Oatey – Stainless Steel Closet Flange Replacement Ring

The Oatey 42778 Stainless Steel Closet Flange Replacement Ring is a durable toilet flange repair part designed to restore a secure toilet connection when the original metal flange ring is broken, rusted, or corroded. Built from corrosion-resistant stainless steel, this replacement ring is made for long-lasting performance in bathroom plumbing repairs, remodels, and toilet installations. It fits standard 3 inch and 4 inch toilet flanges, making it a practical solution for residential and commercial plumbing service work.

This ring is installed over or in place of a damaged toilet flange ring to create a secure mounting surface for the toilet. The installer removes the toilet, cleans away the old wax, assesses the flange damage, fastens the replacement ring to the floor through the countersunk holes, places a new wax ring, then resets the toilet. Oatey’s toilet flange repair guide notes that the right repair depends on flange condition, and damaged or low flanges may require repair rings, spacers, or replacement depending on the situation.
