Closet Gasket for Toilet Tanks

The Dearborn Brass 7555 closet gasket creates a watertight seal between the toilet tank and bowl. Moulded from black rubber, it resists chlorine exposure to maintain elasticity over time. The regular-type design fits most standard toilet configurations. Supplied as a single gasket for direct installation.

Suitable for Standard Tank Repairs

This gasket suits homeowners or plumbers replacing a worn seal on a typical two-piece toilet. It is not intended for proprietary one-piece units or specialised flange connections that require a shaped or reinforced gasket. Buyers needing a universal wax ring or a bolted flange kit should look at a different product type.

Chlorine-Resistant Rubber Material

The rubber compound is formulated to withstand chlorinated water supplies without premature hardening or cracking. This material property directly determines how long the seal remains flexible and leak-free. A one-year manufacturer warranty covers defects in the gasket itself.
