Trident Straight LPG Thru-Fitting for Hose Assemblies – Bulkheads & Decks
Seal your LPG hose assembly where it passes through a bulkhead or deck with this ABYC-compliant straight thru-fitting from Trident. Designed specifically for use with flexible LPG hose assemblies (not copper tubing), it slides over the hose and locks into place to create a vapor-tight, non-abrasive seal — preventing propane fumes from migrating between compartments and protecting the hose from chafe at the penetration point.
Three-piece nylon construction with a lock nut and BUNA-N sealing gland that resists salt water, fuels, weak acids, and common solvents. Rated to withstand up to 70 PSI water pressure across a working temperature range of -22°F to 212°F.

Parts Desk Insights
Best used where a flexible LPG hose assembly exits the propane locker and passes through a bulkhead or deck en route to a galley stove, oven, or cockpit grill. This version is the right choice when you’re running flexible hose rather than rigid copper tubing — and when your bulkhead or deck is up to 1/2″ thick. If you’re running rigid 1/4″–3/8″ copper tubing through a thinner bulkhead (up to 3/8″), see the Trident Straight LPG Thru-Fitting for Copper Tubing instead. For a complete propane system build, pair with the Trident Single 20 lb LPG Cylinder Locker or the Trident Dual 20 lb LPG Cylinder Locker, and browse our full Propane & Accessories range.
