2‑Pack 3‑Inch Toilet Flapper Replacement Kit – Fix Running Toilets & Ghost Flushing, Fits Most 3" Valves, Works with Kohler, TOTO & American Standard, Durable Rubber Seal

Standardized Design: We adopt a unified standard design with an appropriate size design to keep it open for a long enough time, allowing enough water to flow out of the water tank to remove solid waste from the bowl.

• 【Universal Compatibility】Designed specifically for Gerber 99‑788 and other 3‑inch flush valves. Fits standard 3" tank openings (size: 4.9" x 3.66"). A direct replacement for old, leaky flappers – stops wasted water and cuts your water bill.
• 【Durable Rubber Seal】Made from high‑quality, soft rubber that compresses and rebounds quickly for a tight, leak‑proof seal. Helps prevent constant running and saves water with every flush.
• 【Optimized Flush Performance】Meets U.S. and Canadian plumbing standards. The flapper stays open long enough for a strong, complete flush – so your toilet cleans effectively without short‑cycling.
• 【Tool‑Free Installation】Install in minutes – no special tools required. Just turn off the water, drain the tank, remove the old flapper (cut it if stuck; never force it), snap in the new one, and attach the included chain. Simple!
• 【Great Value 2‑Pack】You get two flappers – use one now and keep a spare handy. Fix leaks yourself and avoid costly plumber visits. Each pack also includes two toilet handle chains for extra convenience.
