Oatey Company 43400 Toilet Flange Extender Kit

Product Description

The OATEY COMPANY 43400 is a Set Rite Toilet Flange Extender Kit designed to correct floor elevation changes that leave an existing flange sitting below the finished floor surface. It accommodates elevation corrections from 1/8 inch up to 2-1/4 inches, making it a practical solution for remodel and renovation work where tile, hardwood, or other flooring materials have raised the finished floor above the original flange ring. The kit installs without replacing the existing flange and is listed to UPC standards. Licensed plumbers and experienced renovators are the primary installers. The patented design restores a proper sealing surface so a wax ring or gasket seal can seat correctly.

This flange extender kit is used in residential and light commercial plumbing renovation applications where the finished floor elevation has increased due to flooring installation or subfloor work. It is compatible with existing PVC, ABS, metal, stainless steel flange rings, and cast iron flanges. The kit is appropriate for repair and renovation scenarios where the goal is to restore the flange sealing surface to the correct height relative to the finished floor without full flange replacement. Each package contains 5 units.
