pair of curved jaw grips usually gets them turning, then pull off, Rick

Would it be possible to warm them up a bit with an electric heat gun?

the problem is the rubber sticks to the pipe and can be very hard to shift, if round or curved jaw grips are used then there is less chance of deforming the metal pipe whilst getting maximum grip on the rubber, Rick
