#4 Tee w/ Female Swivel

The #4 Tee w/ Female Swivel from Triple X Race Components is a precision adapter fitting engineered for high-performance fuel, oil, and coolant line routing in custom engine builds and race applications. This aluminum tee junction allows mechanics and fabricators to split or combine fluid circuits with confidence, using industry-standard AN fittings that have become the backbone of modern automotive plumbing in street rods, drag cars, and turbocharged platforms. Whether you're designing a custom fuel distribution manifold, integrating multiple cooling circuits, or routing pressurized systems through tight engine bays, this adapter delivers the reliability required in demanding builds.

This tee features one 4 AN female swivel port and two 4 AN male ports, allowing flexible connection angles and accommodating vibration without crimping or kinking lines. The black anodized aluminum construction resists corrosion while maintaining a clean, professional appearance in engine bays, and the swivel female inlet prevents rotation stress on incoming hose assemblies—critical when working with tight-radius bends or pre-assembled fuel and coolant lines. Swivel connections reduce installation labor and protect the integrity of hose crimps, a key advantage when retrofitting complex cooling or fuel systems into vintage chassis or modern competition vehicles.

This adapter suits any build using 4 AN plumbing systems—custom fuel injection setups, engine bay cooling loops, turbo oil supply and return lines, and prototype engine stands. The compact 1.85 x 0.65 x 2.95 inch footprint fits efficiently in restricted spaces without requiring custom fabrication, and the lightweight design (0.04 lbs) adds negligible weight to systems. Installation is straightforward: thread the female swivel end onto incoming hose, then secure the two male outlets with standard AN hose clamps or fittings, ensuring all connections are torqued per AN fitting standards to prevent leaks under pressure.
