8AN Male to 8AN 0-ring Port Adapter Clear

The 8AN Male to 8AN 0-ring Port Adapter Clear from REDHORSE PERFORMANCE is a precision-engineered hydraulic fitting designed for high-performance fuel, oil, and coolant systems in motorsports, racing, and custom automotive applications. This straight adapter seamlessly connects two 8 AN male ports, eliminating the need for bulky fittings or compromised flow paths. Users rely on this adapter for fuel systems, transmission cooling lines, and power steering circuits where reliable, leak-free connections are non-negotiable.

Constructed from aerospace-grade aluminum and finished in clear anodize, the 8AN Male to 8AN 0-ring Port Adapter delivers durability while maintaining visibility of internal fluid flow—critical for diagnostics and system monitoring. The 0-ring sealed port design creates a metal-to-metal face seal that prevents pressurized fluid escape even under extreme thermal and mechanical stress. The straight configuration minimizes turbulence and pressure drop, preserving system efficiency and protecting against cavitation in high-RPM environments. At just 0.075 lbs, this compact fitting (2.85 x 1.1 x 3.85 in) integrates seamlessly into tight engine bays and fabricated harnesses.

Professional builders, engine tuners, and race teams select the REDHORSE 920 Series adapter for its consistency and proven leak-free performance across thousands of miles and heat cycles. Compatible with any system using 8 AN male ports—including braided stainless steel hoses, aluminum hard lines, and manifold ports—this adapter functions as a universal interface fitting. Installation requires no special tools; hand-tightening with a wrench backup ensures proper seal without over-torquing. Whether upgrading a fuel distribution block, consolidating multiple hose runs, or retrofitting a custom cooling loop, this fitting delivers reliability that matches factory OEM standards.
