AN Plug -16

The AN Plug -16 from Allstar Performance is a professional-grade hydraulic and pneumatic fitting designed for high-pressure fluid transfer systems in racing, automotive, and industrial applications. This hex head plug serves as a reliable termination point for -16 AN (JIC) port lines, preventing fluid leakage and system contamination. Whether you're assembling a custom fuel system, brake circuit, or cooler line on a competition vehicle, this fitting delivers the durability and precision required in demanding environments.

Constructed from aerospace-grade aluminum and finished with black anodizing, the AN Plug -16 resists corrosion while maintaining a lightweight profile—critical for weight-sensitive racing applications. The anodized coating provides superior protection against oxidation and abrasion, extending service life in both wet and dry environments. The hex head design enables secure installation and removal using standard wrenches, ensuring consistent torque application without stripping. At just 0.13 lbs, this compact fitting integrates seamlessly into tight engine bays and custom plumbing layouts without adding unnecessary mass.

Racers, fabricators, and hydraulic technicians rely on the AN Plug -16 to seal unused -16 AN ports and prevent costly system failures. It pairs perfectly with standard -16 AN hoses, adapters, and valves from OEM and aftermarket suppliers. Installation requires a wrench that fits the hex head—typically 1-1/16 inch—and straightforward insertion into the female AN port. For fuel systems, brake lines, power steering, or cooler circuits, this plug ensures leak-free operation and full system integrity on street, track, and shop applications.
