Gas lines

[Hardworking]

Has anyone replaced the copper gas lines with the yellow flex line? Need some input thanks

I believe it is not legal. The lines need to run outside the belly pan so any potential leak does not build up in the belly pan...and the flex lines would not hold up against rocks and debris. And I don't believe the flex lines are allowed inside the Airstream due to vibration issues. But I could be wrong....

I think it may be illegal because it is not a good idea. Spend the coin and go copper.

In Canada, the label on the yellow stainless steel flex lines clearly states it is not to be used in moving vehicles. Despite it being "flexible" it is not designed for continuous flexing, and will fail due to metal fatigue coming from vibration. Soft copper is much more resilient.

Also, rent or buy a good flaring tool, not a cheap $19 one.

Thank you ... I went with the copper. Everything went great, fittings etc. I just love all the help on this cite. I am 45 year old women tackling this myself. Love you guys.

I don't agree. As I recall Lewster said that Harbor Freight made a pretty good double flaring tool that was less than $20. On his recommendation, I bought one of these and it worked very well. Double flaring seems to provide a more precise flare that seals better. It worked great for me. Thanks Lewster!

You may also want to pick up a tubing bender to avoid kinks. A useful tool to have along with the flaring tool.

I stand corrected! I was thinking about the cheap ones you can buy from Menards, Home Deport, Ace, etc. I've had bad experiences with two of them, so I broke down and bought a Yellow Jacket flaring tool for about $60. Works wonderously (if that's a word). Harbor Freight does carry some pretty good tools at decent prices.

Or, a set of spring pipe benders like these: BrassCraft Tube-Bending Spring Set-T073 at The Home Depot

Just make sure to bend the pipe and remove the spring before you flare the end... That's a mistake you only make once (hopefully).
