Nibco CC03800 2 in Poly Schedule 80 Hex Plug Male Npt

Product Description

The NIBCO CC03800 is a Schedule 80 polypropylene hex plug used to close off open male NPT pipe ends in plastic piping systems. Rated for Schedule 80 service, this fitting provides a robust, chemically resistant seal in applications where standard PVC or metal fittings are not suitable. The male NPT thread engages directly with a female-threaded fitting or port. At 0.38 pounds, it is lightweight and easy to handle. Plumbers and pipefitters install this plug during pressure testing, system shutdown, or permanent port closure. The black polypropylene construction resists corrosion and many common chemical exposures.

This hex plug is suited for residential and commercial plumbing, chemical processing lines, and industrial piping systems where polypropylene material compatibility is required. The 2-inch size fits standard 2-inch female NPT ports. A hex head profile allows installation and removal with a standard pipe wrench or adjustable wrench without damaging the fitting body. It is commonly used in Schedule 80 thermoplastic systems alongside CPVC and polypropylene valves, fittings, and pipe.

Installation Notes

Installation and removal should be performed by a licensed plumber or qualified pipefitter. Shut off and depressurize the system completely before installing or removing any threaded plug. Apply thread sealant or PTFE tape rated for plastic fittings to the male threads before engagement. Do not overtighten polypropylene fittings with power tools, as plastic threads can crack under excessive torque.
