    Anyone out there adapt a flex liner T through a brick chimney to Selkirk double wall stove pipe?

    I goofed up and bought a universal chimney adapter that looks to be about the same size diameter as the t snout.

    Looks like there is a masonry adapter in the catalog. Anyone have some experience with this?

    I've always ran single wall in all my setups but I am going to give this a try to improve stack temps at the end of the burn.

    Thanks to all you helpful people in advance.

    Looks like a masonry adapter is the ticket to hooking up to a t-snout for double wall. I ditched Selkirk and picked up some ICC pipe.

    Yes, run a snout a little longer than your thimble area, attach the t using the 5/16 hose clamp, add liner, then stove pipe. You can then mortar around that snout.

    Yes, I have had a t snout in the chimney for a number of years and have always run single wall.

    I'm upgrading to double wall pipe and hooking it to the stainless steel snout.

    Thought I would post this for future reference for anyone hooking double wall to a stainless steel liner.

    Follow up for anyone following this:

    I have a stainless steel t snout that I wanted to adapt to ICC double wall or Selkirk without having to crimp the stainless snout.

    Long story short, I had to crimp the stainless snout to adapt to the masonry adapter in order for it to work. My goal was to mitigate any air infiltration to the stack through loose connections.

    I wound up using refractory cement on the crimp, slid adapter over and put a band clamp over the joint.

    Moral of the story is it is easiest to use one company brand line for all chimney related parts from liner down.
