Bsc Preferred 4410 Heavy Duty Wax Bowl Gasket

Product Description

The BSC PREFERRED 4410 is a heavy-duty, urethane-reinforced wax bowl gasket designed to create a watertight seal between a toilet bowl and the floor or wall drain flange. The extra-thick urethane construction delivers up to 20 times the strength of standard wax gaskets, resisting compression failure and permanent deformation over time. The integrated No Seep sleeve extends into the waste line, adding sealing depth and reducing the risk of bypass leaks. Licensed plumbers install this gasket during toilet setting or bowl replacement as part of standard rough-in work.

The 4410 fits 3-inch and 4-inch drain lines and is compatible with most wall-mounted and all floor-mounted toilet bowls. The gasket accommodates up to 0.5 inches of tolerance in rough-in measurement and bowl setting height, making it well-suited for installations where the flange sits slightly above or below the finished floor. It is appropriate for both residential and light commercial toilet installations.

Key Features

• Urethane-reinforced construction — up to 20 times stronger than standard wax gaskets
• Extra-thick profile provides added compression and sealing depth
• No Seep sleeve extends bowl outlet into the waste line for enhanced seal integrity
• Resilient material flexes with bowl movement without breaking the seal
• Will not rot, deteriorate, or compress permanently like fiber or sponge alternatives
• Accommodates up to 0.5 inches of rough-in and bowl-setting tolerance

Compatibility

Fits 3-inch and 4-inch drain lines. Compatible with most wall-mounted and all floor-mounted toilet bowls. Suitable as an OEM-style replacement wax gasket in residential and light commercial toilet installations.

Installation Notes

Installation is performed by a licensed plumber. Shut off the water supply, flush and empty the tank and bowl, and disconnect the supply line before removing the existing toilet. Remove all old wax residue from the flange and horn before setting the new gasket. Set the gasket onto the bowl horn or flange per local IPC requirements, and lower the bowl straight down without rocking to seat the wax evenly. Do not lift and reset the bowl once it has contacted the gasket, as this breaks the seal.
