Fitting -6AN to ORB -6AN Flare

The Waterman Racing Comp Fitting -6AN to ORB -6AN Flare (WRC-45303) is a precision adapter engineered for high-performance fuel and coolant system applications where reliable AN line connections are critical. This straight-port, male-to-male fitting transitions from -6AN O-ring boss (ORB) ports to standard -6AN male flare connections, providing the flexibility needed in custom cooling and fuel delivery configurations on race engines, high-output street builds, and specialized motorsports platforms.

Constructed from aluminum and finished in black anodized coating, this adapter offers both lightweight construction and corrosion resistance—essential properties when operating in harsh underhood environments or systems exposed to temperature cycling. The -6AN port size corresponds to tubing with a 3/8-inch outside diameter, a standard specification in performance cooling and fuel system design. The adapter's compact footprint (2.65 x 1.3 x 3.75 inches, weighing just 0.04 lbs) allows seamless integration into tightly packaged engine bays. The ORB connection design with O-ring seal eliminates the need for thread sealant, providing a cleaner interface with superior leak resistance compared to tapered thread connections—a critical advantage in high-vibration race environments where micro-weeping can lead to fluid loss.

This fitting is purpose-built for engine builders and performance technicians who demand precision in system routing and component compatibility. Whether fabricating custom coolant manifolds, integrating aftermarket fuel pressure regulators, or establishing auxiliary cooling circuits, the -6AN to ORB -6AN straight adapter provides the exact port translation needed without compromising flow path integrity or introducing unnecessary pressure drop. Serious motorsports applications require fittings that match the precision of the systems they serve—this adapter delivers exactly that standard.
