Midland Industries 44655 Cored Square Head Plug 1 in Mpt Bronze

Product Description

The MIDLAND INDUSTRIES 44655 is a cored square head plug designed to terminate or cap 1-inch male pipe thread (MPT) connections in bronze piping systems. The cored design allows for future tapping or blowout access without full removal, making it a practical choice for systems that may require periodic service. Built from bronze, this plug offers corrosion resistance suited to water service and related plumbing applications. It carries a 125 lb pressure class rating and conforms to multiple dimension standards including AWWA C800, ASME B16.15, ASME B1.20.1, WW-P-460C, and MSS-SP-106. Licensed plumbers and pipefitters install this fitting as part of standard bronze piping assemblies.

This plug is used in residential and light commercial water distribution, irrigation, and general plumbing systems where a bronze MPT termination is required. The 1-11-1/2 thread specification matches standard NPT taper thread used throughout North American pipe systems. Its square head profile accepts a standard wrench for reliable make-up torque without rounding. The 125 lb pressure class makes it suitable for typical domestic water pressure ranges.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off and depressurize the water supply before working on any threaded connection. Apply appropriate thread sealant or PTFE tape to the male threads per local plumbing code requirements before making up the joint. Do not over-torque bronze fittings, as the material can crack under excessive force.
