A silicon gasket's primary purpose is to create a constant tight seal. Over time a gasket can dry out and lose its elasticity. If you notice this happening, replace the gasket immediately. A worn out gasket can lead to steam not building up, or worse, escaping from your cooker.

This solved the problem I was having with cooker not building steam. I was putting up with all sorts of twisting and banging to make the old one work for almost a year. Why did I not buy it then---description did not tell that it would fit my size cooker. They changed the description to explain the 9" and 10" gaskets. And they riased the price. Not to worry ---- this was the fix needed. I was ready to get a new cooker.
