Midland Industries 44653 Square Head Plug 1/2 in Mpt Bronze

Product Description

The MIDLAND INDUSTRIES 44653 is a cored square head plug used to close off threaded pipe ends in plumbing, water service, and general piping systems. Machined from bronze, it threads onto a 1/2-inch male pipe thread (MPT) connection using a 1/2-14 thread specification and is rated for a 125 lb pressure class. The square head profile accepts a wrench for reliable installation and removal without slippage. At 0.92 inches in length with a 0.56-inch head size, it is a compact fitting suited for tight piping assemblies. Plumbers and pipefitters install this plug as a working or test-point closure on bronze and compatible brass fittings.

The 44653 is used in residential and light commercial water service and plumbing piping systems. It is appropriate for applications requiring compliance with AWWA C800, ASME B16.15, ASME B1.20.1, WW-P-460C, and MSS-SP-106 dimensional and material standards. Typical install scenarios include temporarily or permanently capping an unused branch outlet, isolating a section of pipe during pressure testing, or sealing a test port after commissioning.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2 in MPT bronze and brass pipe fittings in plumbing and water service piping systems conforming to ASME and AWWA standards.

Installation Notes

Installation is performed by licensed plumbers or pipefitters. Shut off and depressurize the affected pipe section before installing or removing any threaded plug. Apply an approved thread sealant or PTFE tape to the male threads in accordance with local plumbing codes before making up the connection. Do not over-tighten; wrench engagement on the square head is sufficient to achieve a pressure-tight seal without damaging the fitting.
