I’m trying to figure out a tape to use on the joints for that black chimney pipe? I’ve tried some foil tape McMaster and Carr had it didn’t last long, I’ve used silicone in the past but not a fan of it, if it wouldn’t be for having to take it a part I’d weld regular elbows in but I don’t want to have to cut everything a part.

How come you’re looking to seal your joints Bob? Are you getting smoke or creosote coming out?

Seems like I’m getting a little smoke especially during start up when the pipe is still cold, also it does seem to run better when they’re sealed.

Got it. I don';t have any helpful suggestions, i was just curious.

Stove collar is female ,may need the double male there then all males up and females down . Blessings and clean air and heat .

I changed things to make that happen so it’s always sucking that’s what weird.

Did you check to see if the flue is obstructed, might not be drawing right.

Yeah, unless something happened in the last couple weeks it was clear and it was doing this before.

Is your outside pipe above the roof peak? Sounds like you don’t have enough draw. Woodstoves are typically set up so the males are down so any soot or creosote runs into the stove and not out the joints. Coal stoves are opposite so they don’t leak any fumes.

I had some stuff tha came in a call tube that dried hard like ceramic. It worked for a while but broke up and fell off
It was years ago and I dont remember anything else about it. It was when I put my first wood stove in when I always about 19. and thought I would need it. turned out I didn't.
May be work for you but would.ne re done each season.

has it always had this issue? before I redid the stove pipe at my rental house smoke would come in when I opend the wood stove when we got a south wind. It was the way the air moved over the roof. when I re did it I made the stove pipe taller to draft better and it fixed it.

I had a gap in my outdoor boiler chimney cap that the pipes stack on so I just lined the outer rim of the cap with metal tape and that fixed the leak, the temp was climbing higher then in the past when shutting down at peak temp settings.

A silicone tape will work. It is called self sealing silicone tape. It is stretchy, there is no adhesive to worry about and seals/sticks to itself.

3M flue tape, good to 600deg F.
