#4 Tee Fitting Black

The #4 Tee Fitting Black by FRAGOLA is a precision hydraulic and pneumatic adapter designed for high-performance fuel, oil, coolant, and air line systems in automotive, marine, and industrial applications. This three-way junction fitting allows technicians and enthusiasts to split or combine fluid flow across three separate lines with equal 4 AN ports, making it essential for custom fuel systems, supercharger setups, and transmission cooler configurations where reliable, leak-free connections are critical.

Engineered from lightweight aluminum and finished in black anodized coating, the #4 Tee Fitting Black resists corrosion while delivering superior durability in demanding environments. The 4 AN male threads on all three ports (inlet and dual outlets) ensure compatibility with standard 4 AN hose fittings and comply with SAE J518 specifications for consistent, pressure-rated performance. Black anodizing not only enhances corrosion resistance but also provides a professional appearance that matches modern engine bay aesthetics.

Installation is straightforward for experienced builders and professional shops alike—simply thread 4 AN hose adapters or lines into each of the three ports using appropriate AN wrenches and thread sealant. The compact 2.85-inch length and minimal 0.03-pound weight make it ideal for tight engine bays where space constraints demand efficient routing. Whether upgrading a fuel system distribution block, connecting multiple coolers, or splitting pressurized lines, the FRAGOLA #4 Tee Fitting Black is the dependable, OEM-quality choice for systems requiring precision flow control and unwavering reliability.
