Oatey OA43651 Straight Open Replacement Closet Flange 4 Inch Pvc Domestic

Product Description

The Oatey OA43651 is a straight open replacement closet flange designed for residential and commercial plumbing repairs. A closet flange, also called a toilet flange, is the fitting that connects the base of a toilet to the drain pipe below the floor. When an existing flange cracks, corrodes, or breaks, replacing it restores a secure and leak-free connection between the toilet and the waste line. The OA43651 is built from durable PVC plastic, which resists corrosion, moisture, and the chemical exposure common in drain line environments. This makes it a reliable long-term solution for toilet installations and repair work. The straight open design means the flange sits level and allows direct access to the drain opening, simplifying installation and alignment. It fits a 4 inch inside diameter and accommodates a 4 inch pipe, which is the standard size used in most residential toilet drain applications. Plumbers and contractors will find this flange straightforward to work with on new installs or replacement jobs. The white PVC construction blends cleanly with standard subfloor materials and is compatible with common PVC cement and primer systems. Domestically produced, this replacement flange meets the quality standards that professional plumbers rely on for consistent, code-compliant work. Whether you are repairing a failed flange in a bathroom remodel or replacing a damaged fitting during a rough-in, the OA43651 delivers the fit and function needed to get the job done right. It is suitable for use in both residential new construction and repair applications where a standard 4 inch toilet drain flange is required.

• Straight open design allows easy toilet-to-drain alignment during installation and replacement
