10AN to 8AN O-Ring Port Adapter Black Male Male

The 10AN to 8AN O-Ring Port Adapter Black Male Male (model 920-10-08-2) from REDHORSE PERFORMANCE is a straight-port hydraulic fitting designed for fluid transfer systems requiring a reliable step-down connection. This adapter is essential for custom fuel, coolant, and brake line installations where port sizes must transition from a larger 10 AN male connection to a smaller 8 AN male outlet. Built for high-performance racing, off-road, and custom automotive applications, this fitting ensures leak-free operation under demanding conditions.

Constructed from aluminum and finished in black anodized coating, the 10AN to 8AN O-Ring Port Adapter provides superior corrosion resistance and a professional appearance in engine bays and custom builds. The integrated O-ring design eliminates the need for separate seals, creating a compact and secure connection that withstands vibration and thermal cycling. The straight-port geometry allows for efficient fluid flow while the male-to-male configuration enables flexible plumbing layouts in confined spaces. Anodized aluminum construction balances weight savings with durability, making it ideal for performance applications where every ounce matters.

This adapter serves motorsports enthusiasts, custom fabricators, and performance shops building fuel systems, cooling circuits, and brake lines on high-horsepower vehicles. The O-ring port configuration is compatible with standard AN fittings used across most performance hydraulic systems, ensuring straightforward integration into existing line assemblies. Installation requires hand-tightening onto compatible 10 AN and 8 AN ports, with proper torque application preventing over-tightening and seal damage. Whether upgrading a turbo fuel system or rerouting coolant on a race car, this fitting delivers the reliability demanded in competitive and street performance environments.
