Smc Pneumatics KQ2H10-00A Union Straight Tube Fitting

Product Description

The SMC PNEUMATICS KQ2H10-00A is a push-to-connect union straight tube fitting designed for quick, tool-free connections in pneumatic plumbing and fluid-handling systems. Constructed from brass with a polybutylene body, this fitting joins two tube runs in a straight inline configuration with a rated maximum working pressure of 145 psi. The 10 mm outside-diameter tube port accepts standard metric tubing and locks in without ferrules or threading. Licensed plumbers, pneumatic technicians, and industrial maintenance crews install this type of fitting in compressed-air distribution lines and low-pressure fluid circuits.

This fitting is suited for residential and light commercial pneumatic systems, compressed-air tool circuits, and automation plumbing where fast assembly and disassembly are priorities. The union configuration makes it useful in applications requiring periodic service access, allowing either tube end to be released independently without cutting the line. It is rated for use across a temperature range of 23 degrees F to 140 degrees F, covering most indoor industrial and mechanical-room environments. The RoHS-compliant construction supports use in applications with environmental material restrictions.

Key Features

• Push-to-connect design allows tool-free tube insertion and secure locking without ferrules or compression sleeves
• Union straight configuration joins two tube ends inline for clean, low-profile routing
• Rated to 145 psi maximum working pressure for compatibility with standard compressed-air circuits
• Brass and polybutylene construction offers corrosion resistance in pneumatic and light fluid service
• Accepts 10 mm outside-diameter tubing for direct integration with metric pneumatic plumbing
• RoHS compliant for use in environmentally regulated installations

Compatibility

Designed as an OEM-style push-to-connect replacement or addition for metric pneumatic and fluid-handling tubing systems using 10 mm outside-diameter tubing rated within the 145 psi working pressure range.

Installation Notes

Shut off and bleed system pressure completely before installing or removing push-to-connect fittings. Ensure tubing is cut cleanly and squarely with a dedicated tube cutter to guarantee a proper seal at the collet. Verify tube outside diameter matches the fitting port size before insertion. This fitting type is typically installed by pneumatic technicians or licensed plumbers in accordance with applicable mechanical and pneumatic codes.
