Smc Pneumatics KQ2L03-00A Push-to-connect Union Fitting

Product Description

The SMC PNEUMATICS KQ2L03-00A is a push-to-connect union tube fitting designed for fast, tool-free inline connections in pneumatic tubing systems. Built from brass and polybutylene, this union fitting accepts tubing with a 5/32 inch outside diameter and is rated for a maximum working pressure of 145 psi. It is intended for use in compressed air and pneumatic fluid control circuits where a reliable, repeatable inline connection is required. Licensed pneumatic system technicians, mechanical contractors, and automation technicians typically install this type of fitting during panel builds, machine assembly, or field service work.

This fitting is suited for light industrial and commercial pneumatic applications where push-to-connect convenience reduces installation time on tubing runs. The union configuration allows two lengths of tubing to be joined inline without threading or soldering. It performs within a temperature range of 23 degrees F to 140 degrees F, making it appropriate for standard indoor pneumatic systems in manufacturing, process automation, and HVAC control circuits. Single-piece packaging makes it easy to stock as a replacement or spare fitting.

Key Features

• Push-to-connect design allows tool-free tube insertion and secure inline union connection
• Rated for 145 psi maximum working pressure
• Accepts 5/32 inch OD tubing
• Brass and polybutylene construction for durability in pneumatic service
• Operating temperature range of 23 degrees F to 140 degrees F
• RoHS compliant

Compatibility

Designed as an OEM-style replacement or supplemental union fitting for pneumatic tubing systems using 5/32 inch OD tubing operating within the rated pressure and temperature limits.

Installation Notes

Installation is typically performed by pneumatic system technicians or mechanical contractors. Before servicing any pneumatic line, depressurize the system completely and verify pressure has been relieved before inserting or removing tubing. Ensure tubing is cut cleanly and squarely to achieve a proper seal in the push-to-connect collet. Do not exceed the rated maximum working pressure of 145 psi or the maximum temperature of 140 degrees F.
