One end accepts a standard 3\/8\" fuel hose over the barb; the other end threads into any 1\/8\" NPT female port on a fuel system component. The brass construction delivers corrosion resistance and durability in marine fuel environments, and the OEM-specification build ensures a reliable, leak-resistant connection.\u003c\/p\u003e\u003ch3\u003eBest Use Case\u003c\/h3\u003e\u003cp\u003eUse this fitting when a 3\/8\" fuel hose needs to connect to a small 1\/8\" NPT-threaded port — common in primer bulb connections, fuel gauge tap points, small-bore fuel system fittings, and custom fuel line builds where a barb-to-small-thread transition is required. The 1\/8\" NPT thread is a standard size for many marine fuel system accessories.
