AN Tee -4

The ALLSTAR PERFORMANCE AN Tee -4 is a three-way adapter fitting designed to consolidate hydraulic or pneumatic lines in high-performance engine bay and fuel system applications. This aluminum tee junction accepts three 4 AN male ports, making it essential for builders who need to merge multiple fluid pathways into a single manifold point without additional adapters or fittings cluttering the engine compartment.

Built from aluminum with black anodized finish, the fitting resists corrosion and blends seamlessly into modern engine bays while maintaining structural integrity under pressure cycling. The 4 AN specification indicates a 0.5-inch female port size at each junction, a standard in high-flow fuel delivery, nitrous systems, and hydraulic power steering setups. The symmetrical three-way design allows equal flow distribution or selective branching depending on circuit configuration, and the anodized coating protects against salt air and fluid degradation over extended use.

This adapter is ideal for street rods, race cars, marine engines, and off-road vehicles where space constraints demand compact fluid management. It's particularly valued in fuel system upgrades where multiple fuel lines converge at a regulator or gauge manifold, and in pressurized cooling systems where bypass and distribution circuits must merge efficiently. The lightweight construction—0.04 lbs—ensures minimal impact on overall system weight while delivering reliable performance across repeated thermal cycles and vibration-heavy environments.

ALLSTAR PERFORMANCE is recognized for manufacturing practical engine compartment solutions that prioritize fitment accuracy and materials quality. This tee fits standard 4 AN hose and rigid tubing systems, making it a direct bolt-in for most custom builds that already use AN-specification plumbing.
