    I figured that some here hadn't, that's why I linked to the manufacturer's info sheet. I see it occasionally around here, but I wouldn't use it myself.

    But many people go nuts when they see something they haven't before. I've seen a tech rail about how stupid hacks are going to get someone killed, it was one of those concentric adapter kits where you can run a 90%er up a regular B-vent.

    I try not to jump to "hack" right away, I haven't seen everything yet.

    That's a listed connector and flex as others mentioned. The issue is that the transite pipe is not listed and not approved for modern appliances.
