Midland Industries 62639B1 Hex Head Plug 2-1/2 in Mpt Ss

Product Description

The MIDLAND INDUSTRIES 62639B1 is a barstock hex head plug designed to seal threaded pipe openings in high-pressure fluid and gas systems. Machined from 304 stainless steel barstock, this plug features a 2-1/2 inch male pipe thread (MPT) connection and is rated for service up to 1000 to 3000 psi depending on application and temperature. The hex head configuration allows for standard wrench engagement during installation and removal. At 3.93 pounds, the plug reflects the solid, full-body construction expected from barstock fittings. It is installed by licensed plumbers, pipefitters, and industrial maintenance technicians working on pressurized piping systems.

This plug is suited for use in residential, commercial, and light industrial piping systems where a threaded pipe end must be capped or blanked off. The 2-1/2 inch MPT size is common in main distribution lines, headers, and branch connections within water, steam, air, and compatible chemical service systems. The 304 stainless steel construction makes it appropriate for environments requiring corrosion resistance, including wet or chemically active service conditions. It falls within the 1000-pound and above pressure class for stainless steel fittings.

Key Features

• Machined from 304 stainless steel barstock for consistent wall thickness and pressure integrity
• 2-1/2 inch MPT connection seals standard female-threaded pipe fittings and valves
• Rated 1000 to 3000 psi for high-pressure piping applications
• Hex head design accepts standard pipe wrenches and hex sockets for secure installation
• Corrosion-resistant 304 SS construction suitable for wet and mildly corrosive service environments

Compatibility

Designed as an OEM-style threaded pipe plug for use in 2-1/2 inch female NPT fittings, valves, and pipe headers within 1000-pound and above pressure class stainless steel piping systems.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements for the service type. Depressurize and isolate the piping system completely before installing or removing any threaded plug. Apply an appropriate thread sealant or PTFE tape to the male threads before torquing into place. Do not over-tighten stainless steel fittings against stainless female threads, as galling can occur.
