LP hoses

Where do I get the 2 hoses that go from the LP tanks? They are a couple of feet long but seem to short, as at the very bottom it's bent so badly that sometimes that my hot water heater and furnace cut off. Especially one of the tanks.

I only wonder if these came with the unit or where installed by PO.

Ipso, I presume you are referring to the flexible rubber pipes from the LP tanks to the regulator. These should be replaced every few years as they harden and start to show signs of cracking. They are usually fitted with a label which shows the year of manufacture. Other good reasons to change yours are that the design changed a couple of years ago, so that the connection to the bottles, (when the bottles are fitted with OPD - Overfill Protection Device- valves) is with a right hand threaded large plastic connector. This is tightened by hand, and no wrench is required. The connectors also have safety features, in that a fire will seal the gas flow. The pipes should run uphill to the regulator, so that oils in the tanks will not contaminate the regulator. The pipes are available in various lengths from Airstream dealers, RV supplies stores, hardware stores for barbeque grills, etc. They are not specific to Airstreams.

I had a similar problem - my tanks were empty and I needed to upgrade to the new OPD valves. In order to take advantage of the safety features of the OPD valves, you also need to upgrade your hoses. My hoses are 36 inches long and I was having difficulty finding the new style hoses in longer lengths. I finally found them here:

The prices are reasonable and they ship quickly.

Hope this helps.

My Airstream still has the copper connections with POL fitting between the tank and regulator. They are OPD compliant tanks, but you can still use a brass POL male fitting to connect to an OPD tank. Most propane distributors can make these up for you if you desire. I usually get a year or more out of a set of tanks so having to use a 7/8" wrench to disconnect tanks is not much of a hassle.

Every couple of years? Is there anything that can be used to treat or protect the hoses to prolong their life? Mine are under cover, so I'm hoping they last longer.

303 Protectant, available from Auto stores and RV stores is excellent.

It depends on where in the country you live, and whether you store your trailer outdoors, or if the front of the coach is shaded when stored outdoors. UV causes the rubber hoses to deteriorate, just like the rubber in your tires. I personally see no need to replace them on a set timetable, but I do replace them at the first sign of cracking.

When in doubt replace your hoses

I had noticed a propane smell near the front of our AS. I completed the 'bubble-test' to see if I could find a noticeable leak and found none. By the way, this test is done by mixing dish soap with water in a spray bottle. You than spray this on the area you suspect is leaking and watch for bubbles to develop. Of course the soapy water will bubble a little bit, but if you have a leak you will find it this way.

Anyway...no leak was found, so I replaced the hoses connecting each tank to the regulator. I also upgraded to the outside threads which allows us to remove the tank by hand instead of using a wrench. The cost of the two hoses was $42 for both from a local RV shop.

The great news is there is no gas smell and as the guy at the store mentioned, these hoses are pure rubber. There is not an internal casing, so once the rubber gets old, the propane will leak through the hose. Hope this helps!

Mitch

Another thing you will want to watch and check for is Rodent damage to the hoses, I have actually had a hose punctured by a squirrel knawing on it. It happen twice to the same hose! So I got a piece of heavy vinyl tubing to slip over the LP hose to protect it. I have also seen stainless steel braided hoses...they would look mighty sharp on an Airstream, but I suspect would have to be custom made....

Now that's a squirrel I'd stay away from with matches

High pressure vs Low pressure hoses.
Anything that is down stream of the regulator would be low pressure?
For instance the main hose coming from the regulator going into the trailer is low pressure right???

Correct. The line(s) from the tank(s) to the regulator are high pressure. Everything else is low pressure.

No gas to heater / refrig

The hoses on our 1976 Caravanner have been upgraded and the tanks just filled. The heater came on for about three hours and then quit and I cannot light the refrigerator. Do you think this has something to do with the new hoses?
