Smc Pneumatics KQ2R03-05A Plug-in Reducer Fitting 5/32 in

Product Description

The SMC PNEUMATICS KQ2R03-05A is a push-to-connect plug-in reducer tube fitting designed for pneumatic tubing systems. It accepts a 5/32-inch OD tube and reduces to a 3/16-inch stem OD, allowing a quick, tool-free connection between two different tube sizes. The fitting is constructed from brass and polybutylene and is rated for a maximum working pressure of 145 psi. Pneumatic technicians and maintenance professionals install this fitting in compressed air lines where a compact, reliable reducer connection is needed without threaded fittings or additional tooling.

This fitting is suited for light industrial and OEM pneumatic plumbing applications where push-to-connect convenience is required. It performs within a working temperature range of 23 degrees F to 140 degrees F, making it appropriate for indoor compressed air distribution, automation equipment, and general pneumatic control circuits. Its compact overall length of approximately 1.13 inches (28.70 mm) keeps installations tight and organized in panel or manifold environments.

Compatibility

Designed as an OEM-style push-to-connect reducer fitting for pneumatic tubing systems using 5/32-inch OD tubing in compressed air and general pneumatic control applications.

Installation Notes

Installation is performed by pneumatic technicians or maintenance personnel. Before servicing any pneumatic line, depressurize the system completely and verify pressure is at zero before connecting or disconnecting fittings. Ensure the tubing end is cut cleanly and squarely for a proper seal. Do not exceed the rated working pressure of 145 psi in service.
