Midland Industries 44654LF 3/4 in Mpt Bronze Square Head Plug

Product Description

The MIDLAND INDUSTRIES 44654LF is a cored square head plug designed for use in water service and plumbing distribution systems. Manufactured from lead-free bronze, this plug features a 3/4-inch male pipe thread (MPT) connection and is rated for 125 lb pressure class service. The cored design allows the plug to be used as a corporation stop or service fitting entry point in potable water applications. At 0.99 inches in length with a 0.62-inch head size, it is a compact, heavy-duty fitting suited for installation by licensed plumbers and water service technicians.

This plug is intended for residential and light commercial potable water distribution, water meter installations, and service line connections where lead-free compliance is required. The 3/4-14 thread specification conforms to ASME B1.20.1 standards, ensuring consistent thread engagement with standard NPT fittings. It is appropriate for new construction and retrofit work where low-lead material requirements are mandated by local plumbing codes.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off and depressurize the water supply line before threading the plug into the fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before installation. Do not overtighten; use a properly sized wrench on the square head to achieve a secure, leak-free connection without damaging the fitting.
