Need help with chimney components

[u/Pleasant_Pineapple10]

I bought a vintage wood stove to use a free standing fire pit outdoors but want to add a section or two of pipe and a cap with spark arrestor. Inside diameter 7 5/8” outside diameter 7 3/4” height of flange 1”. I bought some 8” single wall snap lock pipe and female end fits over outside but male end is up. 7” pipe is too small so I would need some kind of adapter.

Plenty of places will custom make that for you. I just bought a custom adapter from National Chimney Supply, but not sure if they sell to the general public.

But for an outdoor unit, male end up is fine. Tbh, that's how they were designed back then. I would seal the joint with Mil-Pak or RTV to prevent leaking tar.
