Sierra 18-8108 Marine Fuel Hose Barb Fitting, 3/8 Inch x 3/8 Inch Male

The Sierra 18-8108 is a machined male hose barb fitting sized 3/8 inch by 3/8 inch, built for marine fuel system plumbing where a secure, leak-resistant connection between fuel hose and a threaded fitting or fuel component is required. It has a male connection type with a 3/8 inch (9.53mm) barb on one end and a 3/8 inch (9.53mm) NPT thread on the other, letting it join standard 3/8 inch marine fuel hose to a 3/8 inch NPT port. The barbed end is designed to grip hose securely when paired with the correct hose clamp, resisting slippage and fuel leaks under engine vibration and pressure changes typical of a marine fuel system.

Sierra engineers its marine parts to meet or exceed the performance of the original equipment they replace, and this hose barb is manufactured to the same standard, making it a dependable choice for fuel line repairs, replacements, or new fuel system builds on boats. Its compact size (0.39 x 0.39 x 0.39 inches) and light weight make it easy to fit into tight engine compartments and existing fuel line routing.
