One end accepts a standard 3\/8\" fuel hose over the barb; the other end threads into any 3\/8\" NPT female port on a fuel tank, fuel pump, or inline fitting. Built to OEM specifications for a reliable, leak-resistant connection in marine fuel systems.\u003c\/p\u003e\u003ch3\u003eBest Use Case\u003c\/h3\u003e\u003cp\u003eUse this fitting when connecting a 3\/8\" flexible fuel hose to a threaded NPT port — common in custom fuel system builds, tank installations, fuel pump connections, and fuel line re-routes where a barb-to-thread transition is needed. The aluminum construction makes it a durable choice for both freshwater and saltwater environments.

The key specs to confirm before ordering are: (1) the hose inner diameter is 3\/8\", and (2) the receiving port is a 3\/8\" NPT female thread. NPT threads are tapered — use thread sealant (PTFE tape or fuel-compatible thread compound) on the male threads when installing to ensure a leak-free seal. Do not overtighten aluminum NPT fittings into steel or cast ports, as the softer aluminum threads can strip.
