Smc Pneumatics KQ2H16-00A Push-to-connect Union Fitting

Product Description

The SMC PNEUMATICS KQ2H16-00A is a push-to-connect union straight tube fitting designed for fast, tool-free connections in pneumatic and fluid transfer systems. Built from brass with polybutylene components, this fitting handles a maximum working pressure of 145 psi and is rated for temperatures from 23 degrees F to 140 degrees F. The straight union configuration connects two tube runs inline without threading or ferrule compression, reducing installation time on both new plumbing runs and field repairs. It is a standard choice for licensed plumbers and pneumatic system technicians working on air lines, water lines, and similar low-to-medium pressure applications.

This fitting is suited for residential and light commercial pneumatic or fluid distribution systems where 16mm outside diameter tubing is used. The push-to-connect design allows a technician to complete a secure inline union simply by inserting the tube ends into each port. It is commonly installed in compressed air distribution, water supply runs, and industrial pneumatic circuits. The compact overall length of 42.20mm keeps the fitting low-profile in tight spaces or bundled line runs.

Key Features

• Push-to-connect design requires no tools for tube insertion, reducing labor time
• Rated to 145 psi maximum working pressure for pneumatic and fluid service
• Brass body with polybutylene construction resists corrosion in air and water service
• Operating temperature range of 23 degrees F to 140 degrees F suits most indoor pneumatic environments
• Straight union configuration joins two 16mm OD tube ends inline
• RoHS compliant materials

Compatibility

Designed as an OEM-style replacement or direct-install union fitting for pneumatic and fluid systems using 16mm outside diameter tubing.

Installation Notes

Installation is typically performed by a licensed plumber or qualified pneumatic systems technician. Before installing or removing the fitting, depressurize and isolate the line completely. Cut tubing square and remove any burrs before inserting into the fitting ports to ensure a reliable seal. Verify that the connected tubing outside diameter matches the 16mm specification before final installation.
