#4 Tee Fitting

The FRAGOLA #4 Tee Fitting is a precision aluminum adapter designed for high-flow fuel and fluid distribution systems requiring equal-outlet manifold capability. This 4 AN male tee fitting serves as a three-way junction, accepting a single inlet and splitting flow to two independent outlets—essential for applications where fuel or coolant must feed multiple destinations simultaneously without pressure loss across lines.

Constructed from aluminum and finished in blue anodizing, this FRAGOLA adapter resists corrosion while providing excellent material compatibility with modern fuel systems and coolant circuits. The 4 AN male ports (1/2-inch-20 UNF threads) ensure secure, leak-free connections across all three terminations. The compact footprint—measuring just 4.15 inches long—allows installation in space-constrained engine bays and fuel-distribution configurations. At 0.04 lbs, the fitting adds minimal weight to fuel management systems while maintaining the full flow capacity required by high-performance and racing applications.

This tee fitting is ideal for custom fuel systems, fuel injection conversions, nitrous oxide distribution lines, and coolant circuit upgrades where single-inlet, dual-outlet plumbing architecture is required. Street rods, race cars, and engine swaps frequently demand this exact configuration to feed multiple fuel rails, carburetors, or cooling circuits from a single supply line. The equal-outlet design ensures balanced pressure distribution, critical for maintaining fuel management system stability and preventing lean-condition anomalies in precision engine tuning.

FRAGOLA is recognized across fuel-system fabrication and performance automotive sectors for precision adapter quality and reliability under sustained high-flow conditions. This tee fitting pairs seamlessly with AN hose, fittings, and fuel rail assemblies meeting modern performance standards, making it a dependable choice for builders prioritizing system integrity and pressure stability.
