Compare a replacement flapper only after identifying the flush-valve opening and toilet model.

Three things to check first ↓

Manufacturer information + practical buying checks. No hands-on testing or paid rankings.

A little illustration. A real-world decision.

WHAT IT IS

The useful part.

Adjustable replacement flapper for a 2-inch toilet flush valve, supplied with a stainless-steel chain.

Based on the manufacturer information in our catalog.

LESS GUESSWORK. MORE PLAN B.

Three checks before you buy.

Confirm a two-inch flush-valve opening rather than assuming all flappers use the same size.
Check part 100 or alternate 100BP in the manufacturer’s compatibility guidance.
Read the adjustment and chain-installation directions for your toilet before choosing the setting.

Where this comes from.

The product description comes from the manufacturer material recorded in our sourced catalog. The buying checks, limitations and related-item choices are editorial guidance, not hands-on test results. Check the current model and instructions before ordering.
