Midland Industries 62639MS Hex Head Plug 2-1/2 in Npt Ss 150 Lb

Product Description

The MIDLAND INDUSTRIES 62639MS is a cored hex head plug designed for sealing pipe ends in pressurized fluid and gas systems. Built from 304 stainless steel, it connects via a 2-1/2-inch male NPT thread (2-1/2-8 thread series) and carries a 150 lb pressure class rating. The cored hex head design allows standard hex wrench engagement for installation and removal. This fitting is commonly installed by licensed plumbers, pipefitters, and HVAC technicians working on commercial and industrial piping systems where corrosion resistance and media compatibility are required.

This plug is rated for use with air, water, oil, natural gas, and steam media, making it a versatile choice across plumbing, HVAC, and process piping applications. The 304 stainless steel construction provides reliable corrosion resistance in both wet and dry environments. It conforms to ASME B1.20.1 dimensional standards, ensuring consistent thread form and fitment across standard NPT pipe systems. Typical installations include capping branch outlets, deadheading unused tee ports, and temporary or permanent pipe end closures in 2-1/2-inch lines.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC and IFGC code requirements for the media type involved. Depressurize and isolate the pipe section before installing or removing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before makeup. Do not overtighten; use a properly sized pipe wrench or hex wrench to achieve a snug, leak-free connection without damaging the fitting body.
