12AN Tee with Female Swivel on Branch Black

The 12AN Tee with Female Swivel on Branch Black by REDHORSE PERFORMANCE is a purpose-built hydraulic and fuel line adapter engineered for high-performance automotive systems where multi-directional flow control is essential. This fitting serves as a critical junction point in custom fuel systems, turbo setups, cooler lines, and boost plumbing where three separate 12 AN connections must converge at a single manifold point. Whether you're building a modified engine bay, upgrading your fuel delivery system, or designing a complex coolant circuit, this tee adapter eliminates the need for bulky external manifolds and reduces clutter in tight engine compartments.

Constructed from aluminum and finished in black anodize, the 12AN Tee features a robust configuration with 12 AN male ports on two opposite sides and a 12 AN female swivel connection on the branch, allowing flexible hose routing without stress on the fitting itself. The female swivel design on the branch port is critical for vibration dampening and ease of installation—it permits final hose alignment without over-torquing or twisting the main body, a feature that prevents line fatigue and extends system longevity. Black anodizing provides corrosion resistance in engine bays exposed to salt, moisture, and thermal cycling, while the compact 4 x 1.5 x 6 inch footprint ensures it fits within space-constrained applications typical of turbo manifold plenums or fuel rail configurations. At 0.305 lbs, this lightweight adapter minimizes unsprung weight and is engineered to handle the pressure demands of modern EFI systems, fuel-cell setups, and forced induction cooling circuits.

Serious engine builders, performance technicians, and DIY enthusiasts working on turbocharged, supercharged, or naturally aspirated systems will find this fitting indispensable for custom fuel distribution, intercooler plumbing, and boost control circuits. It is ideal for applications requiring three-way flow management where hose compatibility and routing flexibility take priority—think complex LS swaps, rotary conversions, or heavily modified racing platforms where OEM manifolds don't accommodate aftermarket fuel rails or cooler configurations. Compatibility with standard 12 AN hose and AN fittings ensures universal fitment across brands; simply match all three connections to 12 AN male or swivel fittings and secure with appropriate hose clamps or compression fittings rated for your system pressure.
