Alum Adj Wrench 0-20AN

The Alum Adj Wrench 0-20AN from Allstar Performance is a precision adjustable wrench designed for high-performance fuel system, transmission cooler, and brake line work where AN (Army/Navy) fittings are prevalent. This tool is ideal for automotive technicians and engine builders who require accuracy when assembling or servicing AN hose fittings and adapters. It eliminates the need for multiple fixed wrenches and helps reduce fastener rounding in tight engine bay spaces.

Constructed from lightweight aluminum alloy, the Alum Adj Wrench 0-20AN is designed to grip six-point AN fitting heads without slippage or damage to critical fasteners. The wrench features a robust adjustment mechanism that allows for precise jaw alignment and consistent clamping force, which is crucial when torquing down fittings that cannot tolerate over-tightening or cross-threading. Weighing just 0.62 lbs, it minimizes fatigue during extended overhead work while maintaining the necessary rigidity.

Professional mechanics, engine builders, and performance enthusiasts will find this tool invaluable when working with AN fittings in fuel delivery and brake systems. The 12-inch length provides ample leverage for stubborn fittings without requiring excessive force that could strip soft aluminum adapters. Whether tuning a street machine or maintaining late-model performance vehicles, this wrench is an essential addition to any toolkit.
