Alum #4 Male Branch Tee

The Alum #4 Male Branch Tee by AEROQUIP is a critical fluid distribution fitting for custom fuel, coolant, and hydraulic line systems in high-performance vehicles and engine builds. Designed for mechanics and enthusiasts who demand precision plumbing in modified powertrains, this tee allows controlled branching of fluid lines while maintaining structural integrity under pressure. Whether you're assembling a race engine fuel system, upgrading cooling circuits, or fabricating custom hydraulic lines, this aluminum branch tee delivers the reliability that professional installations require.

Constructed from lightweight aluminum, the Alum #4 Male Branch Tee accommodates size #4 tubing and fittings, a standard specification in automotive fuel and coolant applications. The male branch configuration enables seamless integration into existing line assemblies, with three ports providing one inlet and two outlets (or vice versa depending on flow direction). Aluminum construction reduces overall system weight compared to steel alternatives while maintaining pressure rating and corrosion resistance—an essential advantage in engine bays exposed to heat cycling and moisture. The compact dimensions (2.3 x 1.1 x 3.7 inches) ensure installation flexibility even in tight underhood spaces typical of modified or turbocharged builds.

This AEROQUIP fitting is ideal for custom fuel system upgrades, aftermarket cooling line modifications, and complex hydraulic circuit fabrication where OEM manifolds won't fit or function. Technicians building LS-swapped vehicles, turbo conversions, and boutique engine projects rely on precision tees like this to split flow between fuel rails, coolant ports, and secondary distribution points. Installation requires standard AN line fittings compatible with size #4 tubing; ensure all connections are torqued to manufacturer specifications and tested under system pressure before full operation.
