4AN Male to 4AN Male Tee Blue

The 4AN Male to 4AN Male Tee Blue from REDHORSE PERFORMANCE is a precision hydraulic adapter engineered for custom fuel, coolant, and brake line distribution in high-performance automotive builds. This tee fitting allows a single AN line to branch into two separate circuits, making it essential for fuel injection tuning, nitrous oxide systems, multi-pump cooling loops, and advanced fuel management setups. Whether you're upgrading a street rod's fuel delivery or configuring a race engine's complex plumbing, this adapter consolidates connections without sacrificing flow or introducing weak points in your system.

Constructed from premium aluminum alloy, the 4AN Male to 4AN Male Tee Blue features full 4AN (AN4) porting on all three ports, ensuring consistent pressure handling and minimal turbulence across split circuits. The blue anodized finish serves dual purposes: corrosion resistance in engine bay environments and visual circuit identification in complex plumbing layouts. Each port is precision-machined to SAE JIC flare standards, guaranteeing leak-free connections when paired with proper AN hose and fittings. The compact 2.9 x 1.1 x 3.85-inch profile allows installation in tight engine compartments without requiring relocations of neighboring components.

This fitting benefits fuel system builders, custom fabricators, and engine tuners who demand reliable flow distribution under boost or naturally aspirated conditions. Install the 4AN Male to 4AN Male Tee Blue inline with 4AN hose and fittings using a -4 wrench—no special tools required. Compatible with gasoline, diesel, and methanol fuel systems, as well as water, coolant, and low-pressure air lines. Redhorse Performance's reputation for durability makes this tee a trusted choice for street, drag, and road-course vehicles where system reliability cannot be compromised.
