90% furnace: venting material question
I'm wondering if anyone sees an issue utilizing a rubber plumbquik elbow in a 90% furnace vent pipe? I've attached a picture.
Specs say that this supports temp up to 140 degrees.

This will be on the direct connection to the outside of the furnace and I would like to be able to remove it (if needed) without replacing vent pipe due to it being "glued"
If this is good enough for water and can support the temp, I'm wondering why it's an issue.

Well I'm in a situation now where I need to take it apart because a technician didn't seal it properly and it's leaking water. So I had to order the gray PVC piping in the furnace to replace it since it's all glued. I'm waiting for those parts to arrive.
I figured why not just use this elbow with the clamps on it just in case I need to remove it again for whatever reason.
I don't quite understand how it's really any different than the rubber elbow that connects the inducer to the PVC exhaust in the attached picture.

All the parts inside the furnace were designed and approved to be used with that furnace.
That piece has not been approved to be used in a furnace vent system.... period.
There really is no discussion involved. If you want to use it..... go right ahead.

Understood. I've scoured the net looking for an approved material list for furnace vent and just can't seem to find it. Any pointers on where I can find such information.
Again, thanks for all the help!

Rubber 90s
I believe that is the same product used to connect the draft inducer to the 2” vent pipe, but my concern would be if it’s going to be structurally sound. Hence a pvc 90 is a better choice. I’ve been at this 30 years and would not assume it’s ok without consulting factory. There’s just too much riding on your venting system being sound.
