Does anyone know where I could buy like 25ft or more of just the bare SS Flex hose 3/8" or so, like what is used on the Prommy.. I have been using the SS gas appliance hoses that Lowes and Homedepot sales, but was wondering if there is any place that sales the stuff in a large role without the flare ends? I have googled the net with no luck, any help is appreciated.

Thanks in advance.
