Smc Pneumatics KQ2L08-00A Push-to-connect Union Fitting

Product Description

The SMC PNEUMATICS KQ2L08-00A is a push-to-connect union tube fitting designed for quick, tool-free joining of two tube runs in pneumatic and fluid-handling systems. Constructed from brass with polybutylene components, it accepts tubing with an 8mm outside diameter and is rated for a maximum working pressure of 145 psi. The fitting is suitable for compressed air, inert gas, and compatible fluid lines. Licensed plumbers, pipefitters, and pneumatic system technicians install this type of fitting in both production and maintenance applications where fast, reliable tube connections are required.

The KQ2L08-00A is well suited for residential, commercial, and light industrial pneumatic plumbing where inline tube unions are needed. Its push-to-connect design allows technicians to complete connections without additional tools, cutting installation time on air lines, water lines, and similar low-pressure tubing runs. The operating temperature range of 23 degrees F to 140 degrees F covers most indoor and climate-controlled environments. This fitting is commonly installed in automation panels, HVAC control pneumatics, and plumbing rough-in work involving polybutylene or compatible soft tubing.

Compatibility

Designed as an OEM-style push-to-connect union fitting for use with 8mm outside diameter polybutylene and compatible tubing in pneumatic and fluid-handling systems.

Installation Notes

Installation is performed by pipefitters, pneumatic technicians, or licensed plumbers depending on the application. Before servicing any line, depressurize the system fully and confirm pressure has bled to zero before disconnecting or inserting fittings. Ensure tubing is cut cleanly and squarely with no burrs before inserting into the push-to-connect collet to achieve a proper seal. Follow applicable codes such as the IPC or equipment manufacturer guidelines for pneumatic plumbing installations.
