#6 to 18MMx1.5 Adapter Fitting Power Steering

The #6 to 18MM x 1.5 Adapter Fitting Power Steering from EARLS is a precision hydraulic adapter engineered for builders and mechanics modifying power steering systems in performance and custom vehicles. This straight adapter fitting connects AN (Army-Navy) metric fittings to metric ISO thread ports, making it essential for high-pressure power steering line rerouting during engine swaps, chassis fabrication, or aftermarket steering pump installations. Whether you're upgrading a classic muscle car, building a street rod, or customizing a modern performance platform, this adapter ensures leak-free, reliable connections in demanding under-hood environments.

Constructed from hardened steel with zinc oxide coating, the #6 to 18MM x 1.5 Adapter Fitting Power Steering delivers superior corrosion resistance and durability in high-vibration automotive applications. The fitting features a 6 AN male port on one end and an 18 mm x 1.50 thread port with an integrated O-ring on the other, providing a sealed interface that eliminates the need for separate sealing washers or thread sealant—critical when working with pressurized power steering fluid. The straight-flow design minimizes turbulence and pressure loss, maintaining optimal steering response while the robust construction withstands the cyclic pressure spikes inherent to power steering systems during aggressive cornering and full-lock maneuvers.

Professional fabricators, engine swap specialists, and serious DIY enthusiasts benefit most from this adapter when custom-routing power steering lines to fit tight engine bay layouts or non-original pump locations. Its compact 1.7 x 0.95 x 2.95 inch footprint allows installation in space-constrained areas where standard factory fittings won't fit, while the lightweight 0.11 lb design eliminates added weight penalties. Compatible with any power steering system using 6 AN hose or tubing on one side and metric M18 x 1.5 female ports on the other, this EARLS adapter is ideal for LS engine conversions, fuel-injected restorations, and any steering system adaptation requiring metric-to-AN thread conversion.
