Oatey Set-Rite Toilet Flange Extender Kit 1/4–1-5/8 in | Red & Yellow

Upgrade Your Plumbing with the Oatey Set-Rite Flange Extender Kit

The Set-Rite Toilet Flange Extender Kit from Oatey is designed for remodels and repairs when the flange sits below the finished floor. By extending the flange surface, it helps support a reliable seal with a standard wax ring and can simplify subsequent maintenance or replacement. This kit brings together practical components that make flange height management straightforward, even in challenging bathroom updates.

What you get matters in a successful install. The kit includes four spacer sizes and six self-tapping screws, giving you flexibility to match existing piping and flooring scenarios. It is compatible with common flange materials such as PVC, ABS, cast iron, and stainless steel ringed flanges, making it a versatile option for a range of homes and remodel projects.

Key features and practical benefits

• Extends the flange surface above finished flooring to support a proper seal.
• Height range: corrects flange height from 1/4 inch to 1-5/8 inch.
• Four spacers in varying sizes plus six self-tapping screws for a complete install.
• Designed to work with a standard wax ring for dependable sealing performance.

Real-world use often involves remodels where the existing flange sits too low, or flooring height changes after tile or linoleum is installed. In these cases, raising the flange surface with Set-Rite can help align the toilet base with the finished floor and simplify bolt spacing and wax-ring seating. The included hardware is intended to streamline the installation process, while the spacer options accommodate different plumbing configurations without large-scale modifications.

Brand reliability matters. Oatey has earned the trust of plumbing professionals for more than a century, and the Set-Rite line reflects that legacy with practical design and clear, straightforward installation. The red and yellow kit colors help on-site identification, while the product aims to offer a measured, non-pressured solution for flange height management. Remember that results depend on proper installation and other factors in the bathroom environment, so review fit and clearances before starting.

Tips for best results: verify flange compatibility, dry-fit components before final assembly, and follow standard wax-ring sealing practices to maintain a clean, watertight connection.
