I use Spiralite 170, milk hose. I get it from Eastern Crown Inc. in Vernon, NY. It is food grade and rated from -10 to +130 F. They sell it by the foot and the price is good. Fast shipping too, same day if you order before noon. Likely other dairy supply vendors sell it too.

I use left over chunks of mainline.1.5" for the ro and 1.25" for the submersible extractor

If you can go to 2 inch, your local milk hauler will have used 2 inch milk hose that they have to discard. Very flexible in cold Temps and it's free. Usually in 33 foot lengths.
