ABYC-Compliant LPG Leak Test Adapter for Marine Gas Systems
Pressure-testing your onboard LPG system is a required safety check under ABYC marine standards — and this adapter makes it straightforward. Install it between your LPG cylinder valve and your regulator or pigtail hose (on systems without a built-in gauge) to perform a proper leak test without any additional tools or assembly.
Everything you need arrives fully assembled and pre-tested: a solid brass male POL cylinder fitting, a female POL receptacle block, and a 300 PSI gauge that's low-profile, watertight, and stainless steel — built to handle the marine environment.

Parts Desk Insights
This adapter is the go-to solution for boats that have a standard two-stage LPG regulator without an integrated pressure gauge. It's most commonly used during annual safety inspections or when commissioning a new LPG installation to confirm there are no leaks in the system before lighting the stove. If your regulator already has a built-in gauge port, you may not need this adapter — contact our parts desk and we can confirm compatibility with your setup.
