Smc Pneumatics KQ2R10-12A Plug-in Reducer Fitting 145 Psi

Product Description

The SMC PNEUMATICS KQ2R10-12A is a push-to-connect plug-in reducer tube fitting designed to connect tubing of two different outside diameters in pneumatic plumbing systems. 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 push-to-connect mechanism allows for tool-free tube insertion and secure, leak-resistant connections without threading or soldering. This fitting is suited for compressed air and pneumatic fluid transfer lines where a fast, reliable reducer connection is required.

The KQ2R10-12A is used in industrial and commercial pneumatic systems where tubing diameter transitions are needed inline. The 10mm outside diameter tube port reduces to a 12mm stem outside diameter, making it appropriate for routing compressed air lines through equipment assemblies, control panels, and automation systems. It is typically installed by industrial maintenance technicians, pneumatic system integrators, and mechanical contractors working with push-to-connect tubing networks.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion and removal
• Brass construction with polybutylene components for durability in pneumatic service
• Rated to 145 psi maximum working pressure
• Operating temperature range of 23 degrees F to 140 degrees F
• RoHS compliant construction
• Compact overall length of approximately 1.54 inches (39.20mm) for tight installations

Compatibility

Designed as an OEM-style push-to-connect reducer fitting compatible with 10mm outside diameter tubing on one end and a 12mm stem on the other, suitable for standard pneumatic tube fitting applications within the rated pressure and temperature limits.

Installation Notes

Installation is performed by pneumatic system technicians or mechanical contractors. Depressurize and lock out the pneumatic system before removing or installing fittings. Verify tubing outside diameter matches the fitting port specification before insertion to ensure a proper seal. Inspect tubing ends for squareness and burrs prior to insertion, as damaged tube ends can compromise the connection seal.
