Straight Adapter Fitting #8 x 1/2 MPT

The Straight Adapter Fitting #8 x 1/2 MPT is a precision hydraulic and pneumatic line connector designed to bridge AN (Army-Navy) 8-sized ports to standard 1/2-inch NPT (National Pipe Thread) male connections. Built by FRAGOLA, a trusted name in fluid power adapters, this fitting serves technicians, mechanics, and engineers who need reliable transitions between different thread standards on fuel systems, brake lines, coolant circuits, and air systems. Whether you're upgrading a classic engine bay, fabricating a custom fuel delivery system, or repairing industrial equipment, this adapter provides the compatibility layer your project demands.

Constructed from lightweight aluminum and finished in blue anodize for corrosion resistance, the Straight Adapter Fitting #8 x 1/2 MPT maintains structural integrity while resisting oxidation in harsh environments. The straight configuration ensures zero-angle flow path, minimizing turbulence and pressure drop—critical for fuel injection systems and high-flow applications. The male-to-male design (8 AN male on one end, 1/2 NPT male on the other) allows this adapter to thread directly into female NPT ports or adapter blocks without additional fittings, streamlining assembly and reducing leak points. The compact footprint (4.15 inches in length) fits tight engine compartments and fabrication spaces where space is at a premium.

This adapter is ideal for custom fuel system builds, cooling system conversions, and pneumatic tool line installations where AN and NPT standards must coexist. Installers benefit from the durable aluminum construction, which resists vibration-induced loosening and won't corrode under hood heat or outdoor storage. Use with compatible -8 AN hoses and fittings on one side and standard NPT-threaded ports on the other; always verify thread pitch and port size before installation. At just 0.05 lbs, it adds negligible weight while delivering years of leak-free service when properly torqued and sealed with appropriate thread sealant.
