Automatic Gas Safety Shut-Off for Your Boat – 3/8" Line
Keep your onboard LPG system safe and under control with this 3/8" brass solenoid shut-off valve. Designed for low-pressure propane and LPG lines, this valve stays closed by default — it only opens when 12V power is applied, and automatically shuts off the moment power is cut or lost. That means if your engine stops, your bilge alarm triggers, or you simply flip a switch at the helm, the gas line closes instantly.
The 3/8" port size makes this valve the right choice for higher-flow LPG installations — such as larger galley stoves, onboard heating systems, or any setup where a 1/4" valve would restrict flow. Also available in a 1/4" version for smaller or standard installations.
Key Features
- Fail-safe design: closes automatically with no or low electrical current — gas cannot flow without active 12V power
- Will not open under high pressure — prevents accidental activation
- 3/8" port size for higher-flow LPG applications
- Brass body construction for corrosion resistance in marine environments
- CE certified for safety compliance
- Draws 790 mA at 12V DC
- Includes 2 brass compression fittings for straightforward installation
Parts Desk Insights
The 3/8" port size is the key differentiator here — choose this valve when your LPG line is 3/8" diameter, or when you're running a higher-demand appliance like a larger range or a cabin heater where a 1/4" valve would create a flow restriction. Like the 1/4" model, this valve is most commonly wired to a helm-mounted switch or a gas alarm controller that automatically cuts power if combustible gas is detected in the bilge. Contact our parts desk if you need help confirming the right port size or selecting compatible hose and fittings for your installation.
