Midland Industries Vacuum Pumps

Overview

The MIDLAND INDUSTRIES 20758P is a plastic push-in reducing union designed to join two different tube sizes in pneumatic and fluid-handling line assemblies. It connects a 1/2-inch push-in tube on one end to a 3/8-inch push-in tube on the other, allowing quick, tool-free tube insertion without fittings or ferrules. Rated for 100 to 170 psi and suitable for operating temperatures from 34 to 150 degrees F, this gray plastic union is built for air, gas, and vacuum service. Its compact form factor keeps it practical in tight spaces within control panels, pneumatic enclosures, and equipment plumbing runs. This reducing union is used in light commercial and industrial pneumatic systems, HVAC controls, automation equipment, and similar applications where different tube diameters must be joined inline. It is appropriate for air lines, inert gas distribution, and vacuum circuits operating within the rated pressure and temperature limits. Technicians working on compressed air distribution, pneumatic control tubing, or gas-handling assemblies will find this fitting a direct, low-effort connection solution. Key Features Push-in connection on both ends for tool-free tube insertion and removal Reduces from 1/2-inch tube to 3/8-inch tube in a single inline fitting Rated 100 to 170 psi operating pressure Temperature range 34 to 150 degrees F Compatible with air, gases, and vacuum service Gray plastic construction - lightweight and corrosion-resistant Compatibility Rated for use with air,…
