Midland Industries 62654 Square Head Plug 3/4 in Npt Ss 150 Lb

Product Description

The MIDLAND INDUSTRIES 62654 is a cored square head plug designed to close off pipe ends in pressurized systems. Machined from 304 stainless steel, it offers solid corrosion resistance in wet, chemical, and high-temperature environments. The 3/4-14 male NPT thread connects to standard female-threaded fittings and pipe bodies. Rated at 150 lb pressure class, this plug meets ASME B1.20.1 dimensional standards, ensuring consistent thread engagement with compatible fittings. It weighs 0.085 pounds and measures approximately 1.1 inches in length, 1.05 inches in height, and 1 inch in width. A licensed plumber, pipefitter, or mechanical contractor typically installs this fitting in commercial and industrial piping assemblies.

The 62654 is suited for use with air, water, oil, natural gas, and steam media, making it a versatile closure fitting across a range of trade applications. Typical uses include capping unused ports on manifolds, plugging test connections on gas lines, and closing branch openings on water distribution systems. The square head drive allows installation with a standard open-end or box wrench, which is common practice in tight spaces where a hex key or pipe wrench may not fit cleanly.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Depressurize and isolate the system completely before threading in or removing any plug. Apply an appropriate thread sealant or PTFE tape to the male NPT threads in accordance with local plumbing and mechanical codes, including IPC and IFGC requirements where applicable. Do not over-torque; tighten to the fitting manufacturer's recommended engagement depth for NPT connections.
