Trident Hose Liquid Propane Gas (LPG) Fuel Feed Line
Trident Hose LPG Fuel Feed Lines: Marine-Grade Propane Delivery You Can Trust
When it comes to routing liquid propane gas safely aboard a vessel, the integrity of every connection in the system matters. Trident Hose has been one of North America's most respected marine hose manufacturers since 1985, and their LPG fuel feed line products reflect decades of engineering experience in demanding marine environments. As the oldest North American marine hose company under the same ownership, Trident brings a level of institutional knowledge to LPG hose design that few competitors can match.
Built to High-Pressure Marine Standards
Trident's LPG supply line hoses are engineered specifically for the high-pressure demands of propane gas systems on boats. The hoses are constructed from high-pressure thermoplastic — a material chosen for its flexibility, corrosion resistance, and durability under the stress and vibration typical of marine use. Each hose assembly is fully assembled and leak-tested before it leaves the factory, giving installers and boaters confidence that the line is ready to perform safely right out of the box.
Fittings on Trident's LPG supply line hoses are machined from solid brass, providing a secure, corrosion-resistant interface with propane regulators and appliances. Standard configurations use 3/8" female swivel flare fittings on each end, making integration with existing onboard LPG systems straightforward. Working pressure is rated at 350 psi — well above the operating pressures typical of marine propane systems — providing an important safety margin for on-the-water use.
UL Listing and ABYC Compliance
One of the most important differentiators for Trident's LPG fuel feed lines is their UL listing. This certification means the hose has been independently evaluated and meets recognized safety standards for liquid propane gas applications. Trident's broader LPG product ecosystem — including regulators, lockers, and detection systems — is designed to meet ABYC (American Boat and Yacht Council) marine standards, the benchmark for safe marine propane system design in North America. Choosing a UL-listed, ABYC-compliant hose is not just best practice; it is often required for insurance purposes and compliance with USCG guidelines.
Why the Feed Line Is the Critical Link
An LPG fuel feed line serves as the artery of a boat's propane system, carrying gas from the storage cylinder — typically housed in a dedicated deck locker — to the regulator and downstream to cooktops, grills, or heating appliances. In a marine environment, that hose must withstand UV exposure, saltwater spray, constant vibration, and temperature swings that would quickly degrade inferior materials. Trident's thermoplastic construction addresses each of these challenges, offering flexibility without the fatigue cracking risks associated with rigid copper tubing runs in high-vibration installations.
Available in multiple lengths, Trident's LPG supply line hoses accommodate a range of installation configurations — from compact day-sailer galleys to larger trawler and sportfish layouts where the propane locker may be located some distance from the cooking appliance. Whether you are replacing an aging hose or fitting out a new galley installation, Trident's LPG fuel feed lines are a proven, standards-compliant choice for safe propane delivery aboard your vessel.
