Harman CW30 Wood Stove Repair & Replacement Parts
(Gaskets)

Gaskets are used on wood stoves 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 wood stove should be replaced every couple of years to every year, but it really depends on how much you use your wood stove.
