If you begin to experience these, it's time to think about replacing them.HomeSaver White Gasket Rope - 1/2" x 84" is easy to install. Simply remove the old, worn, frayed gasket, clean the surface, and glue in a new gasket with stove gasket cement. It is braided, not coiled, so it is not easily unraveled.
