Nuke Performance M22x1.5 Fittings to AN

Bridge the Gap: Premium M22x1.5 Metric to AN Male Adapter Fittings

When plumbing a high-performance vehicle, you frequently encounter the M22x1.5 thread pitch. As a standard for high-volume fluid ports across major European and global motorsport manufacturers, M22 provides the physical size needed for massive flow. To integrate these components into a standard AN fluid system, a reliable, high-flow adapter is mandatory.

Where is M22x1.5 Commonly Used? M22x1.5 ports are heavily utilized in areas demanding maximum fluid transfer with minimal restriction:

• High-Performance Oil Coolers: Brands like Setrab, Mocal, and Nuke Performance standardly use M22x1.5 ports on their oil cooler cores.

• Oil Catch Cans & Breather Tanks: Used to safely route large-diameter crankcase ventilation lines.

• Custom Fuel Cells & Surge Tanks: Found on high-volume fuel delivery covers and fuel pump manifolds.

Engineered for High Flow and Chemical Resistance Universal plumbing fittings can often narrow down internally, creating a bottleneck that drops pressure. Premium motorsport M22-to-AN adapters feature an optimized, oversized internal bore to maintain maximum flow velocity. Additionally, because they are sealed via a metric face O-ring rather than tapered threads, choosing a fitting with Viton O-rings ensures the seal will never degrade, swell, or leak when exposed to aggressive fluids like racing oil, E85, or pure methanol.

Available Configurations: Adapt your M22x1.5 port directly to the exact hose size your project demands:

• M22 to AN-6 / AN-8: Ideal for standard fuel delivery lines and smaller catch cans.

• M22 to AN-10 / AN-12: The gold standard sizing for engine oil coolers and main fuel system returns.

• M22 to AN-16: Designed for massive dry sump lines and high-volume water/coolant plumbing.
