Re: MY RAZAN HOSE!!!
Dunno if this will work for a razan hose, but it worked for my jeep window plastic... Leave it out to warm up in the sun. Or put hot hot water through it a bunch. When they shipped me new jeep rear windows they were all bent and had huge creases... the heat from leaving it out in the sun for a day let the plastic become much more flexible. Creases went away. Same principle with the hookah hose plastic. It is just an idea, no confirmation from me on whether it works. just dont overdo it and somehow melt a nice hose like that.
