The Spiraflex hose is made by Goodyear and there are web pages. It is  pretty 
pricey to use for a penstock but it is good to use for initial alignment  and 
coupling of a small diversion to the rigid penstock, or where a  flexible 
pipe for a siphon may be required. There are several other brands that  are 
cheaper but with a similar design.
