I have been using Silicone Radiator Hose for some of these hoses. While I realise that they may not be Approved, as Joel notes, where I need to remove these occasionally these are a godsend. Like me, they have no memory, and are simple to remove. With that in mind, I always use two good quality SS Clamps on them. For me, the only downside is that they are pricey, but there is a local Hose Vendor that has pretty good prices. I wouldn't use these for a major suction purpose.
