Smc Pneumatics KQ2R10-16A Plug-in Reducer Fitting 145 Psi

Product Description

The SMC PNEUMATICS KQ2R10-16A is a push-to-connect plug-in reducer tube fitting designed to connect tubing of two different outside diameters within pneumatic plumbing and fluid-handling systems. The fitting accepts a 10 mm tube on one end and a 16 mm stem on the other, allowing a quick, tool-free transition between tube sizes. Constructed from brass with polybutylene components, it is rated for a maximum working pressure of 145 psi and an operating temperature range of 23 degrees F to 140 degrees F. The overall length is 44.70 mm. This type of fitting is installed by plumbers, pipefitters, and pneumatic system technicians in both light industrial and commercial applications.

The KQ2R10-16A is suited for pneumatic lines, compressed air distribution, and fluid conveyance systems where tubing sizes must be reduced or stepped down inline. Its push-to-connect design eliminates the need for tools, thread sealant, or compression sleeves at the connection point, making it a practical choice for new installations and field repairs alike. The fitting meets RoHS compliance standards, making it appropriate for use in environmentally regulated environments and export applications.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion and removal
• Reduces from 16 mm stem outside diameter to 10 mm tube outside diameter in a single inline fitting
• Brass and polybutylene construction provides corrosion resistance in compressed air and compatible fluid service
• Rated to 145 psi maximum working pressure
• Temperature range of 23 degrees F to 140 degrees F suits a wide range of service environments
• RoHS compliant for use in regulated and international applications

Compatibility

Designed as an OEM-style replacement or new-install push-to-connect reducer fitting for pneumatic and fluid-handling systems using 10 mm and 16 mm outside-diameter tubing.

Installation Notes

This fitting is installed by licensed plumbers, pipefitters, or pneumatic technicians. Depressurize and isolate the affected line fully before removing any existing fitting or inserting the KQ2R10-16A. Verify that tubing ends are cut cleanly and squarely with no burrs before insertion, as irregular cuts can compromise the push-to-connect seal. Confirm system pressure does not exceed the 145 psi rating under normal or surge conditions.
