I'm going to fix up my Thermo Pride WC-27 wood furnace up to get through the rest of this winter and when I removed the 2 clean outs at the back of the stove, they had a gasket material between the place that you remove and the back of the furnace. The gasket disintegrated on both clean out ports and I need to replace them with something similar and safe. Any recommendations? I have come across these 2 on Amazon.
