Midland Industries 620600CA Straight Union 3/8in Ptc

Product Description

The MIDLAND INDUSTRIES 620600CA is a straight union fitting designed for push-to-connect installation in compressed air and fluid transfer lines. Both ends accept 3/8-inch push-to-connect tubing, allowing fast, tool-free connections without threading or soldering. The composite body construction meets D.O.T. standards, making it suitable for demanding transport and industrial plumbing applications. It carries a rated working pressure of 145 psi and operates across a temperature range of -40 to 140 degrees F. Licensed plumbers, HVAC technicians, and fleet maintenance professionals install this fitting in pneumatic and fluid line assemblies where quick, reliable unions are required.

This fitting is used in residential and commercial applications involving push-to-connect tubing systems, including compressed air lines, pneumatic control circuits, and fluid distribution assemblies. The D.O.T. composite body designation makes it appropriate for use in mobile and transport equipment plumbing as well as stationary systems that require lightweight, corrosion-resistant fittings. It is a straight union configuration, meaning it joins two lengths of tubing inline without changing direction or reducing size.

Key Features

• Push-to-connect on both ends for tool-free installation and removal
• 3/8-inch connection size on each port for inline union joining
• Composite body construction meets D.O.T. standards
• Rated working pressure of 145 psi
• Temperature range of -40 to 140 degrees F for broad service conditions
• Straight union configuration maintains tubing direction and bore size

Compatibility

Designed as an OEM-style replacement or new-installation fitting for push-to-connect tubing systems using 3/8-inch outside diameter tubing in D.O.T.-compliant composite body applications.

Installation Notes

Shut off and depressurize the line completely before removing or installing any push-to-connect fitting. Ensure tubing ends are cut square and free of burrs before insertion to achieve a proper seal. This fitting is installed by licensed plumbers, HVAC technicians, or qualified maintenance professionals familiar with pneumatic and fluid plumbing systems. Verify that tubing material and system pressure are within the rated limits of the fitting before placing the line back in service.
