Set of Aluminum Fuel Filter Connectors (10 mm Hose)

This set includes two high-quality aluminum connectors designed for fuel filters and separators used in boats and other vehicles. These connectors (also known as hose barbs or couplings) attach the fuel hose to the inlet/outlet of the filter head. With a hose barb sized for 10 mm inner diameter fuel lines, they are ideal for high-flow systems or standard fuel lines on powerful engines that use 3/8" hoses. The threaded end of each connector is a standard 3/8" size (NPT/UNF**)**, ensuring compatibility with most universal fuel separators and filters on the market, including the 01836-1 model and similar units. Made from aluminum, the connectors are lightweight yet exceptionally strong. Their surface is anodized to resist corrosion from gasoline, diesel, or saltwater, ensuring a long service life. By using these, you can replace factory plastic fittings (which may crack or leak over time) with reliable metal ones. Installation is straightforward: unscrew the old connector from your filter, thread in the new one using appropriate sealant (Teflon tape is recommended), and attach your fuel hose to the barb with a clamp. The result is a secure, tight connection that prevents fuel leaks and air ingress into the fuel system.

• Application: This connector set is compatible with many fuel filter and separator models – for example, the transparent water separator (code 01836-1) or standard Racor/Sierra-type filter heads commonly used in marine engines. It works for both gasoline and diesel fuel systems. It’s especially useful for vessels where vibrations and a harsh saltwater environment can compromise plastic fittings. With these aluminum connectors, you gain peace of mind that your fuel line connections are robust. After installation, it’s advisable to check for leaks while the engine is running and periodically inspect the connectors for any loosening (particularly after long voyages or heavy vibration).
