Tee Fitting -4 with Female -4AN Swivel

The Tee Fitting -4 with Female -4AN Swivel from Vibrant Performance is an essential hydraulic adapter for serious engine builders, fuel system designers, and powersports enthusiasts who demand reliable fluid routing in high-performance applications. This compact tee fitting serves as a critical junction point in custom fuel, oil cooling, or boost systems where three separate -4AN lines must meet at a single manifold. Whether you're fabricating a custom fuel rail on a turbocharged engine, integrating a remote oil cooler into a race build, or plumbing a complex boost control circuit, this fitting provides the precise connection geometry modern engine management demands.

Constructed to Vibrant Performance's exacting standards, this tee fitting features a female -4AN swivel port that accommodates standard -4AN braided hose with push-lock or compression fittings, eliminating thread-seal complications and allowing for quick disconnect capability during maintenance. The tee geometry distributes flow evenly across three outlets, minimizing turbulence and pressure drop—critical factors in fuel delivery systems where consistency directly impacts engine response and tuning stability. The compact 3.54 x 1.25 x 6.3 inch footprint and minimal 0.03 lb weight make integration straightforward in tight engine bay layouts without sacrificing durability or flow characteristics that matter in high-boost or high-RPM environments.

This fitting is ideal for custom fuel system plumbing, turbocharger boost control manifolds, remote oil cooler integration, and any application requiring reliable -4AN tee junction points in motorsports or street performance builds. Mechanics and fabricators working on LS swaps, forced induction engine conversions, and standalone ECU setups will appreciate the precision fit and compatibility with industry-standard Vibrant Performance hose and fitting ecosystems. Installation is straightforward—thread the -4AN female swivel onto your manifold or hardline block, then connect your three hose runs with appropriate -4AN fittings, ensuring all connections are torqued to specification for leak-free operation under boost or sustained fuel pressure.
