Value Collection 6SQ11/2 Square Head Pipe Plug 1-1/2 in 316 Ss

Product Description

The VALUE COLLECTION 6SQ11/2 is a 1-1/2 inch square head pipe plug machined from 316 stainless steel and threaded with a male NPT (MNPT) connection. It is designed to close off open pipe ends and fittings in piping systems rated up to 150 psi. The square head drive allows for positive wrench engagement during installation and removal. The 316 stainless steel construction provides corrosion resistance in wet, chemical, and marine environments. This plug is a standard threaded pipe fitting installed by plumbers, pipefitters, and industrial maintenance technicians across a wide range of applications.

This plug is suited for residential and commercial plumbing systems, industrial process piping, and marine or coastal installations where chloride exposure makes 316 stainless steel the preferred material over 304 grade. It is commonly used to cap unused tee or cross outlets, seal test ports, and close branch lines during system modifications or pressure testing. The 150 psi pressure rating covers most standard service conditions in low-pressure piping systems.

Key Features

• 316 stainless steel construction for superior corrosion resistance in harsh and wet environments
• 1-1/2 inch MNPT threaded connection for standard NPT pipe fitting engagement
• Square head drive provides secure wrench grip for installation and removal
• 150 psi pressure rating suitable for standard low-pressure piping service
• Threaded end connection for leak-free sealing of open pipe ports and outlets

Compatibility

Designed as an OEM-style replacement or standard service fitting for 1-1/2 inch NPT threaded pipe systems using 150 psi class fittings.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements. Shut off system pressure and depressurize the line completely before removing or installing any threaded pipe fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before installation and tighten with a properly sized wrench on the square head. Do not use pipe wrenches directly on the fitting body in a way that could deform the seating surfaces.
