Union Adapter Fitting; S ize -3 AN x -3 AN

The Vibrant Performance -3 AN to -3 AN Union Adapter Fitting (part number 10230) is a straight-port male-to-male connector engineered for high-pressure hydraulic and fuel line applications. This aluminum adapter fitting delivers reliable fluid transfer in demanding motorsport, racing, and performance automotive environments where secure, leak-free connections are essential to system integrity.

Constructed from aluminum and finished in black anodizing, this fitting resists corrosion and oxidation while maintaining a clean appearance in engine bays and fuel systems. The straight-port design eliminates flow restriction and pressure loss at the junction point, a critical factor in precision fuel delivery systems and custom hydraulic setups. The -3 AN specification (equivalent to 3/16-inch tubing inner diameter) provides the flow capacity needed for mid-range performance applications while maintaining compact installation profiles in tight underhood or cockpit spaces. Weighing just 0.02 pounds, this lightweight adapter adds negligible mass to any system.

This union adapter fitting is ideal for builders and technicians assembling custom fuel injection systems, turbocharger plumbing, cooling circuits, and modular hydraulic networks where AN-specification connectors are standard. The male-to-male configuration allows direct coupling of two female-threaded hose ends or block ports, simplifying system layout and reducing component count. Vibrant Performance fittings are widely recognized in the racing and high-performance aftermarket for consistent quality and dimensional accuracy that meets or exceeds SAE J518 standards.
