Midland Industries SS5406-P-16 Hex Pipe Plug 1 in Mpt

Product Description

The MIDLAND INDUSTRIES SS5406-P-16 is a hex head pipe plug designed to seal threaded pipe openings in high-pressure and high-temperature fluid and gas systems. Machined from 316 stainless steel, this plug delivers strong corrosion resistance in aggressive environments including chemical, marine, and industrial applications. It features a 1-inch male pipe thread (MPT) connection with a 1-11/2 thread size and is rated for a maximum operating pressure of 4400 psi and temperatures up to 1000 degrees F. Plumbers, pipefitters, and industrial maintenance technicians install this plug to cap off unused pipe ports or branch outlets during system commissioning or modification.

This hex pipe plug is suited for residential and commercial plumbing, industrial piping systems, and process equipment where corrosion resistance and high-pressure integrity are required. The external hex head allows installation and removal with a standard wrench, making it practical in tight or recessed port locations. Typical applications include capping open tees, crosses, and manifold ports in steam, hydraulic, gas, and liquid service lines.

Installation Notes

Installation is typically performed by licensed plumbers or pipefitters following applicable IPC and ASME B31 piping codes. Depressurize and isolate the system fully before removing or installing any pipe plug. Apply an appropriate thread sealant or PTFE tape rated for the service conditions before threading the plug into the port. Tighten using a properly sized wrench on the hex head - do not use pipe wrenches on the body.
