Union Tee

A Union Tee is a precision-engineered instrumentation tube fitting designed to connect three tubes of the same outside diameter (OD), allowing fluid or gas flow to be divided or combined within a hydraulic, pneumatic, or instrumentation system. It features three compression tube ends arranged in a tee configuration, providing a secure, leak-proof, and vibration-resistant connection without the need for welding or threading.

Union Tees are widely used in process control systems, instrumentation panels, hydraulic circuits, and pneumatic applications where a branch connection is required. The double ferrule compression design ensures excellent grip on the tubing and provides reliable sealing under high-pressure and high-temperature operating conditions. Its compact and robust construction simplifies piping layouts, reduces installation time, and enhances system efficiency.

Manufactured using premium-quality raw materials and advanced CNC machining technology, our Union Tees offer exceptional dimensional accuracy, excellent corrosion resistance, superior mechanical strength, and long service life. Every fitting is produced in accordance with international standards and undergoes stringent quality inspections to ensure dependable performance in demanding industrial environments.

Available in a wide range of tube sizes, pressure ratings, and material grades, our Union Tees are trusted across industries for safe, efficient, and reliable fluid and gas distribution systems.
