Midland Industries 62637 Hex Head Plug 1-1/2 in Npt Ss 150lb

Product Description

The MIDLAND INDUSTRIES 62637 is a cored hex head plug designed to cap or close off pipe ends in threaded piping systems. It features a 1-1/2-inch male NPT connection with a 1-1/2-11-1/2 thread specification and is rated for 150 lb pressure service. Constructed from 304 stainless steel, this plug resists corrosion in demanding fluid and gas handling environments. The hex head profile allows for standard wrench installation without special tooling. It conforms to ASME B1.20.1 dimensional standards, ensuring consistent thread fit and pressure integrity across compliant piping assemblies. Plumbers, pipefitters, and mechanical contractors install this type of fitting in commercial and industrial pipe runs.

This plug is suitable for use in systems carrying air, water, oil, natural gas, and steam media, making it appropriate across a range of trade applications including plumbing, HVAC, and light industrial piping. Its 150 lb pressure class fits standard low-pressure service lines in both residential and commercial settings. The 304 stainless steel construction makes it a practical choice in wet or corrosive environments where carbon steel fittings would be prone to rust or scale buildup.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ASME standards. Shut off and depressurize the system before installing or removing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before engagement. Do not overtighten stainless steel fittings, as galling of the threads can occur.
