Midland Industries 44662 Cored Square Head Plug 4 in Mpt Bronze

Product Description

The MIDLAND INDUSTRIES 44662 is a cored square head plug designed for use in bronze pipe fitting systems where a threaded male pipe connection must be capped or blanked off. The plug features a 4-inch MPT (male pipe thread) connection conforming to ASME B1.20.1 thread standards and carries a 125 lb pressure class rating. The square head drive profile accepts a wrench for installation and removal. Built from bronze, this plug is suited for water distribution, plumbing, and related fluid-handling applications. Licensed plumbers and pipefitters are the typical installers for this type of fitting.

This plug is used in residential and commercial plumbing systems, water distribution lines, and industrial piping where a durable bronze fitting is required. The cored design allows for future use of the port if needed. At 4 inches MPT, this is a large-diameter plug appropriate for main line or high-flow branch capping applications. It meets multiple dimensional and performance standards including AWWA C800, ASME B16.15, and MSS-SP-106, making it appropriate for municipal and commercial water system work.
