    AI Overview
    A 54mm toilet cistern gasket is typically a flush valve seal, often used to stop leaks in Opella Torbeck Variflush units or as a TOTO flush valve seal. These rubber or silicone rings are critical for preventing water from trickling into the pan. Key options include specific replacement 54mm washer seals and broader 80mm OD / 54mm ID gaskets for TOTO, as seen on this Amazon link. 
    Key Considerations for 54mm Cistern Gaskets: 
    • Opella Torbeck Variflush Seal (54mm): Used to fix leaks at the bottom of the flushing mechanism. These are sometimes listed as 54mm OD/28mm ID or similar variants depending on the specific model.
    • TOTO Flush Valve Gaskets: Silicone seal rings often with a 54mm inner diameter (ID) and an 80mm outer diameter (OD), compatible with models like THU440-A.
    • Key Identification: Worn gaskets cause toilets to leak, with water running into the pan constantly.
    • Material: Generally made of durable rubber or silicone for a tight seal.

    Are there different sizes of toilet seals?
    An error has occurred. Please try again later.
    Is a wax or waxless toilet seal better?
    In the end, the right choice depends on your preference. Each of the rings are equally capable of keeping water from leaking out of the base and damaging your floors. If you need wax ring replacement, talk with your plumber.
