I have a house from 1978 with a sheet metal clad chimney. The old terminated flue pipe from the oil furnace and the functioning flue pipe from the wood stove protrude from the chimney's sheet metal cladding (see image).
In connection with repainting the chimney, I want to replace the two rubber boots/gaskets that seal between the flue pipes and chimney sheet metal.
The flue pipes have an outer diameter of approximately 132 and 166 mm respectively.
I suspect that the existing boots are made of a rubber/silicone blend that withstands higher temperatures. One has a stamped cutting instruction that includes the word "rökrör".
Can any knowledgeable forum member suggest where I can get heat-resistant rubber boots that fit?
