Nibco I032200 Dwv Adapter 4 in Spigot X Mnpt Abs

Product Description

The NIBCO I032200 is a 4-inch DWV adapter fitting manufactured from Acrylonitrile Butadiene Styrene (ABS) plastic. It connects a spigot end to a male iron pipe thread (MIPT/MNPT) end, allowing a transition between plain-end ABS pipe and threaded fittings within drain, waste, and vent piping systems. The fitting is rated for a maximum working temperature of 180 degrees F and a minimum of -40 degrees F, making it suitable for typical indoor residential and light commercial DWV applications. Licensed plumbers and pipefitters install this fitting during rough-in work and DWV system assembly or repair.

This adapter is used in residential and light commercial drain, waste, and vent piping systems where a 4-inch ABS spigot connection must transition to a male NPT threaded port. Common scenarios include connecting ABS DWV pipe runs to threaded cleanout fittings, trap adapters, or other threaded components. The fitting ships individually and is suited for both new construction rough-in and retrofit plumbing work.

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 4-inch ABS drain, waste, and vent piping systems using spigot and male NPT threaded connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off water supply and verify the drain system is depressurized before beginning work. ABS fittings are typically solvent-cemented on the spigot end using ABS-rated cement; the threaded MIPT end should be assembled with appropriate pipe thread sealant rated for plastic fittings. Do not overtighten threaded connections, as ABS threads can crack under excessive torque.
