AN to O-Ring -8 x 3/4-16 (-8)

The AN to O-Ring -8 x 3/4-16 (-8) adapter from Triple X Race Components is a straight-port hydraulic and fuel line fitting designed to connect two -8 AN (Army-Navy) male ports with integrated O-ring sealing. This fitting serves as a critical interface in high-performance racing, marine, and automotive hydraulic systems where precision connections and leak-free operation are non-negotiable. Whether you're building a custom fuel system, brake line manifold, or oil cooler circuit, this adapter ensures secure, vibration-resistant connections under demanding conditions.

Manufactured from aluminum and finished in black anodize, the AN to O-Ring -8 x 3/4-16 (-8) combines lightweight durability with corrosion resistance. The O-ring face seal design eliminates the need for additional PTFE tape or sealant compounds, relying instead on a resilient elastomer O-ring compressed between mating faces to create a metal-to-metal sealed connection. The 3/4-16 thread specification provides the standard port size for -8 AN applications, ensuring compatibility with industry-standard manifolds, adapters, and components. Black anodizing protects the aluminum from oxidation and provides a professional, race-ready appearance while maintaining excellent thermal properties.

Ideal for fabricators, race teams, and performance enthusiasts, this fitting performs reliably in fuel injection systems, turbo oil supply lines, transmission cooler circuits, and custom hydraulic applications. Installation is straightforward: thread the fitting into the receiving port until hand-tight, then apply a final wrench turn to seat the O-ring seal without over-torquing. The compact 1 x 1 x 1.5-inch footprint minimizes installation space while the lightweight 0.04-pound design integrates seamlessly into weight-critical applications. Compatible with any -8 AN male threaded port, this adapter is an essential component for anyone assembling modular hydraulic or fuel systems where reliability and cleanliness are paramount.
