Aluminum AN Wrench Set Double Ended 6AN to 12AN

The PROFORM Aluminum AN Wrench Set Double Ended 6AN to 12AN is a four-piece precision tool kit designed for fuel system, coolant line, and hydraulic fitting work on high-performance engines and racing applications. Built from lightweight aluminum construction with multi-color anodized finish, this double-ended wrench set covers the most commonly used AN (Army-Navy) fitting sizes in a compact, portable format ideal for both stationary shops and mobile service.

Double-ended design eliminates the need to carry separate single wrenches, combining 6AN through 12AN sizes in just four tools. The aluminum construction reduces weight without sacrificing strength—a critical advantage when working in engine bays where tool mass matters. Multi-color anodization helps identify each wrench size instantly, reducing fumbling during time-sensitive installations or troubleshooting. The included protective case keeps wrenches organized and protected from corrosion during storage and transport, essential for maintaining the precision fit required by AN fittings.

This set serves engine builders, fuel system integrators, and performance technicians who need reliable AN fitting tools without unnecessary weight or bulk. Whether assembling a custom fuel system, servicing a race engine, or maintaining hydraulic circuits, the 6AN to 12AN range covers the majority of light-duty and medium-duty applications encountered in street performance and competition work.

AN wrenches differ fundamentally from standard metric or SAE tools—they are specifically designed to fit the hexagonal body of AN fittings without stripping or slipping. This precision fit is non-negotiable when working with pressurized fuel, coolant, and hydraulic systems where a rounded fitting can result in leaks, pressure loss, or catastrophic failure. A dedicated AN wrench set is an industry standard for anyone working on modern performance platforms.
