The MIDLAND INDUSTRIES 20762P is a plastic push-to-connect reducer fitting designed to transition between two different tube sizes in pneumatic or fluid-handling lines. Side one accepts a 3/16-inch outside diameter tube via push-to-connect, while side two connects to a 3/8-inch stem. The fitting is rated for pressures between 100 and 230 psi and is constructed entirely of plastic, making it well suited for low-corrosion and weight-sensitive applications. Plumbers, HVAC technicians, and general mechanical contractors install this type of reducer wherever two mismatched line sizes must be joined quickly without threaded tools.
This reducer is used in residential and light commercial installations where push-to-connect fittings are preferred for speed and serviceability. Typical applications include pneumatic control lines, water supply connections, and instrument tubing runs. The push-to-connect end allows for tool-free tube insertion, while the stem end slides over compatible tubing for a secure mechanical connection. Its compact plastic construction keeps weight minimal at 0.01 pounds.
Designed as an OEM-style replacement or new-installation fitting for plastic push-in plumbing and pneumatic systems using 3/16-inch push-to-connect and 3/8-inch stem connections.
Installation is typically performed by a licensed plumber or HVAC technician. Before servicing any line, depressurize the system completely and shut off the fluid or air supply upstream. For push-to-connect ends, ensure tubing is cut cleanly and squarely with no burrs before inserting to achieve a proper seal. Verify the fitting pressure rating is compatible with the operating conditions of the system before use.
