#8 X 7/8-14 (#10) Radius O-Ring Fitting

The #8 X 7/8-14 (#10) Radius O-Ring Fitting by FRAGOLA is a precision hydraulic and fuel line adapter engineered for high-performance fluid transfer systems. This straight adapter connects AN male ports with different sizing standards—specifically matching #8 AN male to #10 AN male configurations—making it essential for custom fuel systems, hydraulic circuits, and performance engine builds where port mismatches demand reliable solutions. The blue anodized aluminum construction provides both corrosion resistance and visual identification on the working line.

Built with FRAGOLA's signature radius O-ring design, this fitting employs elastomeric sealing technology that distributes clamping pressure evenly across the O-ring surface, reducing stress concentration and preventing fluid leakage at operating pressures. The straight-through geometry ensures minimal turbulence and pressure drop, critical for fuel delivery systems and brake circuits where flow efficiency directly impacts performance. Aluminum construction keeps weight minimal while maintaining structural integrity—a key advantage in racing, aerospace, and weight-sensitive applications where every fraction of a pound matters.

This adapter suits custom fuel system designers, high-performance engine builders, and hydraulic system technicians who require precise port adaptation without compromising flow dynamics. Installation is straightforward using standard AN wrench sizes, and the blue anodized finish aids quick visual verification during assembly and maintenance. Ideal for turbocharged platforms, nitrous oxide systems, and professional racing applications where system reliability and proven sealing performance are non-negotiable.
