Smc Pneumatics KQ2H01-34NS Push-to-connect Fitting 1/8 Npt

Product Description

The SMC PNEUMATICS KQ2H01-34NS is a push-to-connect tube fitting in a straight connector configuration. It accepts 1/8-inch OD tubing and threads into a 1/8-inch NPT port, providing a fast, tool-free tube connection in pneumatic plumbing systems. The body is brass with a polybutylene collet, rated to 145 psi maximum working pressure. Operating temperature range runs from 23 degrees F to 140 degrees F, making it suitable for indoor compressed-air service in light industrial and commercial environments. Pneumatic technicians and maintenance mechanics install this fitting when routing tubing to valves, cylinders, sensors, or manifolds.

This fitting is used in compressed-air distribution and pneumatic control circuits where quick tube insertion and removal are needed without sacrificing pressure integrity. It is appropriate for residential automation panels, commercial HVAC pneumatic controls, and light industrial automation lines. The NPT thread allows direct installation into standard pipe-threaded ports on valves, fittings, and equipment bodies. Typical tubing materials compatible with push-to-connect collet fittings of this type include polyurethane and nylon tubing at the specified OD.

Key Features

• Push-to-connect design allows tool-free tube insertion and one-touch release
• Brass body construction for corrosion resistance and durability in compressed-air service
• 1/8-inch NPT male thread for direct installation into standard pipe-threaded ports
• Rated to 145 psi maximum working pressure
• Wide operating range from 23 degrees F to 140 degrees F
• RoHS compliant

Compatibility

Designed as an OEM-style replacement or new-install push-to-connect connector fitting for pneumatic systems using 1/8-inch OD tubing and 1/8-inch NPT threaded ports.

Installation Notes

Depressurize the pneumatic circuit completely before removing or installing any fittings. Apply thread sealant or PTFE tape to the NPT threads in accordance with applicable plumbing and pneumatic codes before threading into the port. Insert tubing straight and fully into the collet until it seats to ensure a leak-free connection. Do not exceed the 145 psi rated working pressure or the 140 degrees F maximum temperature in service.
