Midland Industries 63658MS 2in Mpt Square Head Plug 316 Ss

Product Description

The MIDLAND INDUSTRIES 63658MS is a cored square head plug designed for threaded pipe systems requiring a reliable, corrosion-resistant closure. Built from 316 stainless steel, this plug features a 2-inch male pipe thread (MPT) connection with a 2-11-1/2 thread specification and is rated for a 150 lb pressure class. The square head drive allows installation and removal with a standard wrench or pipe wrench, making it practical for tight service environments. This fitting is manufactured to SP-114 standards and is suited for plumbing, process piping, and industrial fluid handling applications where 316 stainless steel is specified for its enhanced resistance to chlorides and corrosive media.

This plug is commonly installed in commercial and industrial piping systems where a dead-end closure on a 2-inch threaded female port is required. Typical applications include process lines, marine environments, chemical handling systems, and food-service or sanitary installations where 316 stainless steel is preferred over 304. Licensed plumbers and pipefitters install this fitting during new construction, system modification, or maintenance work on 150 lb-rated threaded pipe systems.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 2-inch female NPT threaded ports in 150 lb-rated piping systems requiring 316 stainless steel construction.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable IPC or IFGC codes. Depressurize and drain the system before removing or installing any threaded pipe plug. Apply an appropriate thread sealant or PTFE tape to the male threads before installation. Do not overtighten; use a calibrated torque wrench where required by system specifications.
