Smc Pneumatics KQ2H03-32N Push-to-connect Fitting 10-32

Product Description

The SMC PNEUMATICS KQ2H03-32N is a push-to-connect tube fitting connector designed for use in pneumatic plumbing systems. It accepts tubing with a 5/32 inch outside diameter and threads into a 10-32 UNF port. The body is constructed from brass with a polybutylene tube-contact element, and the fitting is rated for a maximum working pressure of 145 psi. This type of inline connector is a standard component in compressed-air circuit assembly, instrument air lines, and light industrial pneumatic systems. Installation requires no tools at the tube connection point - the tube seats and locks by pressing straight in.

This fitting is suited for residential and light commercial pneumatic applications where 5/32 inch OD tubing meets a 10-32 UNF threaded port. Typical use cases include control panel air lines, solenoid valve manifold plumbing, and instrument tubing runs. The operating temperature range of 23 degrees F to 140 degrees F covers most indoor and conditioned-space pneumatic environments. This part ships individually and carries a minimum order quantity of one unit.

• Accepts 5/32 inch OD tubing
• Rated to 145 psi maximum working pressure
• Brass body with polybutylene tube-contact element for durability and compatibility with standard pneumatic tubing
• RoHS compliant

Compatibility

Designed as a standard inline push-to-connect connector for pneumatic systems using 5/32 inch OD tubing and 10-32 UNF threaded ports.

Installation Notes

This fitting is installed by pneumatic technicians or qualified maintenance personnel. Before servicing any pneumatic line, depressurize the system fully and lock out the compressed-air supply. Thread the fitting into the receiving port by hand first, then tighten with an appropriate wrench - do not overtighten brass threaded fittings into soft or aluminum port bodies. To release the tube, press the collet ring inward while pulling the tube out; never force the tube out without releasing the collet, as this can damage the internal gripping teeth.
