How stretchy is this. I need to connect 2-1/4 to 1-3/4. It looks really close.

Not very stretchy at all normally. Back when I used it and found out it was too small I boiled it for a bit and was able to stretch it a fair amount. You might have to buy a new hose clamp if you stretch it too much, but mine still held a tight seal as the plastic cooled and shrunk down onto the pipes I was connecting.

Need to connect 2" copper to 1 1/2" sch 80 pvc. will this work?

This was made to connect 1 1/2" pipe size (approx 2" OD as yours) to 2" pipe (approx 2 3/8" OD). Your 2" copper pipe/tube is approx 2 1/8" OD. So, no, it will not work as intended in your application. Tom

Will this work connecting 2" barb to a 1-1/2" barb?

This should work on barbed pipe. You may tighten the bands a little more than usual
