Inquiry (采购产品): product? I am looking for telescopic tubing that I can run a cathater through for housing or sheath an retract on a weekly average. The inner flex tube will carry water. I was thinking it would have to be metal but plastic might work. Does such a product already exist, if so what lenght and diameter are they? Thank you, perry21991@aol.com **** Hidden Message ***** andrea perry 83687 USA Company: independent E-mail: perry21991@aol.com **** Hidden Message ***** perry21991@aol.com
