Double Ended Alum Wrench -12/-16 Fitting

The Double Ended Aluminum Wrench -12/-16 Fitting from Allstar Performance is a specialized tool designed for technicians and engine builders who require precision in high-performance hydraulic and fuel system applications. This wrench features both -12 AN and -16 AN fittings on opposing ends, making it a practical choice for those assembling or servicing braided hose lines, fuel rails, and hydraulic manifolds.

Constructed from lightweight aluminum alloy, this double-ended design helps reduce hand fatigue during extended use while providing the necessary rigidity to apply controlled torque. The wrench head geometry is precision-machined to match AN fitting profiles accurately, preventing play and wobble that can damage expensive braided lines or aluminum manifold ports during assembly or disassembly.

This wrench is essential for anyone building or servicing fuel systems, oil coolers, transmission coolers, or intercooler plumbing on custom vehicles. Its compact design allows it to fit into tight spaces where full-sized wrenches cannot access, making it particularly beneficial for modern EFI conversions and turbo installations.
