Smc Pneumatics KQ2R11-13A Push-in Reducer Fitting 3/8 in

Product Description

The SMC PNEUMATICS KQ2R11-13A is a push-to-connect plug-in reducer tube fitting designed for pneumatic and fluid-handling plumbing systems. It accepts 3/8 inch OD tubing on the push-in side and features a 1/2 inch stem outside diameter, allowing field technicians to quickly transition between two different tube sizes without tools. Constructed from brass and polybutylene, the KQ2R11-13A is rated to 145 psi maximum working pressure and handles temperatures from 23 degrees F to 140 degrees F. The push-to-connect design speeds up assembly and reduces the risk of connection errors during installation.

This fitting is suited for compressed air and low-pressure fluid lines in both light industrial and commercial applications. It is typically installed in pneumatic control panels, equipment plumbing manifolds, and process lines where a fast, reliable tube-size reduction is needed without threading or soldering. Maintenance technicians and industrial plumbers working on pneumatic equipment and compressed air distribution systems are the primary installers of this type of component.

Key Features

• Push-to-connect design allows tool-free tube insertion and release
• Reduces from 1/2 inch stem OD to 3/8 inch OD tube in a single fitting
• Rated to 145 psi maximum working pressure
• Operating temperature range: 23 degrees F to 140 degrees F
• Brass and polybutylene construction for corrosion resistance in pneumatic service
• RoHS compliant

Compatibility

Designed as an OEM-style push-to-connect reducer fitting for pneumatic tubing systems using 3/8 inch OD tube connections.

Installation Notes

This fitting is installed by qualified pneumatic technicians or industrial plumbers. Depressurize and isolate the line completely before removing or inserting any push-to-connect fitting. Ensure tubing is cut cleanly and squarely, with no burrs, before insertion to maintain a proper seal. Verify the system operating pressure does not exceed the 145 psi rating of this fitting.
