Midland Industries 20013A 1/2 in Push-to-connect Plug

Product Description

The MIDLAND INDUSTRIES 20013A is a push-to-connect plug fitting used to cap off open 1/2-inch push-to-connect ports in fluid or pneumatic systems. Constructed from polypropylene, this plug is rated to a pressure class of 125 psi and provides a secure, tool-free seal. It is a practical solution for temporarily or permanently terminating unused branch lines, manifold ports, or open fittings during service or installation work. Plumbers, HVAC technicians, and pipefitters are the typical installers. Its lightweight polypropylene construction makes it well suited for applications where corrosion resistance and chemical compatibility matter.

This plug is intended for use with 1/2-inch push-to-connect tubing systems in residential and light commercial plumbing, HVAC hydronic circuits, and pneumatic distribution lines. The push-to-connect design allows fast, hand-installed termination without soldering, threading, or compression tools. It fits into any standard 1/2-inch push-to-connect fitting port and is commonly used when capping branch tees, manifolds, or staged piping runs during phased construction or system modification.
