Smc Pneumatics KQ2U05-34AS Push-to-connect Y Fitting

Product Description

The SMC PNEUMATICS KQ2U05-34AS is a push-to-connect Y-connector tube fitting designed for quick, tool-free tubing connections in pneumatic and fluid-handling systems. Built from brass with a polybutylene collet, it accepts 3/16 inch OD tubing and threads into 1/8 inch NPT ports. The fitting handles a maximum working pressure of 145 psi and operates reliably across a temperature range of 23 degrees F to 140 degrees F. Its Y-body configuration allows a single port to branch into two lines, making it a practical choice for manifolding or splitting pneumatic supply lines in compact installations. Licensed HVAC technicians, plumbers, and pneumatic system technicians are the primary installers.

This fitting is suited for light industrial and commercial pneumatic plumbing applications where 3/16 inch OD tubing must be split or joined at a single threaded connection point. Typical use cases include instrument air distribution, pneumatic control line branching, and low-pressure fluid transfer circuits. The 1/8 inch NPT thread makes it compatible with standard NPT-tapped manifolds, valve bodies, and port blocks commonly found in HVAC controls and process equipment. RoHS compliance makes it appropriate for installations with environmental material restrictions.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion and release
• Y-body configuration splits one NPT port into two 3/16 inch OD tube connections
• Brass body construction for corrosion resistance in pneumatic and fluid service
• Rated to 145 psi maximum working pressure
• Operating range of 23 degrees F to 140 degrees F suits a wide range of ambient conditions
• RoHS compliant materials

Compatibility

Designed as a direct-fit push-to-connect Y-connector for pneumatic and fluid-handling systems using 3/16 inch OD tubing and 1/8 inch NPT threaded ports.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic or fluid-handling systems. De-pressurize and lock out the system before removing or installing any fittings. Ensure the NPT threads are clean and apply appropriate thread sealant per the system requirements and applicable codes before tightening. Verify tubing is cut square and free of burrs before inserting into the push-to-connect collet to ensure a proper seal.
