AN to Metric Fitting -10AN to M22 x 1.5

The AN to Metric Fitting -10AN to M22 x 1.5 from Vibrant Performance is a crucial adapter for modern engine builders and custom cooling system integrations. This fitting connects SAE Teflon hose standards with ISO metric port configurations, making it essential for fabricating custom fuel, coolant, or oil circulation lines on modified engines.

Designed to accommodate a -10AN fitting, which corresponds to a 5/8-inch hose, this adapter threads seamlessly into M22 x 1.5 metric ports commonly found on late-model engine blocks and radiator housings. The design minimizes turbulence and pressure drop across the transition, which is critical for managing fuel delivery or coolant flow in high-horsepower applications. Constructed with durable materials, this fitting is engineered to withstand vibration, thermal cycling, and the pressure demands of modified engine systems.

Mechanics and engine builders working on Euro-derived platforms, late-model domestic engines with metric cooling systems, or hybrid custom setups will find this adapter invaluable. It provides a reliable transition point between legacy -10AN components and metric-threaded engine block ports, ensuring compatibility and performance in various applications.
