Oatey 72035 Tank to Bowl Gasket Kit 3 and 4 Inch Waste Lines

Product Description

The OATEY 72035 is a double thick tank-to-bowl gasket kit designed to create a watertight seal between a toilet tank and bowl. Constructed from sponge rubber, the gasket compresses evenly under bolt pressure to prevent leaks at the tank-to-bowl joint. The kit includes a bolt kit with hex recess hardware, giving plumbers a complete installation package in one unit. This is a standard repair and replacement component installed by licensed plumbers and experienced DIYers during toilet service, tank replacement, or leak correction work.

This gasket kit is suited for residential and light commercial toilet installations where the waste line is either 3 inches or 4 inches. The double thick construction provides added sealing performance in situations where standard thickness gaskets have failed or where additional compression is needed due to minor surface irregularities on older porcelain fixtures. The hex recess bolt design simplifies tightening and reduces the risk of bolt spin during installation.

Key Features

• Double thick sponge rubber construction for enhanced sealing and compression
• Compatible with 3 inch and 4 inch waste line configurations
• Includes bolt kit with hex recess hardware for a complete installation
• Hex recess design prevents bolt spinning during nut tightening
• Sponge rubber material conforms to tank and bowl mating surfaces

Compatibility

Designed as an OEM-style replacement gasket and bolt kit for standard residential and light commercial toilets with 3 inch or 4 inch waste lines.

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson. Shut off the water supply to the toilet and flush to drain the tank before beginning work. Remove the old gasket and hardware, seat the new sponge rubber gasket onto the bowl horn, and lower the tank into position before hand-tightening the bolts. Alternate tightening of the tank bolts evenly to avoid cracking the porcelain, and do not overtighten.
