The SMC PNEUMATICS KQ2L06-00A is a push-to-connect union tube fitting designed for pneumatic and fluid systems requiring fast, tool-free connections. Built from brass with polybutylene contact components, this union fitting joins two tubes of equal outside diameter in a straight inline configuration. It handles a maximum working pressure of 145 psi and operates across a temperature range of 23 degrees F to 140 degrees F, making it suitable for a broad range of compressed air and compatible fluid applications. Licensed tradespeople and system integrators in HVAC, pneumatic controls, and industrial plumbing regularly specify this style of fitting for its repeatable, leak-resistant connections.
This fitting is intended for use with 6 mm outside diameter tubing in pneumatic circuits, control systems, and fluid conveyance lines. It is appropriate for both light commercial and industrial installations where a reliable inline union connection is needed without threading or soldering. The push-to-connect design allows for quick assembly and disassembly during system commissioning or maintenance, reducing labor time on the bench or in the field.
Designed as an OEM-style push-to-connect union fitting for pneumatic and fluid systems using 6 mm outside diameter tubing rated at or below 145 psi working pressure.
Installation is typically performed by qualified pneumatic system technicians or licensed tradespeople. Before servicing or replacing any fitting, depressurize the system completely and verify zero pressure at the connection point. Ensure tubing ends are cut square and deburred before inserting into the fitting to achieve a leak-free seal. Verify that the tubing outside diameter and system working pressure are within the rated specifications of this fitting prior to commissioning.
