Oatey Company 43501 Offset Closet Flange 3 to 4 Inch Pvc

Product Description

The OATEY COMPANY 43501 is a PVC offset closet flange designed to connect a toilet to a 3-inch or 4-inch DWV drain line with a 2-inch horizontal offset. This flange is used when the toilet rough-in position does not align directly over the drain centerline, allowing the installer to shift the toilet position without relocating the drain pipe. It fits over 3-inch pipe and inside 4-inch pipe, giving the installer flexibility across common residential drain configurations. Licensed plumbers install this fitting during new construction or remodel work where standard straight flanges will not achieve the required toilet placement.

The 43501 offset closet flange is suited for residential bathroom installations where the drain stub-out falls slightly off-center from the toilet flange bolt holes. The 2-inch offset corrects misalignment between the floor drain and the toilet horn without cutting and re-routing the drain line. It is appropriate for use in standard DWV systems using 3-inch or 4-inch PVC piping, a common configuration in single-family homes and light commercial restrooms.

Key Features

• 2-inch offset allows toilet repositioning without rerouting the drain
• Fits over 3-inch pipe and inside 4-inch DWV pipe for dual-size compatibility
• PVC construction resists corrosion and chemical degradation in drain service
• Sold in packages of 12 units per case for contractor stocking

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with 3-inch and 4-inch PVC DWV drain systems in residential and light commercial applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and ensure the drain line is clear before beginning work. Solvent-weld the flange to the PVC drain pipe using approved PVC primer and cement, following manufacturer cure time before setting the toilet. Do not over-tighten closet bolts, as this can crack the flange collar.
