According to the duravent technical support, I can connect my liner T directly to the class A pipe inside the chimney, with a bolt/nut drilled through all walls of the class A. Have you heard of this? Also I can only get my T about an inch or so into the class A, would that be good enough? I would have to cut my T down
Can anyone recommend a SS liner 15' with T

That maybe possible, I have never done it, but I would want at least a few inches in. It sounds like it would make for an awkward installation process. This is why 7" class A was suggested.
Let's start again. What parts do you currently have? Do you have the class A thimble in addition to the short section of class A pipe?

No thimble yet. The one I linked before connects between 2x4s I believe, so I would need a different kind? I have the chimney liner kit, 6" class A double wall pipe and regular double wall pipe for the inside.If going off the duratech tech guys advice, I could connect the T to the class A prior to installing the liner, connect the T to the liner, then mortar the class A in. Also my class A section is 18" the crock currently in the wall is 12"

It sounds like a 12" section of class A would have been sufficient, but once the thimble is installed it will help hold the leveraged weight of the 18". Getting this installed, mortaring the class A in place while temporarily supporting the class A, then installing a thimble all sounds complicated as heck. I would not have chosen this method and have never tried it so I will defer to anyone who has done it.
We have both posted options for an insulated thimble to pass through a combustible wall. The class a will probably work but it is way more complicated and difficult than just using the products designed for your application.
