Male -6AN Tee Fitting with 1/8in NPT Port

The Male -6AN Tee Fitting with 1/8in NPT Port is a precision hydraulic distribution component engineered for custom fuel, coolant, and boost systems in high-performance automotive builds. This aluminum fitting serves as a critical junction point in fuel lines, intercooler circuits, and turbo setups where you need to split flow to multiple destinations without compromising system pressure or flow capacity. Whether you're integrating secondary fuel pressure gauges, adding auxiliary cooling lines, or building a complex fuel system architecture, this tee fitting delivers the reliability that serious tuners and mechanics demand.

Built by Vibrant Performance—a trusted name in aftermarket plumbing solutions—the Male -6AN Tee Fitting features a -6AN inlet/outlet configuration (3/8-inch SAE thread) paired with a 1/8-inch NPT threaded port for gauge installation or diagnostic taps. The compact aluminum construction withstands typical fuel system pressures (40–60 psi) while maintaining tight tolerances that prevent weeping under vibration. The tee geometry distributes flow evenly across branches, reducing turbulence and pressure drop, which is especially important in fuel systems where consistency directly impacts injector spray patterns and engine tuning stability.

This fitting is ideal for EFI conversions, fuel rail upgrades, and boost control circuits where a secondary port for monitoring or distribution is essential. Installation requires standard -6AN hose ends (typically crimped or reusable push-lock style) and basic hand tools; the 1/8 NPT port accepts common pressure senders, ball valves, or plugs depending on your system design. Mechanics and fabricators building everything from street turbo builds to dedicated race fuel systems choose Vibrant fittings for their dimensional accuracy and proven longevity in demanding engine bay environments.
