Burro gas lines

[Brad Judd]

I just renewed my old copper lines with .065 wall stainless steel and stainless compression fittings.Clamps I used had nylon inserts to reduce wear on tube when the might rub.I did a soap test when presure checked... something I may do when checking my trailer before outings.

... .065 wall stainless steel and stainless compression fittings.

If this is the system I remember, I think it would be great, and capable of handling about 1,000 times the pressure found on the regulated side of a propane system. Of course, I would want to confirm that the specific materials are appropriate for use with propane.

For several reasons the paranoia on this escapes me.

What kind of pressure are we talking about? Maybe a half a psi?

What's going to degrade the rubber? Darkness? Moisture?

On my old Scamp the original installation was copper with steel hangers. Guess what the copper looked like after 20 years around the hangers?

I ripped it all out and replaced it with rubber rated for 160 psi and gas/oil. I also installed it so nothing rubs or abrades.

As old as I am, I can guarantee you that by the time I'm finished with this Scamp the rubber will be in better shape than that old corroded green copper.

Greg-I would not be in the habit of moving that flexible metal line around very much. I think that they are meant for easy installation of permenant appliances. I would think that the proper rubber hose from the regulator to the iron pipe would be more durable.

They recommend this stuff as the way to bring the gas lines into the house and keep from damaging the gas lines in the event of an earthquake so I would imagine I'm ok. The installation using a 3 foot run of CSST flexible supply line seems much sturdier than what was there previously. I think as with anything, you need to keep an eye to maintenance for whatever type systems you use and replace if you see any indication of wear or damage.

If I were to use rubber hose for LP, here's what I would be inclined to use (says it's permeation resistant):

However, I suspect that the use of metal (iron and copper) tubing in RVs may have something to do with time-resistance to fire. Loren's right about the steel fasteners corroding after time, esp if the compartment was cleaned with bleach...
