AN To NPT Swivel 90 Deg -6 x 3/8in

The AN to NPT swivel 90 degree -6 x 3/8in adapter from ALLSTAR PERFORMANCE is a precision hydraulic and pneumatic fitting designed for custom fuel, oil, coolant, and brake line installations on high-performance and modified vehicles. This 90-degree swivel connector bridges the gap between AN (Army-Navy) -6 male ports and 3/8-inch NPT (National Pipe Thread) male ports, making it essential for engine builders, fuel system upgrades, and custom plumbing applications where space constraints or angle requirements demand a compact solution.

Constructed from aluminum and finished in black anodize, this swivel fitting eliminates the need for separate adapters and elbows, reducing connection points and potential leak sources in critical systems. The swivel design allows hose routing flexibility without stressing fittings or crimped AN hose ends, protecting both the hose barb and the fitting threads from mechanical stress during vibration or thermal cycling. The 90-degree geometry is particularly valuable in tight engine bays where straight connectors would interfere with manifolds, heads, or accessory mounting, while the -6 AN designation (3/4-inch hose ID equivalent) handles substantial flow rates required by fuel injection systems, turbocharger coolers, and remote reservoir setups on turbocharged or supercharged platforms.

This adapter is ideal for fabricators routing fuel lines through confined spaces, custom cooling system builders interfacing modern fuel rails with vintage manifold ports, and shop technicians adapting OEM NPT gauge ports to AN quick-disconnect couplers. The compact 2.55-inch length and lightweight aluminum construction (0.07 lbs) make installation straightforward without adding bulk to engine bay plumbing. Compatibility extends to any system combining AN -6 hose barbs or male connectors with 3/8-inch NPT female threaded ports—verify thread type and hose size before ordering to ensure proper sealing and flow capacity for your specific application.
