#12 Race-Rite Crimp-On Hose End 45-Degree

The #12 Race-Rite Crimp-On Hose End 45-Degree is a precision fluid-line fitting engineered for high-performance fuel, oil, and coolant systems in race cars, hot rods, and heavily modified street vehicles. This adapter bridges the gap between rigid braided hose and engine bay components, allowing builders to route hydraulic lines with clean 45-degree angles that save space and improve under-hood aesthetics. Whether you're assembling a custom fuel system, upgrading transmission cooler lines, or installing a standalone engine management setup, this fitting provides the directional control that tight engine bays and complex plumbing layouts demand.

Built from black anodized aluminum, the #12 Race-Rite Crimp-On Hose End 45-Degree reduces weight while delivering corrosion resistance in demanding underhood environments. The crimp-on design requires a proper hose crimper tool and AN-sized hose, creating a permanent, leak-free seal that withstands fuel system pressure and thermal cycling. The 45-degree angle orientation eliminates sharp bends in braided hose runs, reducing turbulence, protecting hose from abrasion against frame rails or block surfaces, and extending component service life. Dual 12 AN connections—one to the hose, one to the system component—ensure compatibility with industry-standard -12 braided hose and female ports throughout professional racing and custom automotive applications.

This fitting is ideal for fuel system builders, engine swap specialists, and race mechanics who require precise hose routing without compromises on pressure rating or reliability. Installation requires a hydraulic hose crimper capable of -12 AN crimps; the finished assembly must be tested under pressure before engine start. The compact 2.5 x 2 x 5.6 inch footprint makes it suitable for crowded engine bays where space-efficient plumbing is non-negotiable. Use this fitting wherever -12 braided hose meets stationary components and a 45-degree direction change is required—fuel rails, surge tank inlets, transmission cooler ports, and custom intake manifold ports all benefit from its precise geometry and robust construction.
