LP supply line

[uwe]

My 71 Tradewind is getting a new LP gas lines, from the regulator on back to under the midle of the trailer. I believe it is a 5/8" copper line, with a flexible line terminating at the regulator.
Mine has so many dents and kinks that it does not seem very safe anymore.
especially the part underneath the tongue has suffered from the effects of jack stands and who knows what else.
My question surrounds the flexible line going down from the regulator to the L junction where it meets the copper line. I removed a corrugated hose, that reminds me of a gas dryer type supply line, only bigger in diameter. Is this what goes there? What do you guys use on your trailers?

John,
thanks for the suggestion. I think I read the other thread you were referring to a while back.
Is your rubber line the same diameter as the copper line? My copper line is 5/8 or 3/4, haven't measured it yet.
I took it off completely, and can not believe that propane would even still pass through it.
I am going to be looking for a rubber line like yours to go from the copper line up to the regulator. I wonder if it is readily available or if it has to be specially made?

My original connections at the regulator were also the corrogated copper. I have all new rubber hookup now, including a new auto switching regulator. The hoses are readily available and DOT approved for travel trailers. http://www.campingworld.com or any good parts stocking RV store will have them. Some states codes also require a protective shield on the regulators for new installations. About $4.00.

What I find interesting is they used copper tubing for your 71's header line under the trailer. My '65 Globetrotter uses black carbon steel pipe header with copper tubing branches to the appliances. Much stronger than tubing and less prone to damage. I have not crawled under any newer ones like yours and maybe someone else can tell us that this is the practice now. I went back with pipe, like the original.

I would not cover gas lines in any kind of foam insulation. If a gas leak occurs it will travel along the tubing or build up in the covering. The reason it is under the trailer exposed is so that you can inspect it each day during your travels and any leaks that do occur will dissipate into the air and not build up lessening the chance of explosive containment. The only place it is okay to cover is were the tubing makes penetrations into the body and this is to prevent chafing through the floor penetrations. AirStream used short little pieces of black rubber hose slid over the copper tubing.

From the regulator to main gasline (5/8") on new trailers have a LP Association approved rubber hose. Most of the new trailers have the main gas line covered with plastic water line to protect it from road damage. In the old days a corragated hose was used from regulator to main gas line. :-)

Got the same problem uwe. I bought new line from CW to replace the old corrigated line to main. There is a flair el at that end. New line doesn't fit el flair!! Can't find the right fitting. I need a reducing el, or combo of fittings. Anybody got solutions???

I went searching EVERYWHERE last week for a new line, with absolutely not even a smidgeon of luck. Home Depot, Lowe's, Camping World, Airstream, RV Repair, RV Repair, RV Repair, RV Parts, Trailer Supply - - - nothing.
It is a 5/8 flare fitting on both ends. I have a few more places to check yet, but essentially I am going to have to have one made. I hate the thought of using 2 adaptors to make some other line fit.
I made up a new copper main supply line, and everything is nice and shiny to the L-fitting. I will keep you posted on what will transpire.

here is a picture of the gas line in question

UWE, I replaced the old regulator with a new automatic, and I replaced the line with a rubber one from CW. I used a new fitting at the top. It fit the swivel end of the new line. At the bottom the new line doesn't fit the old LPflair, which is an el flair. So I need a 5/8 flair to a 1/2 reducer. May have to go to pipe and then 1/2 flair. If you want to keep the old reg. you should be able to find a 5/8 double ended flex pipe. Try an appliance store. I also replaced the cylinder lines with the new wrenchless lines.

Just found this old thread...which remained unresolved.
A very kind form member sent me an original and perfect gas line to replace my old one. It was a perfect fit. This is a Rego regulator, btw.
I sold this trailer (1971 Tradewwind) over a year ago, btw. Got me a 1963 Overlander to replace it.

Hello there,
I have run into the same problem and need to replace my accordion metal hose. I can't seem to find even what it's called to replace it. Did you, in you research, find what would fit? Would 5/8 double end work without adapters?
Thanks
