On the driver's side of the '73 23' CanyonLands, The air line has been cut a few inches from the bag.
Or more specifically, before the shutoff valve. There is a shrader valve between the shutoff valve and the bag, which is currently the only way for the bag to get air.
I would like to splice it back together and see if the compressor/airtank/dash control system will work well enough to inflate the bag to raise the rear instead of using the shrader valve and an external compressor.
If it works, I want to be able to leave the splice in place for the long term.

If the line is cut and all you need is to connect the two pieces. The way I would do it is go to a hardware store and get a 1/4" brass compression coupling with inserts in it for plastic tubing. Then all you need to do is tighten it up like you were joining two sections of 1/4" copper tubing.

They make air line fittings to splice these lines together. Any truck repair facility should have these fittings, and I would assume your local NAPA would as well.
Just be sure to get the DOT approved fittings as they are also made for other applications, but I can't imagine those would be carried at either of the above places.

Mark,
You should be able to find 1/4" air line coupling at Home Depot, Ace, or
Lowes.
This is a listing from McMaster-Carrcatalog.

Jim,
Whoever answers the phone would spend several of your overhead dollars taking the order for an item that you make pennies on.
I appreciate the offer, but I would rather call to place an order that you can make money on instead of nickel and diming you to bankruptcy.
Completely unrelated, if you have an OEM kitchen clock for a 1973 Sequioa in your boneyard, I would love to have one. A PO removed mine, and I think that is one thing that belongs in these old beauties, no matter what else you do to the interior.

Sir: yes you should use DOT stuff. Just a matter of safety. Any big truck or trailer shop should have the lines and fittings.

OK. thanks for the input that I can use too.
So, I have 150 pound plastic line from home depot, one DOT splice from NAPA (more pricey than the splice from home depot.) , and some line that needs splicing. My local NAPA store is out of almost all air line stuff; no one else near by has DOT stuff. How important is it to use DOT stuff? I can splice existing line with either splice since I have one of each - but at least two leaks.Dare I use non DOT plastic line - I use shutoff valves so a line failure would not be catastrophic.
If I need to use DOT, I will go to Jim as I know it will be right and the cost at NAPA is near ten dollars per splice but they are out of them. Gene will tell me to get on board with the Bovie system and get over all my old lines etc. I may do that but not this week. The old girl had her 40th birthday not too many weeks ago and I think that 40 years may be the mandatory self destruct time for some components like air line.

I don't disagree that DOT is better and realy a necessity for brake lines but it wouldn't worry me to just use a brass coupling for a simple air line. There is probibly less chance of it failing then the line itself.If it did just close the ball valve and air up the bag

Sir: If you get a chance to compare a DOT with a regular fitting you will see 2 main differences. The insert that goes into the hose is made on the fitting and the hole in the compression coller does not have sharp edges. When using a non DOT fitting the insert can be misaligned and when tightening the coller it can get tight enough to score the hose. That simple airline can drop one side of the coach in about 1 second, not a good thing in a curve or any time. I`m just saying that the DOT regulates the manufacture of things like wheels, brakes and suspension parts for a reason. I have delt with these airlines on the big trucks for a long time and they can be damaged and they can be repaired safely. Besides it is illegal to use a non DOT fitting on manuactured vehicles in the US. The installer of a non approved part can be held responsible for any damages or injuries occured.
Of course it is yours and you can do as you wish.. but I wish you wouldn`t..

Prestolok are very good in a clean environment, but not very good in a
fender area.
We always avoid them as most do not understand how to treat that type
fitting.
Jim Bounds and I refuse to sell our kits with the press fit because of that
reason.
Jim B and I have more experiance on coaches.
