Smc Pneumatics KQ2H03-00A Push-to-connect Union Fitting

Product Description

The SMC PNEUMATICS KQ2H03-00A is a push-to-connect union straight tube fitting designed for quick, tool-free connections in pneumatic and fluid transfer systems. Built from brass with a polybutylene body, this fitting accepts 5/32-inch OD tubing on both ends and handles up to 145 psi working pressure. It is suited for compressed air lines, instrumentation tubing, and light fluid distribution in industrial and commercial environments. Licensed technicians and mechanical contractors working with pneumatic control systems will find this fitting straightforward to install without specialized crimping or threading tools.

This fitting is used in pneumatic control panels, automated equipment, and process piping runs where fast, repeatable tube connections are required. Its straight union configuration allows inline splicing of same-diameter tubing runs. The operating temperature range of 23 degrees F to 140 degrees F makes it appropriate for indoor industrial and light commercial installations. It ships individually and is well-suited for maintenance, repair, and operations stock as well as new system builds.

Compatibility

Designed as an OEM-style push-to-connect union fitting for pneumatic and fluid transfer systems using 5/32-inch OD tubing, compatible with standard pneumatic control and instrumentation lines operating within the rated pressure and temperature limits.

Installation Notes

Installation is typically performed by mechanical or pneumatic technicians. Before servicing any pneumatic line, depressurize the system completely and verify zero pressure at the connection point. Ensure tubing ends are cut cleanly and squarely with no burrs before inserting into the fitting to achieve a proper seal. Verify the system does not exceed the 145 psi pressure or 140 degrees F temperature ratings during operation.
