Midland Industries 44675 Square Head Plug 1in Mpt Bronze

Product Description

The MIDLAND INDUSTRIES 44675 is a solid square head plug designed to cap open male pipe thread (MPT) ports in bronze piping systems. Manufactured from bronze, this plug uses a 1-11-1/2 NPT thread on a 1 inch MPT connection and carries a 125 lb pressure class rating. The square head profile accepts a standard wrench for consistent installation torque. It is commonly installed by licensed plumbers and pipefitters working on water service, gas distribution, and irrigation systems where a durable, corrosion-resistant plug is required.

This plug is suited for residential and light commercial plumbing and mechanical systems. Typical applications include capping unused branch outlets on manifolds, temporarily or permanently sealing test ports, and blocking open tee or cross fittings during system modifications. The bronze construction makes it appropriate for potable water contact applications where corrosion resistance is a priority.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable IPC or IFGC code requirements. Shut off and depressurize the system completely before removing or installing any threaded plug. Apply an approved thread sealant or PTFE tape to the male threads before installation. Do not overtighten bronze fittings, as the material is softer than ferrous pipe and can be damaged by excessive force.
