Nibco I026050 Dwv Adapter 1-1/2 in Spigot X Fipt Abs

Product Description

The NIBCO I026050 is a 1-1/2 inch drain, waste, and vent (DWV) adapter fitting used to transition between a spigot (plain-end) connection and a female iron pipe thread (FIPT) connection. Molded from acrylonitrile butadiene styrene (ABS) for lightweight durability and corrosion resistance, this adapter is engineered for residential and commercial DWV piping systems. It handles a working temperature range of -40 degrees F to 180 degrees F, making it suitable for standard interior drain applications. Plumbers install this fitting when joining DWV pipe runs to threaded outlets or cleanout plugs within above-ground sanitary drain assemblies.

This fitting is used in residential and light commercial plumbing systems where ABS DWV pipe connects to threaded components. Typical applications include fixture drains, sanitary waste lines, and vent stacks where a smooth spigot end must mate with a female NPT threaded fitting or accessory. It is installed above grade in interior plumbing rough-in work by licensed plumbers following applicable IPC or local plumbing code requirements.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable International Plumbing Code or local authority having jurisdiction. Shut off water supply and ensure the drain system is cleared before beginning work. ABS fittings are solvent-welded on the spigot end; use ABS-rated cement and primer appropriate for the pipe schedule. Apply thread sealant or PTFE tape to the FIPT connection before engaging threaded components to prevent leaks.
