Fuel Shut-Off Valve, Chromed Brass, Ø8 mm

The fuel shut-off valve (8 mm) is designed to provide a quick and secure way to cut off fuel supply when needed. This small valve installs in the fuel hose between the tank and the engine (or carburetor) and allows the user to stop the flow of fuel – for example, during engine maintenance, fuel filter changes, or when transporting the boat to prevent leaks.

The body of the valve is made of chrome-plated brass, combining the strength of brass with the added protection and smooth finish of chrome. This makes the valve highly resistant to corrosion from fuel (including ethanol-blended gasoline) and saltwater, while also giving it an attractive appearance. The internal mechanism is designed such that when closed it completely blocks the flow, and when open it provides a full bore for fuel to pass through freely.

This model is intended for hoses of about 8 mm inner diameter – a size widely used in the fuel lines of outboard motors and small generators. Installation is straightforward: both ends of the valve have barbed fittings onto which the hoses are pushed. By tightening hose clamps over the connections, a leak-proof seal is ensured. The compact dimensions allow it to fit even into tight spaces around the engine or tank.

• Safe Transport: Close the valve before transporting or tilting the tank/boat to prevent fuel spills or carburetor flooding while moving.
• Maintenance: During fuel filter changes, engine repairs, or winterization, the shut-off valve lets you cut off the fuel flow without needing to drain the entire tank.
• Universal Application: Suitable for gasoline, diesel, and other fuels; can be used on boats, ATVs, generators, and any equipment with ~8 mm fuel lines.
• Longevity: The chromed brass construction won’t rust or seize – the valve will remain easy to open/close even after long periods of use.

Installing this shut-off valve in your fuel line adds an extra layer of safety and convenience, allowing you to control your fuel supply at any time.
