REX DIAPHRAGM - 107-3.5 LEATHER

Restoring a smooth, complete flush to a Rex flushometer, this 107-3.5 leather diaphragm is the flexible sealing member that controls each flush cycle in a manual flush valve. The diaphragm opens to release the metered charge of water and closes to shut the valve, and when it wears, cracks, or clogs the flushometer runs on, fails to flush fully, or leaks; a fresh diaphragm restores crisp, reliable operation. Sized for the 3.5-gallon flush and made of durable leather, it matches the Rex valve for a correct rebuild. It is the correct-fit part for servicing a Rex 3.5 gpf flushometer on a toilet or urinal.

Key Features:

• Controls the Flush -- The diaphragm opens and closes the flush valve for each metered flush.
