Available in diaphragm only and Royal Performance Kits. Royal Performance Kit includes dual filtered diaphragm assembly, handle repair kit with triple seal packing, high back pressure vacuum breaker repair kit, and one tailpiece O-ring. Diaphragm Only KIT contains drop-in dual filtered diaphragm assembly ONLY.
The dual filtered diaphragm can be used in Royal, Regal, and similar diaphragm-style valve bodies. For use in Sloan valve bodies with a bell-shaped cover (manufactured before 1964), replace the bottom filter ring in these kits with a blue A-108 Filter Ring.
Note the smaller of the two diagrams: the colors of the relief valve and the refill head plus the shape of flow ring identify the flush volume of a Dual-Filtered Diaphragm Assembly.
