#6 Male to 1/2in NPT 90 Deg Ano-Tuff Adapter

The #6 Male to 1/2in NPT 90 Deg Ano-Tuff Adapter from EARLS is a precision-engineered hose fitting designed for high-performance fuel, oil, coolant, and hydraulic line routing in modified and race vehicles. This 90-degree adapter bridges SAE #6 male connections to 1/2-inch NPT female ports, making it essential for custom fuel systems, turbo installations, and engine bay plumbing where space constraints or directional flow changes demand compact, reliable solutions. Whether you're building a fuel-injected swap, integrating an auxiliary cooling circuit, or routing pressurized lines in tight quarters, this adapter provides the directional flexibility that stock configurations cannot offer.

Constructed from anodized aluminum with EARLS' proprietary Ano-Tuff hardening process, this adapter resists corrosion, abrasion, and thermal cycling far better than bare aluminum or mild steel alternatives. The 90-degree elbow design eliminates the need for separate hoses and fittings, reducing assembly time and potential leak points in your fuel or coolant circuit. The SAE #6 male thread (which equals -6 AN, or 3/8-inch OD) mates directly with standard braided hose ends and quick-disconnect couplers, while the 1/2-inch NPT female port accepts metric or imperial manifold ports, carburetors, filters, and regulators. Anodized construction ensures longevity under underhood heat and vibration without sacrificing the light weight critical to performance builds.

Mechanics and fabricators working on street rods, drag racers, and turbocharged platforms rely on EARLS adapters to simplify complex fuel and cooling system layouts where factory mounting points no longer apply. The compact 2.3 × 1.1 × 2.85-inch profile fits in confined engine bays, while the anodized finish matches other EARLS components for a professional appearance. Use this adapter whenever you need to transition from braided -6 AN fuel or oil lines to NPT-threaded manifolds, fuel blocks, or distribution blocks—common in EFI conversions, auxiliary turbo oil coolers, and custom radiator bypass circuits. Always verify NPT thread compatibility with your destination component and use thread sealant appropriate for fuel or coolant service.
