capacity needs, see our 17 lb and 22 lb Transparent Composite Cylinders. Browse the full Propane & Accessories range for all system components.
