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

The #8 x 7/8-14 (#10) Radius O-Ring Fitting Black from FRAGOLA is a precision hydraulic adapter designed for specific applications in fuel, oil, and coolant systems. It is particularly suited for use in modified vehicles and race applications, providing reliable, leak-free connections that performance mechanics require. This fitting is essential for those working on forced induction systems and custom cooling loops.

Constructed with FRAGOLA's radius o-ring design, this #8 AN fitting features a 7/8-14 thread specification that enhances sealing geometry compared to standard straight-thread adapters. The black anodized finish offers corrosion resistance, while the precision-machined aluminum body ensures durability under high-pressure conditions. The radius o-ring profile allows for a dual-sealing interface, accommodating minor surface irregularities and extending the lifespan of the fitting.

This fitting is ideal for custom fuel rail fabrication, turbo feed-and-return line assembly, and other applications where OEM routing is impractical. Mechanics and fabricators involved in LS swaps and similar projects will find this fitting invaluable for maintaining consistent pressure and reliability in their systems.
