Hi All, I got the 4" stainless liner installed and the T put together at the bottom that extends out of the chimney. Now, at the vertical and horizontal T connection, is there a typical way to seal this joint? Since its in a chimney I only have access to the inside of the joint shown in the picture. Thanks!
You could try a bead of RTV.... supposed to be good up to 650ºF ... if it doesn’t work, try something else... https://www.permatex.com/products/g...s/permatex-high-temp-red-rtv-silicone-gasket/
Yes, I can get my hand in there and I have some of that permatex on hand. Thanks! Sent from my iPhone using Tapatalk
I'd use the rutland rtv which is rated for higher temps. Over 1000ºF ifn I remembered correctly. Stove cement is also a good choice and rated for 2000ºF. Hard as a rock though and a b1tch to get off if you ever have too. Make sure you knead it into the joint too, Don't just smear over it.
