-16AN Wrench - Anodized Black

The -16AN Wrench - Anodized Black from Vibrant Performance is a precision tool engineered for serious automotive enthusiasts and professional mechanics working with high-performance fuel systems, oil coolers, and custom hydraulic lines. This specialized wrench addresses the unique demands of AN (Army-Navy) fitting connections, which have become the industry standard in aftermarket engine builds, turbo installations, and race car plumbing. Whether you're assembling a fuel-injected engine swap, routing braided stainless steel lines, or maintaining a turbocharged setup, this wrench ensures proper fitment and torque application without stripping or damaging your investment-grade fittings.

Vibrant Performance engineered this -16AN wrench with a black anodized finish that resists corrosion and identifies it clearly in your toolbox during complex fuel or cooling system work. The anodized aluminum construction provides durability while remaining lightweight—at 0.26 lbs, it won't fatigue your hand during extended underhood sessions. The wrench's compact profile (9.95 inches long with a 0.6-inch width) allows access to tightly packaged AN fittings in modern engine bays where space is at a premium. This design prevents rounding of the hexagonal fitting heads, which is critical when working with expensive stainless steel braided lines or titanium fittings commonly found in competition vehicles.

This tool is indispensable for anyone building or maintaining late-model performance vehicles, LS swaps, fuel system upgrades, or turbo applications where AN-sized connections are standard. Mechanics, fabricators, and DIY builders rely on properly sized AN wrenches to ensure leak-free connections that withstand boost pressure, high fuel flow, and thermal cycling. The -16AN size fits standard -16 AN bulkhead fittings and adapters, making it compatible with both metric and imperial fuel system designs common in street rods, track cars, and modern EFI conversions.
