Smc Pneumatics KQ2H03-34AS Push-to-connect Fitting 1/8 Npt

Product Description

The SMC PNEUMATICS KQ2H03-34AS is a push-to-connect tube fitting connector designed for quick, tool-free tubing connections in pneumatic and fluid-handling systems. Built from brass with a polybutylene component, it accepts 5/32 inch outside-diameter tubing and threads into a 1/8 inch NPT port. The fitting is rated to 145 psi maximum working pressure and operates across a temperature range of 23 degrees F to 140 degrees F. RoHS-compliant construction makes it suitable for installations with environmental material restrictions. Licensed plumbers, pipefitters, and pneumatic system technicians typically specify this type of fitting for instrumentation, control, and process-line applications.

This connector is intended for use in pneumatic tubing circuits, light fluid-handling lines, and instrumentation systems where a fast, reliable push-to-connect interface is required. The 1/8 inch NPT thread is a standard port size found on valves, manifolds, solenoids, cylinders, and similar components across residential, commercial, and light industrial equipment. It is particularly useful in situations where service frequency or tight installation spaces make traditional compression or barbed fittings impractical.

Compatibility

Designed as a standard push-to-connect NPT connector compatible with 5/32 inch OD pneumatic tubing and any component or panel with a 1/8 inch NPT port. No specific model or system compatibility data was provided by the manufacturer for this SKU.

Installation Notes

Installation is typically performed by a licensed pipefitter, pneumatic technician, or instrumentation specialist. Depressurize the system completely and verify zero pressure before removing or installing any fitting. Apply thread sealant or PTFE tape to the NPT threads in accordance with applicable piping codes. Confirm tubing is cut cleanly and squarely before insertion to ensure a proper seal within the collet.
