Smc Pneumatics KQ2L12-00A Push-to-connect Union 12mm 145 Psi

Product Description

The SMC PNEUMATICS KQ2L12-00A is a push-to-connect union tube fitting designed for quick, tool-free connections in pneumatic and fluid transfer lines. Constructed from brass with polybutylene components, it handles a maximum working pressure of 145 psi and operates across a temperature range of 23 degrees F to 140 degrees F. The union configuration joins two tubes of equal outside diameter in a straight-line connection. This fitting is installed by plumbers, pipefitters, and pneumatic system technicians in both light industrial and commercial service applications.

The KQ2L12-00A is suited for 12mm outside diameter tubing in compressed air, pneumatic control, and compatible fluid distribution systems. Its push-to-connect design allows fast field assembly and disassembly without fittings tools, making it a practical choice for panel builders, OEM equipment lines, and maintenance technicians who need reliable inline connections in tight service cycles.

Compatibility

Designed for use with 12mm outside diameter tubing in pneumatic and compatible fluid transfer systems. Verify media and pressure compatibility with system requirements before installation.

Installation Notes

Installation is typically performed by pipefitters, pneumatic technicians, or qualified maintenance personnel. Depressurize and isolate the line completely before installing or removing any push-to-connect fitting. Ensure tubing is cut cleanly and squarely, and that the tube outside diameter is within the specified tolerance before insertion. Confirm all connections are fully seated and pressure-test the assembly before returning the system to service.
