Nibco I178500 Dwv Plug 6 Inches Mnpt Abs Fitting

Product Description

The NIBCO I178500 is a 6-inch male NPT (MNPT) plug designed for drain, waste, and vent (DWV) piping systems. Molded from acrylonitrile butadiene styrene (ABS), this fitting is used to terminate or temporarily cap a threaded DWV line. The MNPT connection threads directly into a female-threaded fitting or pipe end. It handles a temperature range of -40 degrees F to 180 degrees F, making it suitable for standard residential and commercial drain and vent applications. Licensed plumbers and pipefitters are the typical installers. Manufactured under ISO 9001:2008 quality standards.

This plug fits into 6-inch female NPT-threaded DWV pipe or fittings in residential and commercial drain, waste, and vent systems. It is commonly used during pressure testing, system commissioning, or to permanently close an unused branch on a DWV network. ABS construction keeps the fitting lightweight and resistant to common drain-line chemicals and corrosion.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off and drain the affected line before removing or installing any threaded plug. Use an appropriate thread sealant rated for plastic fittings and follow manufacturer torque guidelines for ABS threaded connections. Do not overtighten, as excessive torque can crack ABS fittings.
