Water Closet Diaphragm Inside Part Kit

SPECIAL ORDER ITEM. Review Returns Policy before purchase. This genuine water closet diaphragm inside part kit is engineered to repair or replace the working diaphragm assembly in 1.6 gal-per-flush exposed closet flushometers. The kit includes both the relief valve and diaphragm components required to restore proper flushing performance, helping maintain correct flow and reliable operation after wear or service. Constructed with durable Permex rubber, it resists chloramines and other water treatment by-products better than natural rubber parts, and the dual filtered action helps reduce bypass clogging. Suitable for routine maintenance or overhaul of compatible flushometer valves to ensure efficient and consistent flush cycles.
