AN Tee -3 with 1/8 NPT on Run

The AN Tee -3 with 1/8 NPT on Run from Allstar Performance is a precision fluid-routing component designed for custom fuel, oil, coolant, and brake system plumbing on street rods, race cars, and modified performance vehicles. This compact tee adapter serves as a critical junction point in pressurized systems, allowing you to split or combine fluid flow while maintaining system integrity under demanding conditions.

Machined from aluminum alloy with a hard-anodized finish, this fitting handles the vibration, thermal cycling, and pressure spikes inherent to forced induction, fuel injection tuning, and high-flow cooling circuits. The integral 1/8 NPT threaded port on the run line allows for gauge installation, drain, or secondary feed capability, simplifying your plumbing schematic and reducing potential leak points in the engine bay.

This fitting excels in applications where you need flexible flow distribution—fuel line T-offs for carburetors or EFI rails, oil pressure sensing for management systems, or coolant bypass routing on LS or big-block conversions. Installation is straightforward with AN hose fittings, making it a reliable choice for fabricators and engine builders seeking clean, professional-grade installations.
