Korky 450BP flapper for Champion 4

This Korky 450BP flapper is a direct replacement seal for American Standard Champion 4 toilets. It is made from red rubber that resists chlorine degradation. The part is designed to restore proper flush performance in compatible units. It comes new with a five-year manufacturer warranty.

Chlorine-resistant rubber reduces wear

The rubber material resists chlorine commonly found in water supplies. This resistance helps the seal maintain its shape and flexibility over time. A durable seal prevents water from leaking from the tank into the bowl. Normal use keeps the toilet operating efficiently without constant refilling.

Fits American Standard Champion 4 models

This accessory fits specifically into American Standard Champion 4 toilet tanks. No additional parts are required for installation on the correct model. Replacing a worn flapper frees the fill valve from running continuously. The repair restores normal water usage for the fixture.

Questions about this item

How is the Korky 450BP flapper installed on an American Standard Champion 4 toilet, and what step is often missed?

Turn off the water supply, flush the tank, unhook the old flapper from the flush valve posts and chain, then attach the new red rubber flapper to the same posts and reconnect the chain with just enough slack for a full seal; the step often missed is adjusting the chain length so the flapper seats completely without binding.

What maintenance or replacement will the Korky 450BP flapper need over time?

The red rubber flapper resists chlorine but will eventually degrade; plan to inspect it annually and replace it when the rubber hardens, warps or no longer forms a watertight seal, typically after several years of service.

What limit appears first on the Korky 450BP flapper during sustained use?

Continuous exposure to chlorinated water gradually breaks down the rubber compound, causing loss of elasticity and eventual leakage; this material fatigue is the first limit encountered under normal toilet operation.
