Nibco I009250 Dwv Coupling 1-1/4 in Hub X Hub Abs

Product Description

The NIBCO I009250 is a drain, waste, and vent (DWV) coupling fitting made from acrylonitrile butadiene styrene (ABS) plastic. It connects two sections of 1-1/4-inch DWV pipe using a hub x hub end configuration, creating a straight, solvent-welded joint in residential and light commercial drain systems. The ABS construction handles a working temperature range of -40 degrees F to 180 degrees F, making it suitable for typical interior drain and vent applications. Licensed plumbers and pipefitters install this coupling as part of rough-in and repair work on gravity-flow waste systems.

This coupling is used in residential and light commercial DWV piping systems where 1-1/4-inch ABS drain or vent pipe is specified. Common applications include lavatory drain lines, vent stacks, and branch drain connections. The hub x hub socket design accepts standard 1-1/4-inch ABS pipe on both ends and relies on solvent cement to form a permanent, leak-tight joint. It is a standard catalog fitting suited to new construction rough-in and repair scenarios.

Key Features

• ABS plastic construction rated for -40 degrees F to 180 degrees F service
• Hub x hub end connections accept 1-1/4-inch ABS DWV pipe on both ends
• Straight coupling profile for in-line pipe joins and extensions
• Lightweight at 0.05 pounds, reducing handling fatigue during overhead or confined-space work
• Manufactured under ISO 9001:2008 quality management standards

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 1-1/4-inch ABS DWV piping systems in residential and light commercial plumbing applications.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes governing DWV systems. Before cutting into an existing drain or vent line, shut off water supply and confirm the line is clear of flow. Use a dedicated ABS solvent cement and primer where required by code — do not substitute PVC cement. Allow full cure time before pressurizing or flowing the system.
