Ok I am sorry but this is sort of a pet peeve of mine when I read some of the comments here. We are talking about boats here. Just because it works in a house, car, rv, airplane. space shuttle, or whatever does not mean it will work in a boat. So many people think that marine
stuff is just high priced household stuff. In almost all cases it is not. I used to think that too but after 35 years building and repairing boats I am here to tell you that there is a difference and for good reasons.
Ok done with that rant. Sorry no do not use stainless steel it has problems with pit corrosion
and is brittle.
I will Stand by what I have said and maybe just maybe 1 person will listen and replace there copper with the correct hose and not blow up. We are talking about saving what? 20-30 bucks between hose and copper tube. Hose is easier to install and so much safer I fail to understand why so many recommend copper.
Yes copper works in refrigeration
, yes it works in steering
, but the results of failure there is not a large explosion. Twice I have stood in the middle of a small explosion due to the failure of copper tube I sort of have a strong opinion on this one. I am not going to try for number 3.
I say again use good high pressure propane rated rubber hose with proper end fittings.
