Sloan Flushometer Tailpiece O-Ring

This o-ring fits into a groove on the flushometer tailpiece. The tailpiece with the o-ring then slides into the control stop, where the o-ring creates a watertight seal. It is recommended that you replace the o-ring each time you loosen the connection. The o-ring needs to be replaced over time due to continuous usage and wear and tear. Breakage of the o-ring may cause the toilet to stop working properly.
