heres my problem i have an osburn 1600 freestanding wood stove. i have one piece of single wall black pipe, crimped at the end as my stove pipe that goes up from my stove to my class a adapter on the ceiling. it fits well on the class a adapter which is jsut strait pipe. on the other hand the piece that goes in to the stove is a different story. i have been burning for a month or two the way it is and it realy isnt a problem much but where the pipe seam and crimp at the bottom interset it leaves a gap where it goes in to the stove. it is only a few thousandths of an inch but when i damper it down over night some time smoke comes out. i have also noticed i get small amounts of ash over everything all around the stove after a few days from the gap. it fits tightly other wise and is screwed in well top and bottom. i dont want to seal it with rtv because i take the screws out and slide the pipe up the class a adapter to get in the top of the stove when i clean it. what should i do. is there a special adapter for this that has the sealing ridge even all the way around or is this all i get. i cant remeber who makes it but i bought it at the same place i bought my selkirk class a so i would guess it is selkirk if they even make it. other wise simpson.
 
There are two ways to handle that. One for looks and the other for ease if the stove isn't in a showplace in the house. The first way is to just push a dap of furnace cement into the gap. It is no problem at cleaning time because it gets brittle when heated so a tap with a screwdriver will bust it for taking the pipe apart. The second, unsightly, way is to put a stainless steel hose clamp around the pipe with rope gasket all the way around under it over the seam that is leaking and tighten it down. Even if you use a stove adapter that gap is just going to be in the top of it instead of the top of the stove. I hate those pipe seams.
 
all the fancy stuff they have for everything from the ceiling up and thats the best there is just plugging it with cement. its not above me i was just wondering if there was a better way. i guess not though.
 
Is there a shoulder just above the crimp? Could you cut a little off the crimp end so that the shoulder sits on the collar? It might make for a better seal. Or would the pipe itself fit into the collar if you cut above the shoulder?
Just a couple of ideas, not sure if either would work.
