#3 X 1/8 NPT Tee On Branch

The Triple X Race Components #3 X 1/8 NPT Tee On Branch fitting is a precision adapter designed for high-pressure hydraulic and fuel line applications in racing and performance vehicle systems. This black anodized aluminum tee fitting combines three connection points—two 3 AN male ports and one 1/8 inch NPT male port—enabling complex fluid routing in tight engine compartments and fuel cell configurations where multiple line junctions are required.

The 3 AN (AN3) male threads accept standard -3 AN hose fittings and provide reliable sealing under the elevated pressures common in racing fuel systems, turbo boost lines, and hydraulic brake circuits. The 1/8 inch NPT (National Pipe Thread) male port accommodates gauge ports, pressure sensors, or auxiliary feed lines, making this tee extremely versatile for custom plumbing. The black anodized aluminum construction resists corrosion while remaining lightweight—a critical consideration in weight-sensitive motorsports applications. Weighing just 0.03 lbs and measuring 1.7 x 0.5 x 2.9 inches, the fitting occupies minimal space without compromising flow capacity or structural integrity.

This adapter is essential for builders and tuners constructing custom fuel injection systems, race engine fuel distribution blocks, or turbo intercooler plumbing where branch points must consolidate multiple fluid streams. It serves applications ranging from drag racing fuel systems to road course endurance machines where reliability and efficient line management are non-negotiable. Triple X Race Components manufactures fittings to exacting tolerances, ensuring consistent thread engagement and leak-free performance across thousands of operating miles and thermal cycles.

AN fittings remain the industry standard in motorsports because they provide superior vibration resistance compared to straight NPT connections alone. By combining AN male ports with NPT capability in a single body, this tee eliminates the need for multiple adapters and reduces potential leak points in complex systems. The black anodized finish protects the aluminum substrate while maintaining a professional appearance under the hood.
