Smc Pneumatics KQ2T12-00A Union Tee Fitting 145 Psi

Product Description

The SMC PNEUMATICS KQ2T12-00A is a push-to-connect union tee fitting designed for pneumatic and fluid-handling tubing systems. Built from brass and polybutylene, it accepts tubing with a 12 mm outside diameter and supports a maximum working pressure of 145 psi. The push-to-connect design allows for tool-free tube insertion and secure retention without threading or compression ferrules. This fitting is installed by pneumatic technicians, pipefitters, and plumbing professionals in industrial and commercial environments where quick, reliable tube connections are required.

This union tee is suited for pneumatic control lines, instrumentation tubing, and light fluid conveyance applications where a three-way branch connection is needed. Its operating temperature range of 23 degrees F to 140 degrees F makes it appropriate for standard indoor industrial environments. The RoHS-compliant construction supports use in facilities with environmental material restrictions. An overall length of approximately 2.29 inches keeps the fitting compact within tight panel or manifold layouts.

Compatibility

Designed as an OEM-style push-to-connect fitting for pneumatic tubing systems using 12 mm outside diameter tubing in industrial and commercial installations.

Installation Notes

Depressurize and de-energize all lines before removing or installing any push-to-connect fittings. Confirm tubing outside diameter matches the 12 mm rated size and that tube ends are cut cleanly and squarely to ensure a proper seal. Do not exceed the 145 psi maximum working pressure rating during operation or testing. Installation should be performed by a qualified pneumatic technician or pipefitter in accordance with applicable facility and system codes.
