Midland Industries 44654 Cored Square Head Plug 3/4 in Mpt

Product Description

The MIDLAND INDUSTRIES 44654 is a cored square head plug used to cap or temporarily close threaded pipe openings in plumbing and water service systems. It features a 3/4-inch male pipe thread (MPT) connection and is rated for a 125 lb pressure class, making it suitable for low- to medium-pressure water and gas distribution applications. The square head drive allows installation and removal with a wrench or square-drive socket without specialized tooling. Constructed from cast bronze, this plug resists corrosion in wet service environments and holds up in both underground and above-grade installations.

This plug is designed for residential and light commercial plumbing systems, water meter installations, and irrigation service lines where a threaded bronze fitting is required. The cored design means the plug body is not solid, which is standard for this fitting type and allows for future tapping if needed. Licensed plumbers and pipefitters typically install this fitting during new construction, service tie-ins, or shutoff and isolation work. Conformance to AWWA C800, ASME B16.15, ASME B1.20.1, WW-P-460C, and MSS-SP-106 makes this fitting acceptable on projects with strict specification requirements.

Compatibility

Designed as an OEM-style replacement or new-installation bronze threaded plug for 3/4-inch MPT pipe systems conforming to AWWA and ASME dimensional standards.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off system pressure and drain the line before removing or installing any threaded plug. Apply an appropriate thread sealant or PTFE tape to the male threads before hand-tightening, then wrench-tighten to achieve a leak-free seal without over-torquing the bronze fitting. Follow applicable IPC and AWWA standards for water service fittings in your jurisdiction.
