Midland Industries 62633B1 Barstock Hex Head Plug 1/2 Mpt

Product Description

The MIDLAND INDUSTRIES 62633B1 is a barstock hex head plug used to cap off pipe threads in pressurized piping systems. Machined from 304 stainless steel, this plug offers corrosion resistance suited for demanding fluid and gas line applications. It features a 1/2 inch male pipe thread (MPT) connection and is rated for 1000 to 3000 lb pressure class service, making it appropriate for both standard and higher-pressure installations. Plumbers, pipefitters, and mechanical contractors install this fitting when a threaded port or branch outlet needs to be permanently or temporarily sealed. The hex head design accepts a standard wrench for proper torque without slipping.

This plug is used in residential and commercial piping installations where a threaded female opening must be sealed. Typical applications include capping unused outlets on manifolds, valves, and distribution headers in water, steam, oil, and gas systems. The 304 stainless steel construction makes it a practical choice in environments where mild corrosive exposure is a concern, such as mechanical rooms, process piping, and outdoor installations. It falls within the 1000 lb and above stainless steel fittings category and is sold in single-unit quantities.

Installation Notes

Installation of threaded pipe plugs should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC codes. Shut off and depressurize the system completely before removing or installing any fitting. Apply appropriate thread sealant or PTFE tape to the male threads before installation, and tighten to a snug, leak-free fit using a wrench on the hex head. Do not overtighten stainless steel fittings, as galling of threads can occur.
