Rutland E-Z Spread Fiberglass Stove Gasket Cement - 2.7 Ounce Tube

For most wood stove applications, you will want to use gasket cement as it can withstand temperatures up to 2000 degrees. Silicone-based sealants, commonly used with gas hearth systems and storm collar installation, will only withstand temperatures up to roughly 500 degrees on average and would not work well when bonding stove gaskets to steel or cast iron stove surfaces. However, some gasket kits will include a silicone-based glue that will withstand higher temperatures around 800 degrees, but these kits should only be used for their intended purpose. For example, this kit may be made specifically for replacing a window and gasket in certain manufactured wood stoves. The product literature for these models may call for window gasketing with the same dimensions and allows for lower-temperature gasket glue to be used as there is a narrow channel where both the window pane and gasket tape must fit. The gasket glue would not reach 800 degrees in this application as it would be shielded from higher temperatures and any direct flame.

Once the gasket cement has been applied and has air dried, you will need to burn a fire in the appliance in order to heat the gasket surface to the 500 degrees required for the adhesive to fully harden.
