|I'm not 100% positive which part(s) you're talking about.
Can you be a little more specific and descriptive of the hose and which ends and so forth, and which goes over which.
Also, what do you mean by "crease"? Is it a cut at all, or just a bend?
Without the above info, I'm just guessing, but an inside coupler might do the trick, might not, depends on what part is going over what part, and whether the inside coupler restricts flow too much.
Let me know!
