Ho do I identify tube material?
I am going to have a look at an old Northcraft and want to know if it is PVC or Hypalon. The current owner is not sure, is there an easay way to tell, or any way of finding out?

Hypalon is grey on the back, also if you sand it, it will produce dust.

I am pretty sure Northcraft are Hypalon, it has been a while since I repaired one.

It's easy to say when you know the difference but PVC is kinda smooth and plastic and slippery but Hypalon is rubbery and can be dug into with a finger nail and scratched. Not very scientific, I know. If you have a wee drop of cellulose thinners or acetone, since the Hypalon is not new, a cloth moistened and immediately wiped on a Hypalon surface will be noticeably coloured buy the surface.
