Union AN Male -10

The ALLSTAR PERFORMANCE Union AN Male -10 (SKU ALL 49714) is a straight adapter fitting designed to connect two -10 AN male ports in high-pressure fluid systems. Machined from aluminum and finished in black anodize, this compact adapter serves as a reliable junction point in custom hydraulic, fuel, and cooling line assemblies where AN-standard connections are required.

The -10 AN designation refers to a metric thread size (M16×2.0) with a 45-degree flare seat, widely adopted in racing, performance, and industrial applications. The aluminum construction keeps weight minimal—critical in motorsports—while the black anodized finish provides corrosion resistance in both dry and humid environments. This straight configuration allows inline connection of two hoses or hard-line fittings without bends or angles, simplifying installation in tight engine bays or chassis layouts. The precision machining ensures proper seal integrity under pressure cycling, a requirement in systems ranging from fuel injection to transmission cooling.

This adapter is ideal for fabricators, engine builders, and performance technicians assembling custom fuel systems, supercharger feeds, or auxiliary cooling circuits in drag racing, circle track, or street performance builds. It's also suited for restoration work where OEM-equivalent AN plumbing is preferred over older steel tubing for reliability and leak resistance. The compact 2.15 × 1.45 × 4-inch footprint allows placement in congested engine compartments where space is at a premium.

AN fittings maintain a strong position in performance and professional applications because they standardize thread size, flare angle, and hose compatibility across manufacturers—eliminating confusion and mismatches that plague other quick-connect systems. The -10 size strikes a balance between flow capacity and installation ease, making it a workhorse in mid-sized systems.
