#10 O-Ring Port Plug w/1/8in NPT in Center

The #10 O-Ring Port Plug with 1/8" NPT Center Port from Magnaflow Fuel Systems is a precision fuel system fitting designed to seal high-pressure fuel rail ports while maintaining access for instrumentation or future expansion. This aluminum plug features a #10 AN O-ring seal and integrates a 1/8-inch NPT female port at its center, making it ideal for fuel system tuning, pressure monitoring, or auxiliary component integration in performance fuel systems.

Built from aluminum construction with a purple anodized finish, the MP-3073 delivers both durability and corrosion resistance in demanding engine bay environments. The hex head design provides secure installation and removal using standard wrenches, while the O-ring port seal ensures leak-free operation under fuel pressure. The 1/8-inch NPT center port allows for gauge installation, sensor mounting, or secondary line connection without disrupting the primary fuel rail system. This compact fitting (3.05 x 0.8 x 3.75 inches) weighs just 0.05 lbs and integrates seamlessly into existing fuel rail configurations.

Buyers installing custom fuel systems, performance engine builds, or multi-stage fuel injection setups rely on these plugs to maintain system integrity while accommodating future modifications. The #10 AN O-ring port standard ensures compatibility with OEM and aftermarket fuel system components. Whether sealing unused ports on high-flow fuel rails or providing a mounting point for pressure sensors and diagnostic equipment, this fitting provides the precision interface demanded by serious fuel system development and tuning applications.

Magnaflow Fuel Systems specializes in engineered fuel delivery solutions for performance and racing applications, where system reliability and component compatibility are non-negotiable. The anodized aluminum construction and O-ring seal design represent the durability standard expected in professional fuel system work.
