Gaskets are used on 0s to create an air-tight seal between parts or materials that flex at different and unequal rates during the heating and cooling process. For example; steel absorbs heat very quickly and it will expand as it gets hotter; glass absorbs heat slowly and does not expand very much. Gaskets are used between these materials to create a seal between your door and door glass. Gaskets on your 0 should be replaced every couple of years to every year, but it really depends on how much you use your 0.
