Midland Industries 44638LF Countersunk Plug 2 in Mpt Bronze

Product Description

The MIDLAND INDUSTRIES 44638LF is a square drive countersunk plug designed to seal threaded pipe openings in pressurized plumbing systems. Machined from lead-free bronze, this plug features a 2-inch male pipe thread (MPT) connection with a 2-11-1/2 thread form and carries a 125 lb pressure class rating. At 0.8 inches in length with a 0.85-inch socket size, it fits flush or recessed into fittings and pipe ends. Licensed plumbers and waterworks contractors install this type of plug during system commissioning, repairs, and pressure testing where a clean, low-profile closure is required.

This countersunk plug is suited for residential and commercial potable water systems, irrigation lines, and general waterworks applications where lead-free compliance is required. Its bronze construction holds up in both wet and dry service conditions. The square drive recess accepts a standard square bit or driver, making installation practical in tight spaces where a wrench-flat plug would be difficult to turn. It ships with a minimum order quantity of one piece, making it available as a single replacement fitting.

Installation Notes

Installation is performed by a licensed plumber. Shut off and depressurize the water system before removing or installing any threaded plug. Apply an approved thread sealant or PTFE tape to the male threads before hand-tightening, then snug with a square drive bit - avoid over-torquing bronze fittings as they can crack under excessive force. Work must comply with applicable local plumbing codes and AWWA or ASME standards as required by the jurisdiction.
