Copperfit 1A1896 Abs Dwv Closet Flange 4x3 in Hub

Product Description

The COPPERFIT 1A1896 is a 4 x 3 inch hub-style closet flange manufactured from ABS (acrylonitrile butadiene styrene) for use in drain, waste, and vent (DWV) systems. The flange connects a toilet to the drainpipe below, providing a stable mounting base for the toilet and a sealed transition into the drain line. The hub configuration accepts pipe inserted directly into the fitting for solvent-welded joints. This fitting is installed by licensed plumbers during new construction or fixture replacement work where an ABS DWV system is present.

This closet flange is suited for residential and light commercial plumbing applications where ABS DWV piping is the system material. It is used when setting or resetting a toilet on a floor-mounted drain rough-in. The 4-inch top collar accepts a standard wax ring and toilet bolt slots, while the 3-inch hub connects to the existing drain stack or branch line below the floor.

Key Features

• Hub-style inlet accepts 3-inch ABS pipe for solvent-welded connection
• 4-inch collar provides standard toilet mounting interface for wax ring and closet bolts
• ABS construction offers resistance to common household drain chemicals
• Designed for use in DWV systems — not rated for pressure service
• Single-piece molded body simplifies installation and reduces potential leak points

Compatibility

Designed as an OEM-style replacement or new-installation fitting for residential and light commercial ABS DWV closet drain applications with a 3-inch drain line and a standard 4-inch toilet flange rough-in.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and local authority having jurisdiction (AHJ) requirements. Shut off the water supply and evacuate the drain line before removing or replacing an existing closet flange. Use the appropriate ABS solvent cement and primer for the hub joint; do not substitute PVC cement on ABS fittings. Confirm flange height relative to finished floor elevation before securing to ensure a proper wax ring seal.
