Fitting -8an ORB x 8an Flare

The Fitting -8AN ORB x 8AN Flare from Waterman Racing Components is a precision hydraulic and fuel system adapter engineered for high-performance racing and motorsport applications. This straight adapter connects an 8 AN male O-ring boss (ORB) port to an 8 AN male flare port, making it essential for custom fuel lines, cooling circuits, and power steering systems where port types differ. Built for builders and technicians who demand reliability under extreme operating conditions, this fitting eliminates the need for bulky converter blocks and reduces system complexity.

Constructed from aluminum and finished in durable black anodizing, this adapter resists corrosion and oxidation while maintaining a lightweight profile critical in racing applications. The ORB end features a captive O-ring design that creates a dynamic seal, eliminating the need for traditional flange hardware and reducing potential leak points. The flare end accepts standard 8 AN flare fittings with proven JIC geometry, ensuring compatibility across manufacturers. At just 0.06 lbs, this fitting adds minimal weight while delivering maximum sealing integrity under pressure cycling and thermal stress typical in engine bays and fuel cell installations.

This adapter serves drag racers, road course competitors, and custom fabricators building bespoke cooling and fuel systems. It is particularly valuable when connecting ORB-equipped components (such as water blocks, thermostats, or fuel regulators) to flare-based distribution lines without requiring costly porting modifications. Installation is straightforward—thread the O-ring boss fitting hand-tight plus one-quarter turn, and torque the flare nut to manufacturer specifications. The straight design eliminates flow turbulence, making it ideal for high-flow cooling circuits where pressure drop directly impacts performance.
