Search about copper tubing they use it for ice milt also soft copper tubing . Its just cost that gets out of hand .
Im learning as I go and far as the blue silicone heater hose they make like 3 different sizes of 1 inch . any Napa store can order it
for you as its a Eaton product . Im sure cost of the bigger 1.113 and bigger cost more but its 2 ply also . Im now reseaching best clamps to use on that blue silicone hose . really old style clamps you tighten with screw driver can cause damage . and ones you use like on a car spring style would be better they make some dam thick ones also and takes a good size pliers to get them on there .
Have any of you tried different clamps on the silicone hose ? Also I was thinking of half a flare on soft copper and sand of sharp edges.
Just a bit of a catch of the copper So the hose stays in place after clamps are on . I know there's a die for a fare tool that can used to make like smooth rounded fold . I just need to search more maybe .
