Overview
A 3-inch replacement flapper for toilets with large flush valve openings, made from chlorine resistant rubber with a stainless steel chain attachment. Fits tanks needing a 3 inch seal, from a brand with a long flapper-making history.
Korky pitches this as its high performance version rather than a bargain part; the sizing is fixed at 3 inches rather than adjustable, so it targets a specific valve opening instead of a universal fit. The rubber compound and steel chain aim at the two failure points that usually end a flapper's life: chlorine breakdown and chain corrosion.
- 3 inch flush valve fit
- Chlorine resistant rubber
- Stainless steel chain
- From a 50+ year flapper manufacturer
Who it's for
Homeowners whose toilet tank uses a 3 inch flush valve and want a direct like-for-like swap rather than an adjustable universal part. Not for the more common 2 inch valve toilets found in many standard tanks.
Pros and cons
- Sized for large 3 inch flush valves
- Chlorine resistant rubber compound
- Stainless steel chain won't rust
- Fixed 3 inch size, not adjustable
- No listed water-saving dial
Performance notes
The rubber is formulated to resist chlorine, which is the compound that most commonly hardens and cracks standard flappers when tank tablets are used. A stainless chain resists the rust that causes chain links to seize or snap, a common cause of a flapper that won't seal.

Frequently asked questions
What size flush valve does the Korky 3060BP fit?
It's built for the large 3 inch flush valve opening, not the more common 2 inch size.
Will tank chlorine tablets damage this flapper?
The rubber is made to resist chlorine breakdown, which is the usual reason standard flappers crack.
Does the chain rust?
It uses a stainless steel chain attachment, so it resists the rust that causes standard chains to fail.
