Smc Pneumatics KQ2L13-00A Push-to-connect Union Fitting

Product Description

The SMC PNEUMATICS KQ2L13-00A is a push-to-connect union tube fitting designed for fast, tool-free inline connections in pneumatic and fluid-transfer plumbing systems. Built with a brass body and polybutylene components, this union fitting accepts 1/2-inch outside diameter tubing on both ends and holds a maximum working pressure of 145 psi. It is rated for temperatures from 23 degrees F to 140 degrees F, making it suitable for a wide range of indoor pneumatic, compressed-air, and light fluid applications. HVAC technicians, plumbers, and industrial maintenance professionals install this type of fitting where quick inline joins or replacements are needed without soldering or threading.

This fitting is appropriate for residential and light commercial pneumatic plumbing lines, compressed-air distribution systems, and fluid-transfer tubing runs where 1/2-inch OD tubing is used. Its push-to-connect design allows fast field installation in tight spaces or where repeated disconnection may be required. The union configuration makes it ideal for in-line splices and repairs on existing tubing runs.

Installation Notes

Installation is performed by qualified HVAC technicians, plumbers, or industrial maintenance personnel. Before installing or removing the fitting, depressurize the line completely and verify the system is isolated from its air or fluid supply. Cut tubing squarely and deburr the end before insertion to ensure a proper seal and prevent damage to internal collet components. Verify tubing OD matches the fitting specification before assembly.
