Value Collection 6SQ1 Square Head Pipe Plug 1 in 316 Ss

Product Description

The VALUE COLLECTION 6SQ1 is a 1-inch square head pipe plug machined from 316 stainless steel and designed to seal threaded pipe ends in a wide range of industrial and mechanical piping systems. The male NPT (MNPT) threaded connection provides a secure, leak-resistant fit when installed into a female-threaded port or fitting. Rated to 150 psi, this plug is suitable for moderate-pressure applications where corrosion resistance is a priority. The square head drive allows installation and removal with a standard wrench, making field service straightforward. Plumbers, pipefitters, and mechanical contractors regularly use plugs of this type to cap unused ports and terminate branch lines during system assembly or maintenance.

This plug is suited for use in residential and commercial piping systems, including water supply, process fluid, and low-pressure gas lines where 316 stainless steel is specified for its elevated corrosion resistance compared to 304 grade. Typical applications include capping tee outlets, sealing manifold ports, and blanking off test connections. The 1-inch MNPT thread size fits standard pipe fittings of that nominal diameter. This plug ships individually but is subject to a minimum order quantity of 2 units.

Key Features

• 316 stainless steel construction for superior corrosion resistance in wet, chemical, or marine environments
• 1-inch MNPT threaded connection for direct installation into standard female NPT fittings
• 150 psi pressure rating suitable for moderate-pressure piping service
• Square head drive allows installation with a standard open-end or box wrench
• Threaded seal design eliminates need for additional plug or cap hardware

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch female NPT threaded pipe connections in stainless steel piping systems rated to 150 psi.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC and IFGC code requirements. Shut down and depressurize the piping system completely before removing or installing any threaded plug. Apply an appropriate thread sealant or PTFE tape to the MNPT threads before installation to ensure a leak-free seal. Do not overtighten; use a calibrated torque approach appropriate to the fitting size and material to avoid thread damage.
