Fuel Tank Vent Valve with Hose Barb and NPTF Threads

This brass-colored metal vehicle hardware features a hexagonal top, threaded cylindrical body, and side hose barb for a compact, robust fit. As a fuel tank vent valve, it provides a controlled vent path while connecting 1/2 NPTF male mounting threads to compatible systems. Built as a roll-over ball valve, it adds a brass check valve function that helps manage movement through the venting setup. The side barb fits 5/16 in. inner diameter tubing, and the included sealing gasket supports a tighter mounting interface. Dimensions are approximately 54 mm high and 44 mm wide, with a lower diameter of 16 mm and a barb size of 5 mm inner diameter by 9.5 mm outer diameter.
