#6 x 3/4-16 (#8) Radius O-Ring Fitting

The #6 x 3/4-16 (#8) Radius O-Ring Fitting is a precision-engineered adapter designed for high-performance fluid transfer systems where reliability is paramount. This straight adapter allows users to bridge connections between different port sizes, specifically converting a -8 AN O-ring boss port to a standard -6 AN male flare. It is an essential component for automotive enthusiasts and professionals building custom fuel, oil, or cooling systems that require secure, leak-proof transitions.

Constructed from high-strength aluminum, this fitting features a blue anodized finish that provides exceptional corrosion resistance and a professional aesthetic. The 3/4-16 thread pitch corresponds to a -8 AN size, while the radius O-ring design ensures a superior seal against the mating surface compared to traditional crush washers. By utilizing a male-to-male configuration, the fitting maintains consistent flow characteristics and minimizes turbulence within the plumbing circuit.

This adapter is ideal for anyone looking to buy specifications-grade hardware for demanding environments where vibration and pressure fluctuations are common. Installation is straightforward, requiring a simple O-ring seat for the 3/4-16 side to achieve a permanent, vibration-resistant seal. Whether you are searching for this specific part for sale for a racing application or a custom build, the #6 x 3/4-16 (#8) Radius O-Ring Fitting delivers the durability needed for long-term service.
