Smc Pneumatics KQ2H09-36AS Push-to-connect Fitting 5/16in

Product Description

The SMC PNEUMATICS KQ2H09-36AS is a push-to-connect tube fitting connector designed for quick, tool-free tubing connections in pneumatic and fluid-handling systems. Constructed from brass with a polybutylene tube collet, it accepts 5/16-inch OD tubing and threads into ports via a 3/8-inch NPT male thread. Rated to 145 psi maximum working pressure, it handles temperatures from 23 degrees F to 140 degrees F. This fitting is well suited for compressed-air lines, instrumentation tubing, and light-duty fluid circuits where fast assembly and reliable seals are required. Installation is performed by plumbers, pipefitters, and pneumatic system technicians.

The KQ2H09-36AS is used in residential, commercial, and light industrial environments where 5/16-inch OD tubing must be connected to NPT-threaded ports. Typical applications include pneumatic control panels, air preparation assemblies, process instrumentation, and general plumbing lines operating within the rated pressure and temperature envelope. The push-to-connect mechanism allows for rapid tube insertion and removal without additional tools, making it appropriate for both new installations and service work on existing systems.

Compatibility

Designed as an OEM-style push-to-connect connector fitting for pneumatic and fluid-handling systems using 5/16-inch OD tubing with 3/8-inch NPT threaded ports.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or qualified pneumatic technician. Depressurize and isolate the line before removing or installing any fitting. Apply thread sealant or PTFE tape to the NPT threads per standard practice and applicable plumbing codes before threading into the port. Ensure tubing is cut cleanly and squarely and is fully seated in the collet before returning the system to pressure.
