Rebuilding a Rex flushometer to stop leaks and restore a clean flush, this 3.5 gpf washer set supplies the seals, washers, and diaphragm parts that wear out inside a Rex 107 closet flushometer and cause it to run on, under-flush, or leak. Over time the rubber and leather sealing parts harden, tear, or clog with debris; replacing the full set in one service renews the valve instead of chasing one bad part at a time. Matched to the Rex 107 valve and the 3.5 gpf flush volume, the genuine parts seat and seal correctly for a proper rebuild. It is the correct-fit kit for servicing a Rex 3.5 gpf flushometer on a toilet.
