Oil Cooler Fitting M22 x 1.5 ORB

The XRP-XTREME RACING PROD. Oil Cooler Fitting M22 x 1.5 ORB is a precision adapter engineered to connect high-performance cooling systems with reliability and leak-free operation. This straight fitting transitions from 10 AN male ports to M22 x 1.5 O-ring boss ports, making it essential for race engine oil cooler installations, turbo systems, and advanced marine thermal management applications where flow consistency and pressure integrity are non-negotiable.

Constructed from aluminum and finished in black anodizing, this fitting resists oxidation and corrosion in demanding saltwater and high-heat environments. The O-ring boss design provides a metal-to-metal seal that maintains pressure across throttle transitions and dynamic load changes, eliminating the thread-sealant dependency found in NPT connections. Weighing just 0.08 lbs, the compact profile fits tight engine bays and avoids unnecessary system weight that impacts performance tuning and fuel economy calculations.

This adapter suits serious offshore anglers upgrading their engine cooling systems, race teams optimizing thermal flows, and marine mechanics standardizing cooler installations across multiple boat platforms. The M22 x 1.5 ORB thread pitch is OEM-standard on many modern marine engines and aftermarket coolers, making this fitting a critical compatibility bridge when upgrading fuel coolers, transmission coolers, or hydraulic systems to high-performance AN-line plumbing standards.

AN fittings have long been the preferred choice in motorsports and high-reliability marine applications because their standardized flare and port sizing eliminate guesswork and reduce assembly errors. The 10 AN to M22 x 1.5 conversion allows builders to source performance coolers designed around AN systems while maintaining compatibility with OEM engine block ports or existing manifold equipment.
