Trying to figure out the brand of my appliance adapter

[Mad Tom]

Stainless steel appliance adapter for double wall pipe. Has three raised areas that slip between the inner and outer walls of the pipe so it can be screwed. Anybody have one of these?. Can't find anything similar on the net.

Simpson products have this.... Dur-Plus, Dura-Tech....

I think you're talking about this: Duravent 8674

DVL close clearance adapter. I have one that goes from the Simpson double wall to the Simpson Class A triple wall.
