Oatey Company 4310 Urethane Wax Toilet Gasket with Flange

Product Description

The OATEY COMPANY 4310 is a urethane wax toilet gasket with integrated flange, designed to create a watertight seal between a toilet horn and the closet flange. Urethane wax holds its shape better than standard paraffin-blend wax under heat and pressure, reducing the risk of seal failure over time. The gasket fits 3-inch and 4-inch drain lines and seats against most floor-mount and wall-mount bowl configurations. Licensed plumbers and skilled tradespeople install this gasket during new toilet installations and toilet resets following floor work or wax seal replacements.

This gasket is suited for residential and light commercial toilet installations. It works with standard 3-inch and 4-inch drain lines, covering the most common rough-in configurations found in homes, apartments, and small commercial buildings. The built-in flange extension helps bridge minor height gaps between the closet flange and the toilet horn, providing a more forgiving installation on flanges that sit slightly below finished floor level. The 10-year guarantee reflects the manufacturer's confidence in urethane wax construction over conventional wax formulations.

Key Features

Compatibility

Designed for use with 3-inch and 4-inch drain lines and fits most floor-mount and wall-mount toilet bowl configurations in residential and light commercial applications.

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson. Shut off the water supply and fully drain the tank and bowl before removing the existing toilet. Install only once — wax gaskets are single-use and must be replaced if the toilet is reset after initial installation. Follow applicable IPC and local plumbing code requirements for closet flange height and toilet anchor bolt torque.
