Through MetalMitra you can source Union Tee in stainless steel, carbon steel, alloy steel, duplex, nickel alloy and other grades, across a broad range of sizes and pressure ratings.

A union tee joins three tubes of the same OD at a 90° branch.

Precision tube fittings are compression fittings that use front and back ferrules to grip the tube and form a leak-tight seal without welding, flaring or threading the tube. They are used on instrumentation, hydraulic, pneumatic, sampling and analyser lines.
