Trident Straight LPG Thru-Fitting for Bulkheads & Decks
Route your boat’s LPG supply line cleanly and safely through bulkheads and decks with this ABYC-compliant straight thru-fitting from Trident. It creates a vapor-tight, non-abrasive seal around the copper tubing as it passes through the structure — keeping fumes from migrating between compartments and protecting the line 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 and working temperatures from -22°F to 212°F.

- Fits 1/4″ to 3/8″ LPG copper tubing (installed before flare nuts are attached)

- 3-piece nylon construction with lock nut and BUNA-N sealing gland
- Rated to 70 PSI water pressure
- Working temperature range: -22°F to 212°F

Parts Desk Insights
Best used wherever an LPG copper supply line exits the propane locker and passes through a bulkhead or deck on its way to a galley stove, oven, or cockpit grill. Required for any ABYC-compliant installation — the fitting prevents vapor from traveling along the outside of the tubing into living spaces. Install before attaching flare nuts to the copper line. If you’re running a complete propane system, pair this 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 for regulators, hoses, and control components.
