Aluminum Adjustable AN Wrench -10an to -20an

The PROFORM Aluminum Adjustable AN Wrench for -10AN to -20AN fittings is a single-end tool engineered for high-performance fuel system, hydraulic, and fluid line work. Built from aluminum construction with blue anodized finish, this adjustable wrench spans two standard AN sizes in one compact tool, eliminating the need to carry separate wrenches for -10AN and -20AN connections commonly found in street rods, drag racing platforms, and performance engine builds.

AN (Army-Navy) fittings are critical pressure-sealed connections that demand precise torque and proper wrench engagement to prevent stripping or leakage. The adjustable design of this PROFORM tool accommodates both -10AN and -20AN sizes, allowing technicians and builders to work efficiently without switching between fixed-size wrenches. The aluminum body keeps weight down for extended wrench work while the anodized coating resists corrosion in shop and engine bay environments. At 0.64 lbs with compact 4.95-inch length, the tool balances accessibility in tight engine compartments with sufficient leverage for secure grip on fitting nuts.

This wrench serves builders and technicians working on fuel injection systems, custom cooling loops, and hydraulic brake conversions where dual-size AN fitting capability streamlines assembly. Single-end design focuses grip force directly on the fitting, reducing risk of rounded corners on hard-anodized or stainless steel nuts. The tool is essential for anyone servicing or installing performance fluid systems that mix standard -10AN and -20AN line sizes in the same vehicle.

AN wrench sets are foundational for fuel system work, and having dual-size capacity in a single compact tool reduces clutter on the bench or in mobile service kits. Whether you're building a custom fuel delivery system, installing performance brakes, or servicing engine bay plumbing, this PROFORM adjustable wrench delivers the precision fitting engagement serious fabrication demands.
