8AN Tee with Female Swivel on Branch Black

The 8AN Tee with Female Swivel on Branch Black from Redhorse Performance is a precision hydraulic fitting engineered for high-flow fuel, coolant, and brake line applications in custom engine builds and performance fuel systems. This tee configuration splits a single incoming line into two outgoing branches, making it essential for builders who need to distribute pressurized fluid to multiple components—such as fuel regulators, coolers, or dual carburetor setups—without sacrificing flow rate or creating restrictive bottlenecks. Whether you're tuning a naturally aspirated engine or managing boost pressure on a supercharged platform, this fitting delivers the reliability and durability that serious mechanics demand.

Constructed from robust aluminum with a black anodized finish, the 8AN Tee resists corrosion while maintaining a clean underhood aesthetic. The female swivel on the branch outlet allows a 360-degree connection angle, eliminating the need for additional adapters and reducing assembly complexity in tight engine bays where hose routing demands flexibility. The 8AN (AN8) designation indicates a nominal bore diameter of 1 inch, providing substantial flow capacity while maintaining structural integrity under sustained pressure spikes common in turbocharged and supercharged engines. Redhorse Performance's precision threading and seal surfaces ensure leak-free operation—critical when fuel vapors or coolant escape can compromise engine performance or create safety hazards.

This tee is ideal for fuel system upgrades, turbo coolant line installations, and brake system plumbing on street rods and track-focused builds. It pairs seamlessly with standard -8 AN hoses, adapters, and fittings from major performance suppliers, making it compatible with virtually any custom fuel rail, aftermarket fuel pump, or dual-circuit brake design. Installation requires only basic hand tools and a firm understanding of AN fitting torque specs (typically 10–15 ft-lbs for aluminum-to-aluminum connections). Mechanics and fabricators trust Redhorse Performance for OEM-grade reliability without the OEM price tag, making this 8AN Tee a cost-effective upgrade for anyone serious about system integrity.
