Inlet Fitting -8 O-Ring To -10an

The Inlet Fitting -8 O-Ring To -10AN from Waterman Racing Comp. (WRC-45307) is a precision-engineered adapter designed for high-flow hydraulic and fluid transfer applications in performance racing and competitive motorsports environments. This straight-through fitting converts an 8 AN male o-ring inlet to a 10 AN male outlet, enabling seamless integration between incompatible line sizes in fuel systems, cooling circuits, and power steering setups where space and flow optimization are critical.

Constructed from aluminum and finished in black anodized coating, this fitting delivers corrosion resistance and weight savings essential to competitive racing platforms. The o-ring seal on the 8 AN side provides a leak-free connection when mated with corresponding male fittings, while the 10 AN side accommodates larger-diameter hoses and fittings to support increased system capacity. At 0.06 lbs with compact 2.65 x 1.25 x 3.75-inch dimensions, the adapter installs in tight engine bays without sacrificing clearance or accessibility. The single-unit design simplifies ordering and ensures direct fitment for system builders planning AN-line transitions.

This adapter is ideal for drag racing, road racing, and off-road competition builds where fuel delivery and cooling efficiency depend on matched line sizing and secure fittings. Engine builders and suspension technicians rely on AN fittings to standardize connections across diverse component suppliers, reducing leak points and simplifying maintenance during competition season. Whether upgrading a legacy fuel cell to modern AN plumbing or stepping up line size in a high-volume cooling loop, this inlet fitting addresses a common integration challenge in performance platform development.

AN fittings have been the industry standard for motorsports and aviation applications for decades because they offer consistent sizing, proven seal technology, and extensive aftermarket support. The -8 to -10 conversion size fits vehicles transitioning from compact fuel systems to larger-displacement engines or upgraded cooling demands, making this adapter a practical upgrade component for mid-build modifications and platform expansion.
