Smc Pneumatics KQ2H06-03AS Push-to-connect Fitting Connector

Product Description

The SMC PNEUMATICS KQ2H06-03AS is a push-to-connect tube fitting in a straight connector configuration, designed for fast, tool-free pneumatic line connections in compressed air and fluid control systems. Constructed from brass with a polybutylene tube insert, it accepts a 6 mm outside diameter tube and is rated for a maximum working pressure of 145 psi. The BSPT threaded port measures 3/8 inch. This fitting is installed by pneumatic system technicians, industrial maintenance professionals, and mechanical contractors working on compressed air distribution or fluid transfer lines.

The KQ2H06-03AS is suited for use in light industrial and commercial pneumatic systems where a reliable, leak-resistant tube connection to a threaded port is needed. It is appropriate for applications operating within a temperature range of 23 degrees F to 140 degrees F, making it a fit for both indoor climate-controlled environments and moderate-duty field installations. Typical use cases include air tool supply lines, actuator circuits, and pneumatic control panels.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion and secure retention
• Brass body construction provides durability in compressed air and compatible fluid service
• Rated to 145 psi maximum working pressure for standard pneumatic system demands
• BSPT 3/8 inch thread type for compatibility with metric and international pneumatic components
• RoHS compliant construction
• Compact overall length of approximately 0.71 inches (18.10 mm) for tight installation spaces

Compatibility

Designed as an OEM-style replacement or direct-fit connector for pneumatic systems using 6 mm outside diameter tubing with a BSPT 3/8 inch threaded port interface.

Installation Notes

Installation should be performed by a qualified pneumatic technician or industrial maintenance professional. Depressurize and lock out the pneumatic circuit before removing or installing any fitting. Verify that the mating thread type is BSPT before installation, as mixing BSPT with NPT threads can result in leaks or thread damage. Ensure the tube end is cut cleanly and squarely for proper push-to-connect engagement and seal.
