Smc Pneumatics KQ2L16-00A Push-to-connect Union Fitting

Product Description

The SMC PNEUMATICS KQ2L16-00A is a push-to-connect union tube fitting designed for inline tube-to-tube connections in pneumatic and fluid handling systems. Constructed from brass with polybutylene contact components, this union fitting accepts 16mm outside-diameter tubing and is rated for a maximum working pressure of 145 psi. Installation requires no tools beyond hand pressure - insert the tube, and the internal collet locks and seals automatically. HVAC technicians, plumbers, and pneumatic system technicians are the primary installers. RoHS compliance confirms restricted-substance conformance for applications where material certifications are required.

This fitting is suited for residential and light commercial pneumatic lines, compressed air distribution, and compatible fluid transfer applications. The push-to-connect design makes it a practical choice for tight spaces or installations where repeat service access is expected. Operating temperature range spans 23 degrees F to 140 degrees F, making it appropriate for indoor mechanical room environments and moderate-climate pneumatic runs. It is sold individually and packaged as a single unit.

Key Features

• Push-to-connect collet design - no tools required for tube insertion
• Brass body with polybutylene construction for corrosion resistance in pneumatic service
• Rated to 145 psi maximum working pressure
• Accepts 16mm outside-diameter tubing
• Operating range of 23 degrees F to 140 degrees F
• RoHS compliant for restricted-substance requirements

Compatibility

Designed as an OEM-style push-to-connect union replacement for pneumatic and fluid handling tubing systems using 16mm outside-diameter tube.

Installation Notes

Installation is performed by pneumatic system technicians or plumbers. Before servicing any fitting, depressurize the line completely and verify zero pressure with a gauge before disconnecting. Ensure tube ends are cut cleanly and squarely - angled or burred cuts compromise the collet seal. Follow applicable compressed air system codes and local mechanical codes for line sizing and support spacing.
