As requested Toilet flapper

grabcad

A toilet flapper is an essential component of a flush valve assembly in a toilet tank, designed to control the flow of water during flushing and prevent leakage when the tank refills. It consists of a rubber or plastic disc attached to a chain that lifts it off its seat, allowing water to flow through the flush valve and into the bowl. Once the flush is complete, the flapper falls back onto its seat, sealing the valve and stopping the flow of water.
