I finally got all the parts (hopefully) I need to install a glue liner in a masonry chimney. I went with DVL stove pipe and Duraflex liner. Since I’m going through a combustible wall to the chimney I purchased an insulated wall pass through: https://www.northlineexpress.com/6-duraliner-wall-pass-through-6dlr-wpt-6052.html . I also purchased the duraflex tee with cap: https://www.northlineexpress.com/6-duraflexss-tee-with-cap-6dfs-t-6573.html to connect to this. It does state that it connects to duraliner tee but not duraflex. Did I get the wrong part or can I simply crimp the tee and have a safe setup? Also, in the wall pass through should I do something to seal the gap inside (pictured)? I could not find anything through my research or through the duravent installation manuals for this setup. Thanks in advance!

Yes you got the wrong part
 
So which part do I need. the duraliner tee? If that is the case, will flex liner connect directly to it? Because it states that it is for duraliner products.
You need a different insulated thimble. Just one for a standard liner
 
The DuraLiner pass through is specific to the DuraLiner system.
Something like this is required.
