Adapter Fitting Bulkhead Tee 3an

The Adapter Fitting Bulkhead Tee 3AN from EARLS is a precision hydraulic and fuel line distribution component designed for high-performance automotive systems where reliable fluid routing and pressure integrity are essential. Built for enthusiasts and professional mechanics who demand leak-free connections in custom fuel systems, turbo boost lines, coolant circuits, and brake fluid applications, this compact tee adapter eliminates the need for multiple separate fittings and reduces potential failure points in complex plumbing layouts.

Manufactured to EARLS' exacting standards, this bulkhead tee fitting accommodates three 3AN hose connections in a single, space-efficient body, allowing you to split or combine fluid flow with zero restriction and zero leakage risk. The 3AN sizing corresponds to a 3/8-inch hose diameter, which is the industry standard for fuel and coolant circuits in sport compact and mid-range displacement engines, delivering flow rates suitable for carbureted, fuel-injected, and supercharged applications. The precision-machined aluminum construction ensures durability under pressure cycling while the finish resists corrosion from fuel, coolant, and brake fluid contact—critical in underhood environments subject to vibration and thermal stress.

This fitting is ideal for street rods, race cars, fuel cell installations, custom cooling system builds, and any application where factory manifold ports or single-outlet designs fall short. Mechanics and fabricators will appreciate the ease of installation and the reliability it brings to their projects, ensuring that performance and safety are never compromised.
