Hoses

I am having trouble finding the copper hose connecting the regulator to the main gas line. The old fittings are 5/8 course threads. 1 Is it okay to use the black rubber like hose? 2 Should I replace the regulator? I believe the RV has the original regulator.

Same here! I did find the correct 5/8 to 1/2 FLARE adapter in Austin that fit out Excella.

Here is a source on the internet:

Here is another link on McMaster-Carr for lots of LP pipe fittings. This includes hose fittings you requested..
McMaster-Carr

Here is a link to their premade LP gas lines:
McMaster-Carr

Here is a link to new 'auto changeover' regulator if you have 'dual' LP bottles:
Auto Changeover LP Gas Regulator 66-8922 [59005] - $44.95 : Out-of-Doors Mart!, More Airstream Parts on-line than anyone!

If you only have a single bottle of LP or want other choices, this is an Amazon search..:
Amazon.com: propane hose with regulator

Thank you cwf. So you are using the black hose? I am planning a trip to the Austin area. Any information of where you found your fittings would be appreciated. Also, are there any RV salvage yards in the area?

Mia D. Howdy!

Look up Crump here
http://www.crumpplumbingsupply.com/. They had parts. Bring old and new parts since traveling so far.

I got new hoses from local RV store as recommended by Airstream. Once you know what works you can replace wherever you are on the road.

Also replaced regulator from RV store. All required adjustments to original design. Part of life at times.

Peace and blessings.
Channing

Channing thank you very much for this valuable information. I have been all over looking for parts. You are so right about making adjustments. With making life adjustments, I am learning why should my life of restoring my Argosy be any different.
Happy Camping,
Mia

In general, RVs use type K copper tubing, flare fittings, and forged flare nuts. That is what mine has, although I think there might be a few places where joints were silver soldered instead.

You probably have 3/8" outside diameter tubing. The threaded fittings are somewhat larger than the tubing itself, and are sold by tubing size.

You can buy copper tubing, and inexpensive tools to flare it, at home centers.

Advice varies on whether to replace regulators due to age. I replaced mine.

Jammer thank you. I have the flare tool, it was used to flare the copper during the installation of the line on the RV. Is it not a good idea to have a stiff connection? There was a copper flexible hose connecting the regulator to the main line with a brass ell.

I've never seen a copper flexible hose. Perhaps the outer rubber covering has deteriorated and fallen off from sun exposure, leaving a slightly rusted steel braid that looks somewhat like copper.

In general, propane itself causes hoses to deteriorate, so they have a limited service life. My trailer does have a hose from the regulator down to the copper line that extends back from the tanks. I think a hose, rather than hard line, was used more as an installation convenience than for any other reason.

I like your setup cwf. One hose to the main line, the other two to the bottles. Looks a lot safer than what I have. Thank you posting a picture. Is your hose UIL rated? Not sure I have the the correct letters in the rating

Yes, lines are specific for LP fuel. All hose connections are mechanically crimped to fittings.
If you go to any RV store they should have these. They will flow sufficient volume to feed any use in your AS. If you want also to feed other things like external LP heaters or BBQ pit youse not have enough "supply". Each LP bottle can roughly put out 32,000 btu before it starts freezing up. If weather is cold enough for jacket the output starts dropping off but still sufficient for RV needs.

Super cool!! I don't have to worry about the copper anymore!! I like the idea of of flexible hoses. In my mind it makes less apt to leak, than a stiff connection.
