Briggs Genuine B4484SL Flush Valve Seal. This seal is rubber. Therefore it prevents leaks through the flush valve. This seal goes inside of the dual flush valve. Also we carry the flush valve and the part number is BA2419. This seal goes inside of that valve. Therefore it will not let water go through without being flushed. Once the button on top is pushed it causes a flush. 

Also, this seal stops the valve from leaking, but it also lets the valve lift easier. Once a seal starts to wear out it swells up. Due to the fact that it sits in water. Therefore it can start to stick and make it harder to flush. However this seal will replace the old one and make it flush like new. Also, this seal is a genuine Briggs part.

In conclusion, the Briggs B4484SL Flush Valve Seal fits the 4488, and the 4484 tanks. Therefore it replaces the dual flush valve seal you have. If it is leaking into the bowl, it is the seal. However, it can also affect how easy it is to flush. Therefore the seal is rubber. Which allows it to seal.
