Sierra 18-8042 Marine Fuel Hose Barb Fitting, 1/4 Inch NPT Male Pipe Connector

The Sierra 18-8042 is a male pipe hose barb fitting built for marine fuel line connections. One end has a 1/4 inch NPT male pipe thread that screws into a fuel pump, fuel line fitting, or other threaded port, while the other end is a 1/4 inch (6.35 mm) hose barb that a fuel hose pushes onto and is secured with a hose clamp. The fitting is machined from metal for a durable, corrosion-resistant connection point in the fuel system, with a machined finish. Sierra engineers this hose barb to meet or exceed the performance of the original equipment part it replaces, and Sierra supplies parts like this one to OEM engine manufacturers and boat builders. It is commonly used in outboard fuel line assemblies where a compact, single-piece NPT-to-barb connector is needed to join rigid threaded fittings to flexible fuel hose. The 18-8042 ships as a single piece and is compact at roughly 0.39 x 0.39 x 0.39 inches.
