Constructed from exclusive chlorine-resistant red rubber, it offers superior durability in harsh water conditions and features adjustable settings for precise water optimization.

The Korky 3060BP is a universal 3-inch toilet flapper designed for high-efficiency toilets, featuring durable red rubber resistant to harsh water conditions.
