3AN Tee with Female Swivel on Run Black

The 3AN Tee with Female Swivel on Run in Black from REDHORSE PERFORMANCE is a critical hydraulic fitting for custom fuel, coolant, and brake line systems in high-performance automotive builds. This tee connector allows you to split flow from a primary line into two secondary branches, making it essential for turbo installations, fuel system upgrades, and precision cooling setups where routing flexibility is non-negotiable. Whether you're tuning a street car or track-prepped race vehicle, a properly rated tee fitting ensures system integrity and prevents pressure loss that could compromise performance or reliability.

The 3AN designation indicates a -3 AN (Army-Navy) port size, the industry standard for compact motorsport applications where space is limited and flow efficiency matters. The female swivel fitting on the run (main axis) accepts male AN connectors and allows 360-degree rotation, eliminating hose kinking and enabling clean, professional line routing in tight engine bays. REDHORSE PERFORMANCE aluminum construction delivers lightweight durability with superior corrosion resistance, critical in high-vibration environments where steel fittings can fatigue or seize. The black anodized finish provides both aesthetic appeal and additional oxidation protection, ensuring long service life in both street and racing applications.

This fitting suits custom fuel system builders, turbo installers, and performance cooling system designers running AN plumbing infrastructure. Pair it with matching 3AN hose, fittings, and adapters to create modular, upgradeable systems that accommodate future modifications. Installation is straightforward for anyone experienced with AN fittings—use appropriate wrenches on both the swivel body and connector to prevent component rotation and ensure leak-free seals. Verify your system pressure rating and confirm all connections are torqued to specification for safe, reliable operation on street or track.
