Stubby Aluminum Adj. AN Wrench Set -3an to -20an

The PROFORM Stubby Aluminum Adjustable AN Wrench Set (-3AN to -20AN) is a compact, two-piece tool kit designed for precision work with Army-Navy (AN) fittings. This set is ideal for technicians and operators who need quick access to various AN fitting sizes without the bulk of multiple tools. Its compact design makes it essential for aviation maintenance, fuel system work, hydraulic line assembly, and motorsport applications where space and weight are critical.

Constructed from lightweight aluminum, this wrench set weighs just 0.5 lbs, making it a significant advantage in environments where portability is essential. The adjustable mechanism allows for precise engagement with AN fitting hex profiles, which is crucial for preventing rounding and ensuring leak-free connections in high-pressure systems. The stubby profile keeps overall dimensions minimal, measuring 6.05 x 1.1 x 9.9 inches.

This wrench set is particularly beneficial for aviation mechanics, military aircraft maintainers, high-performance racing teams, and aerospace technicians who work with standardized AN fittings in confined spaces. The two-piece configuration provides flexibility for accessing fittings in tight engine compartments and complex plumbing layouts. Operators in marine environments, helicopter hangars, and field maintenance operations will find this tool kit indispensable.
