Duravent 3" stovepipe adapter

I finally received my vent kit after a mix up with the shipping but it gave me some needed time to work on the hearth. I am through the wall and everything seems to be matching up pretty well. I bought a Duravent stovepipe adapter before I received my kit because I thought I needed the extra 3" to get around a stud. I have one attached to the stove pipe and need another three inches out the house to extend the rise to the required distance from the wall. My question is has anyone ever put the adapter in line even though the adapter DOES NOT have the twist and lock notches on the male end? It seems to be a snug fit between a 1' piece and the provided cleanout and am looking to see if anyone has had exhaust escaping.

I'll post a picture of the stove because I know how you all love pictures of set-ups

Sorry I have not gotten back to this thread for awhile. For bends I only have the 45, two 90's, and a T. From the stove adapter it does to a 45 > 90> 1' section> 3" and then to the T. I have four 1' sections outside to the 90 termination. I have not had any issues with venting as of yet and calculated 20' for my EVL........ Is that borderline too high? The 3" adapter is holding very tight with the silicone and I have yet to detect any leaks after a couple weeks of use.

Yeah it was tough to not use a 45 and a 90 to exit the house because I wanted it to leave on the side rather than the front and even then I have the thimble pinned up against a stud. Thanks, I took the picture before I finished the grout but I was like a little kid on Christmas to get the stove running.
