Merit Brass 118-32 Brass Countersunk Plug 2 in Mnpt Fnpt

Product Description

The MERIT BRASS 118-32 is a brass pipe countersunk plug rated for Class 125 service, designed to close off threaded pipe openings in plumbing, HVAC, and industrial piping systems. The plug features male NPT (MNPT) external threads and a female NPT (FNPT) countersunk recess, allowing it to sit flush or recessed within a fitting when installed. At 2 inches fitting size, this plug suits mainline and branch shutoff applications where a clean, low-profile termination is required. It weighs 1 pound and is constructed from brass, offering reliable corrosion resistance in water and low-pressure piping applications. Licensed plumbers and pipefitters are the typical installers.

This countersunk plug is suited for residential and light commercial piping installations where threaded pipe ends must be capped or blanked off. Common applications include capping unused tee outlets, sealing branch connections, and closing off test ports in potable water, hydronic heating, and general-purpose fluid systems. The 2-inch fitting size accommodates standard Schedule 40 threaded pipe. The Class 125 pressure rating makes it appropriate for low-to-moderate pressure service lines.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off and depressurize the system before removing or installing any threaded plug. Apply thread sealant tape or pipe dope appropriate for the service fluid before threading the plug into the fitting. Tighten to hand-tight plus wrench turns as appropriate for threaded brass fittings per standard trade practice, and pressure-test the connection before returning the system to service.
