It will stay on if:
1. You have enough contact area (>1" has worked for me)
2. The ID of the tubing is the same, or smaller than the OD of the shaft

Chances are it will take some finger strength to get the surgical tubing on without a lubricant. Its what I have been doing for weeks.
Some teams have said they use warm water or rubbing alcohol. For whatever reason we can't get warm water in our building so I haven't been able to try it.

Now that you know, can you explain why the tubing behaves this way?
