Midland Industries 44653D Cored Square Head Plug 1/2 in Mpt

Product Description

The MIDLAND INDUSTRIES 44653D is a cored square head plug designed to close off 1/2-inch male pipe thread (MPT) openings in bronze piping systems. Rated at 125 lb pressure class, this fitting is manufactured from bronze, making it well suited for water, gas, and fluid distribution applications where corrosion resistance and durability are required. The cored design provides a recessed center that allows for future service or connection without full removal of the plug. At 0.95 inches in length, it is a compact, reliable fitting used by licensed plumbers and pipefitters working in both residential and commercial systems.

This plug is intended for use in bronze fitting assemblies on water service, distribution, and related piping systems. The 1/2-14 thread specification conforms to ASME B1.20.1 standards, ensuring compatibility with standard NPT-threaded pipe and fittings. It is commonly installed in situations where a branch or outlet must be temporarily or permanently sealed while leaving the option to core out the plug later for future use. The 125 lb pressure class rating makes it appropriate for general service piping within typical residential and light commercial operating pressures.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IPC guidelines. Shut off and depressurize the piping system fully before installing or removing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before installation to ensure a leak-free seal. Do not overtighten, as bronze fittings can be damaged by excessive torque.
