Can someone link me the correct reducer for my newly lined chimney thimble? Its a 4 inch liner so i need a 4 inch pipe with a 6 inch collar. Thimble is 6 inch and i basically need something to plug the gaps around pipe as it comes through thimble. Im fine with stuffing it full of fireproof insulation aswell, ive spent enough $$$ as is. But not even sure on correct insulation to use. Any help would be appreciated thanks.

6" stainless should extend out of the wall then be reduced to 4" with any 6 to 4 reducer.
I have mostly duravent from lowes, i assumed they are interchangeable but now that i think about it dura vents have tabs thet need to be lined up
Except its a 4inch stainless liner sorry if i wasnt super clear about that, only thimble itself is 6 inch. I need a 6 inch collar, that has a straight 4inch pipe in the center. But i cant find one
Oh Oops. Then just extend out with 4" stainless then pack with insulation and either mortar overthat or make a metal trim plate.
