Aluminum Wrench Set Double Ended

The ALLSTAR PERFORMANCE Aluminum Wrench Set Double Ended (SKU ALL 11120) is a 6-piece AN wrench kit engineered for precision work on aircraft fuel systems, hydraulic lines, and high-pressure applications where flare nut connections are critical. Built from lightweight aluminum construction with blue and red anodized finishes, this double-ended wrench set covers AN sizes 4 through 16, making it essential for mechanics and technicians working on vintage aircraft, race engines, and custom automotive builds where AN fittings are standard.

Double-ended design maximizes functionality by offering two different AN sizes on a single wrench, reducing the number of tools required on the bench or in the field. The aluminum construction keeps weight minimal—critical for aircraft maintenance where every pound matters—while the anodized finish provides corrosion resistance during storage and extended use. The 6-piece configuration delivers comprehensive coverage across the most commonly encountered AN sizes, eliminating the need for partial kits or incomplete sets that leave gaps in your tool collection.

This wrench set is purpose-built for technicians and builders who demand accuracy when tightening or loosening AN flare fittings without stripping. AN wrenches feature a shallow offset head design that accommodates the tight spaces typical in engine compartments and fuel systems. The color-coded anodized finish—blue and red—enables quick visual identification of different wrench sizes during fast-paced shop work. Whether you're overhauling a classic aircraft engine, maintaining a high-performance racing fuel system, or assembling custom hydraulic assemblies, having a dedicated set of AN wrenches eliminates fumbling with standard SAE tools that won't fit properly on aviation-spec fittings.

AN (Army-Navy) fittings have been the standard in aerospace and military applications since World War II, and their precision thread and flare design demands purpose-designed wrenches. Using general-purpose wrenches on AN connections risks damaging both the fitting and the tool itself. This dedicated kit ensures compatibility and proper torque application, giving builders and mechanics the confidence that fuel, hydraulic, and pressurized systems are sealed correctly.
