#6 Alum Line Wrench

The #6 Alum Line Wrench from MPD Racing is a double-end AN wrench engineered for precision work on aircraft-style fittings and high-performance racing systems. Designed for technicians, mechanics, and enthusiasts who demand reliability when connecting or servicing AN (Army-Navy) line fittings, this wrench eliminates guesswork and delivers the controlled grip needed for consistent, damage-free fastening. Its dual-end design maximizes efficiency by combining two common sizes in a single, lightweight tool.

Constructed from black anodized aluminum, the #6 Alum Line Wrench offers superior corrosion resistance while maintaining a low 0.11 lb weight that won't faigue your hand during extended use. The double-end configuration provides two wrench sizes in a compact 5.65-inch package, with a slim 0.5-inch profile that fits into tight engine bays and confined spaces where standard steel wrenches cannot reach. Anodized aluminum provides excellent durability against fuel, oil, and weather exposure—critical for applications in fuel systems, brake lines, and cooling circuits.

This wrench is essential for custom automotive builders, racing teams, and aircraft maintenance professionals working with AN fittings on fuel injection systems, hydraulic lines, and turbo plumbing. The lightweight aluminum construction makes it ideal for pit crews and mobile technicians who prioritize tool portability without sacrificing strength. Whether you're assembling a high-horsepower street rod, maintaining a race car's fuel system, or servicing experimental aircraft fuel lines, the #6 Alum Line Wrench delivers the precision grip and corrosion resistance required for reliable connections that won't weep or fail under pressure.
