Mate Series Tee Adapter

The Mate Series Tee Adapter (Part No. T12) is a three-way barbed tee fitting designed for fluid and coolant line distribution in automotive cooling systems, fuel lines, and custom plumbing applications. With 1/2-inch barb connections on all three ports, this adapter enables reliable branching of hoses in engine bay configurations, retrofit installations, and performance cooling setups where flow distribution across multiple circuits is required.

The tee adapter's three equal 1/2-inch barb ports provide consistent flow paths with minimal turbulence and pressure drop across each branch line. Barbed fittings create a mechanical grip when hose is seated, offering a non-releasable connection ideal for systems running constant pressure or experiencing vibration—common conditions in engine compartments and high-performance cooling loops. The compact 2 x 1 x 3-inch profile fits easily into tight engine bay spaces typical of modern vehicle layouts, while the 0.05-pound weight adds negligible mass to the cooling circuit.

This fitting suits technicians and enthusiasts upgrading stock cooling systems with auxiliary radiators, fan controllers, or temperature monitoring sensors. OEM replacement scenarios, aftermarket coolant distribution lines, and custom water-cooling loops all benefit from the Mate Series tee adapter's straightforward barb connection standard and three-way branching capability. The matching 1/2-inch diameter across all ports simplifies hose selection and ensures uniform flow characteristics through each outlet.

Mate Series fittings are engineered for automotive fluid service and are widely recognized in both OEM replacement and performance modification markets. The three-way configuration eliminates the need for multiple single-port connectors, reducing joint count and potential leak points in complex cooling architectures. Verify hose inner diameter and material compatibility with your coolant type before installation to ensure optimal seal and longevity.
