Smc Pneumatics KQ2H06-00A Union Straight Tube Fitting

Product Description

The SMC PNEUMATICS KQ2H06-00A is a push-to-connect union straight tube fitting designed for quick, tool-free connections in pneumatic plumbing and fluid transfer lines. Constructed from brass with polybutylene components, this fitting joins two lengths of tubing in a straight inline configuration. It accepts tubing with a 6 mm outside diameter and handles a maximum working pressure of 145 psi. Licensed plumbers, pipefitters, and pneumatic system technicians install this type of fitting in compressed air distribution, automation systems, and industrial fluid lines where fast, leak-resistant connections are required.

This fitting is suited for light industrial and commercial pneumatic systems where inline tube unions are needed without threading or soldering. It is appropriate for applications requiring RoHS-compliant components. The operating temperature range of 23 degrees F to 140 degrees F makes it compatible with typical indoor compressed air and fluid systems. Its compact overall length of approximately 1.09 inches keeps installations tidy in space-constrained plumbing or pneumatic manifold environments.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion and secure locking
• Brass and polybutylene construction for durability and corrosion resistance in pneumatic service
• Rated to 145 psi maximum working pressure
• Accepts 6 mm outside diameter tubing
• RoHS compliant for use in environmentally regulated applications
• Operating range from 23 degrees F to 140 degrees F

Compatibility

Designed as an OEM-style replacement or direct-fit union for pneumatic and fluid transfer plumbing systems using 6 mm outside diameter push-to-connect tubing.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or pneumatic system technicians. Before servicing any pneumatic line, depressurize the system completely and verify zero pressure with a gauge before handling fittings. Ensure tubing ends are cut cleanly and squarely with a tube cutter for a proper seal. Confirm the system operating pressure does not exceed the 145 psi rated maximum after reconnection.
