6AN to 6AN O-Ring Port Adapter Clear Male Male

The REDHORSE PERFORMANCE 6AN to 6AN O-Ring Port Adapter Clear Male Male (model 920-06-06-5) is a precision hydraulic and fuel system fitting designed for high-performance engine builds, race vehicles, and custom fluid routing applications. This straight adapter bridges two 6 AN male connections, enabling seamless integration in fuel injection systems, coolant lines, and pressurized fluid circuits where vibration resistance and leak-free performance are non-negotiable. Professionals and enthusiasts rely on this adapter to consolidate connection points and optimize plumbing layouts in tight engine bays.

Manufactured from aluminum and finished with natural anodizing, this 920 Series fitting delivers lightweight durability without sacrificing strength or corrosion resistance. The O-ring port design creates a positive seal at both ends, eliminating the need for thread sealant and reducing assembly time. The clear anodize finish allows visual inspection of the aluminum substrate while providing a protective oxide layer that resists oxidation in engine compartment environments. At just 0.06 lbs and measuring 2.85 x 1.1 x 3.75 inches, the adapter installs in confined spaces while maintaining full flow capacity across both 6 AN ports.

This adapter suits custom fuel systems, turbo coolant circuits, transmission cooler lines, and any application requiring a straight male-to-male 6 AN connection. The O-ring sealing method is compatible with standard AN hose fittings and port connections rated for 6 AN specifications. Installation is straightforward—no special tools are required beyond a wrench for the hex body. Whether building a street engine, race car, or off-road vehicle, this REDHORSE fitting integrates seamlessly into existing 6 AN plumbing networks and supports pressures common to modern performance fuel and cooling systems.
