Smc Pneumatics KQ2S10-U02A Male Connector Hex Socket Fitting

Product Description

The SMC PNEUMATICS KQ2S10-U02A is a push-to-connect male connector fitting with a hex socket drive design, used to join pneumatic tubing to threaded ports in compressed-air and fluid-control systems. Constructed from brass with a polybutylene tube-contact body, it accepts 10mm outside-diameter tubing and holds a maximum working pressure of 145 psi. The universal thread type makes it compatible across a range of port configurations without requiring a dedicated thread-form adapter. Installation and maintenance crews in industrial, automation, and light-commercial environments install this fitting to create fast, tool-free tube connections at threaded ports.

This fitting is suited for pneumatic plumbing in manufacturing lines, process equipment, and compressed-air distribution systems where push-to-connect speed is required at a male-threaded port. The hex socket on the body allows torquing with a standard hex key or socket tool, reducing the risk of grip slippage on the fitting body during installation in tight spaces. It is sold individually and is appropriate wherever a single 10mm OD tube must terminate at a threaded male connection point.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion and release
• Hex socket body enables secure wrench torquing in confined installations
• Brass construction provides corrosion resistance in compressed-air service
• Rated to 145 psi maximum working pressure
• Accepts 10mm outside-diameter polybutylene tubing
• RoHS compliant

Compatibility

Designed as an OEM-style push-to-connect fitting for pneumatic systems using 10mm outside-diameter tubing at universal-thread male port connections.

Installation Notes

A licensed or qualified pneumatic systems technician should install this fitting after depressurizing and locking out the air supply to the circuit. Use a hex key or appropriately sized socket to seat the fitting body at the port; avoid over-torquing the brass body against the mating port material. Confirm tubing is cut square and fully inserted until it bottoms out before pressurizing. Verify there are no leaks at working pressure before returning the system to service.
