Union Tee

Description & Features

Manufactured in brass, this Eaton Aeroquip Union Tee is designed for instrumentation, hydraulic, and pneumatic system applications requiring a reliable three-way tube connection. Two ends accept line or hose tubing in a 3/16 in. configuration, while the third end is a 3/8 in. male connection, making it well suited for branching or splitting fluid lines within a system assembly.

The fitting features Dura-Kote plating for corrosion resistance and is rated for operating pressures above standard SAE thresholds, providing added margin in demanding service environments. A minimum working temperature of -65°F extends its usability across a broad range of conditions. As part of the Aeroquip line, it belongs to a broad family of adapter styles offering flexibility when configuring or modifying hydraulic and pneumatic circuits.
