Smc Pneumatics KQ2T07-00A Union Tee Fitting 1/4 in Od 145 Psi

Product Description

The SMC PNEUMATICS KQ2T07-00A is a push-to-connect union tee tube fitting designed for pneumatic and fluid line installations. It accepts 1/4-inch outside diameter tubing and handles a maximum working pressure of 145 psi. The fitting body is constructed from brass with polybutylene components, providing reliable sealing without the need for thread sealants or specialized tooling. Tubing inserts and locks with a single push, and a collar release allows quick disconnection when needed. This type of fitting is commonly specified by pneumatic system technicians, HVAC mechanics, and industrial plumbers who need fast, repeatable connections in compressed air or compatible fluid circuits.

The KQ2T07-00A union tee is suited for residential and light commercial pneumatic control lines, compressed air distribution networks, and fluid transfer applications where operating temperatures range from 23 degrees F to 140 degrees F. Its three-port tee configuration allows a single supply line to branch into two outlet runs, making it practical for manifold-style tubing layouts or split-circuit pneumatic controls. It is sold and packaged as a single fitting per unit.

Key Features

• Push-to-connect design allows tool-free tube insertion and collar-release disconnection
• Accepts 1/4-inch OD tubing for a secure, leak-resistant fit
• Rated to 145 psi maximum working pressure
• Brass and polybutylene construction resists corrosion in compressed air and compatible fluid service
• Operating temperature range of 23 degrees F to 140 degrees F
• RoHS compliant materials

Compatibility

Designed as an OEM-style union tee fitting for pneumatic and fluid tubing systems using 1/4-inch outside diameter tubing at pressures not exceeding 145 psi.

Installation Notes

Installation is performed by pneumatic system technicians or licensed plumbers depending on the application. Before servicing any fitting, depressurize and isolate the affected circuit completely. Ensure tubing is cut cleanly and squarely with no burrs before insertion, as irregular cut ends can compromise the internal seal. Verify that the tubing material and system fluid are compatible with brass and polybutylene components before installing.
