AN Plug -6

The Allstar Performance AN Plug -6 is a hex-head aluminum fitting designed for high-performance fuel, oil, and coolant system applications where precision AN (Army-Navy) threaded connections are critical. This compact adapter serves as a dead-end closure or manifold block-off for -6 AN ported systems, making it essential for custom fuel injection setups and bypass line terminations.

Constructed from aluminum alloy, the AN Plug -6 features the standard -6 AN thread specification (3/8-24 UNF), which accommodates hose barb fittings and JIC adapters common in fuel and coolant circuits. The hex-head design allows socket or wrench engagement without marring the fitting body, critical when working in tight engine bay confines where line-wrenching isn't feasible.

At just 0.03 lbs and measuring 2.05 x 0.85 x 3.95 inches, this fitting integrates seamlessly into compact fuel cell plumbing and tight manifold block configurations typical of street rods, race cars, and heavily modified engines. Mechanics and fabricators will appreciate the reliability and clean, leak-free sealing this fitting provides during automotive modifications.
