Merit 617b-32 Ss 316 Square Head Plug 2in Npt Male 3-pack

Product Description

The MERIT 617b-32 is a 316 stainless steel barstock square head plug with a 2-inch male NPT connection, sold in a package of three. Manufactured as a forged fitting, this plug is rated Class 1000 for high-pressure service and is designed with zero porosity, which eliminates the leak paths that can develop in cast fittings. It is suited for plumbing, HVAC, and industrial piping systems where a reliable, corrosion-resistant pipe termination is required. Licensed plumbers, pipefitters, and industrial maintenance technicians are the primary installers.

This fitting is used in both schedule 40 and schedule 80 threaded pipe installations where pressure integrity and long service life are critical. Typical applications include chemical process lines, potable water systems, steam lines, and high-pressure pneumatic or hydraulic piping. The 316 stainless steel alloy provides superior corrosion resistance compared to 304 SS, making it appropriate for chloride-exposed or aggressive-environment installations. Each package contains three plugs, making it practical for multi-point shutoff or system commissioning work.

Key Features

• Forged 316 stainless steel construction eliminates porosity for leak-free performance

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local codes and the International Plumbing Code. Shut down and depressurize the piping system fully before installing or removing threaded plugs. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before installation. Use a pipe wrench or socket on the square head to achieve a proper seal without over-stressing the fitting body.
