Nibco I024250 Dwv Adapter 1-1/4 in Hub X Fipt Abs

Product Description

The NIBCO I024250 is an ABS (Acrylonitrile Butadiene Styrene) drain, waste, and vent adapter designed to transition between a hub connection and a female iron pipe thread (FIPT) connection in DWV piping systems. Sized at 1-1/4 inches, it handles the hub-to-threaded transitions common in residential and light commercial drain and vent rough-in work. The fitting is rated for a working temperature range of -40 degrees F to 180 degrees F and is manufactured under ISO 9001:2008 quality standards. Licensed plumbers and pipefitters install this fitting as part of ABS DWV assemblies in new construction and retrofit applications.

This adapter is suited for drain, waste, and vent piping in residential and light commercial construction. It serves hub-to-FIPT transition points where an ABS pipe or fitting must connect to a female-threaded fitting or fixture inlet. The NPTF thread standard ensures a reliable seal at the threaded connection. Typical applications include lavatory drain assemblies, vent stack transitions, and branch drain connections where a threaded port is required.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/4 inch ABS DWV piping systems using hub and female iron pipe thread connections per NPTF standards.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local code. Shut off the water supply and drain the system before cutting into an existing DWV line. Hub connections are solvent-welded using ABS-compatible cement following the fitting and cement manufacturer application instructions. FIPT connections require an appropriate thread sealant rated for plastic fittings — do not use sealants that can degrade ABS material.
