#3 Male AN Union

The Triple X Race Components #3 Male AN Union (HF-32033BLK) is a precision-engineered aluminum adapter fitting designed for high-pressure hydraulic and fuel line systems in motorsport and racing applications. This straight-style AN union connects two 3 AN male ports, making it an essential component for custom plumbing setups where direct port-to-port coupling is required.

Constructed from aluminum and finished in black anodized coating, this adapter offers excellent corrosion resistance and durability under demanding race conditions. The black anodized surface protects against oxidation while providing a professional appearance in engine bays and fuel system installations. The 3 AN (JIC -3) specification indicates a 3/16-inch port size, a standard in motorsport fuel injection, nitrous oxide delivery, and custom coolant line applications. This fitting's compact footprint (2.45 × 1.05 × 3.6 inches) and minimal weight (0.02 lbs) ensure it integrates cleanly into tight underhood spaces without adding unnecessary mass.

Built by Triple X Race Components, a recognized manufacturer of aftermarket hydraulic and fuel system components, this union is widely used by drag racers, road racers, and engine builders assembling custom fuel systems, intercooler piping, and specialty cooling circuits. The straight-through design eliminates 90-degree or 45-degree angles where space allows, simplifying plumbing runs and reducing potential leak points. A critical consideration during installation: ensure proper torque specifications for AN fittings to avoid over-tightening aluminum components, which can crack under pressure cycling.
