Nibco I177250 Dwv Plug 2 Inch Mipt Abs Fitting

Product Description

The NIBCO I177250 is an ABS (Acrylonitrile Butadiene Styrene) plug fitting designed to cap off 2-inch drain, waste, and vent (DWV) lines using a male iron pipe thread (MIPT) connection. This fitting is manufactured to ISO 9001:2008 quality standards and is suited for use in residential and light commercial plumbing rough-in work. Licensed plumbers install this plug to pressure-test DWV systems, permanently seal unused branch openings, or cap stub-outs during staged construction. The lightweight ABS construction and standard MIPT thread pattern make installation straightforward with no special tooling beyond a pipe wrench or channel-lock pliers.

This plug is intended for use in non-pressure DWV piping systems where ABS plastic is an approved material per the applicable plumbing code. Typical applications include capping 2-inch branch tees, cleanout openings, and test ports in residential drain lines, as well as sealing vent stack openings during rough inspection. It is not rated for potable water supply or pressurized service lines.

Key Features

• ABS construction rated for service from -40 degrees F to 180 degrees F
• 2-inch MIPT connection threads directly into female-threaded DWV fittings
• Lightweight at 0.06 pounds — minimal load on plastic fittings during installation
• ISO 9001:2008 quality standard compliance
• Single-piece molded construction with no gaskets or separate components to lose

Compatibility

Designed as an OEM-style replacement or new-installation plug for 2-inch female iron pipe thread (FIPT) openings in ABS DWV piping systems where threaded plastic plugs are permitted by the applicable plumbing code.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter working on a drain, waste, and vent system. Shut off or isolate the affected drain line before installing or removing this plug, and ensure the system is not under any test pressure before removal. Hand-tighten first, then snug with a strap wrench or pipe wrench — avoid overtightening, which can crack ABS threads. Check local plumbing codes (IPC or UPC as adopted) to confirm ABS threaded plugs are approved for the specific application.
