Tee Fitting -3AN with Female -3AN Swivel

The Tee Fitting -3AN with Female -3AN Swivel is an essential fluid distribution component for custom fuel, oil, and coolant systems in performance and modified vehicles. This adapter allows you to split flow from a single inlet line into two separate outlet paths, making it indispensable for fuel rail upgrades, dual-stage fuel pressure regulation, and complex plumbing layouts common in turbo installations and engine swaps. Whether you're building a high-boost fuel system or routing secondary cooling circuits, this tee fitting provides the junction point your system demands.

Engineered with a female -3AN swivel port design, this fitting accommodates standard -3AN hose barbs and adapters with smooth internal passages to minimize turbulence and pressure drop across the junction. The swivel configuration reduces stress on hose routing by allowing fine-tuned angular adjustment without kinking or binding, critical when space is tight in engine bays or when working around existing components. The compact 3.54-inch length and lightweight 0.02-pound construction integrate seamlessly into tight installations, while the proven Vibrant Performance manufacturing standard ensures leak-free operation under sustained pressure cycling typical of modern fuel systems running 40+ PSI.

This tee fitting suits technicians and enthusiasts upgrading fuel delivery on LS swaps, stroker builds, and turbocharged platforms where OEM fuel lines cannot support modified injector counts or pressure requirements. It pairs seamlessly with -3AN hose, adapters, and regulator outlets in both carbureted and EFI applications. Installation requires standard hose crimping tools and basic plumbing knowledge; the swivel female end simplifies alignment during final assembly. For reliable, repeatable results in custom fuel system builds, this Vibrant Performance fitting delivers the junction architecture your system design depends on.
