10AN STR male Adapter 1/2in NPT Male Clear

The 10AN STR male adapter 1/2in NPT male clear from REDHORSE PERFORMANCE is an essential hydraulic fitting for builders working with aftermarket fuel systems, oil coolers, and brake line conversions. If you're upgrading from factory rubber hoses to braided stainless steel lines, this adapter bridges the gap between AN-sized fittings and standard NPT (National Pipe Thread) ports found on engines, transmissions, and auxiliary components. Whether you're fabricating a custom fuel system or retrofitting cooling lines on a modified motor, this straight adapter eliminates the need for multiple transitions and simplifies plumbing architecture.

Built with precision machining, the 10AN STR male adapter features a male AN connection on one end and a male NPT connection on the other, allowing you to interface braided hose fittings with tapped ports on engine blocks, manifolds, and aftermarket accessories. The clear anodized finish provides corrosion resistance while allowing visual inspection of the fitting interior—a critical feature when troubleshooting flow issues or verifying cleanliness during system assembly. The straight (STR) configuration maintains flow path integrity without angular deflection, reducing turbulence and pressure loss in high-flow applications such as fuel injection systems or track-duty oil cooling setups.

Professionals and enthusiasts restoring or upgrading inline-six, V8, and forced-induction platforms rely on REDHORSE adapters to maintain system integrity during performance modifications. This fitting is compatible with any engine or component featuring a 1/2in NPT female port and works seamlessly with 10AN hose and braided line assemblies. Compact dimensions (2.8 x 1.15 x 3.8 inches) allow installation in tight engine bay configurations, making it ideal for swap applications, turbo upgrades, and custom fuel cell integrations where space is limited. Installation requires standard AN wrench sizes and NPT thread sealant; torque specifications follow industry standard practices for both AN and NPT connections.
