As others have said, the pipe has been frozen and expanded to the point that no conventional fittings will fit the stretched pipe.

Other than a total re plumb job, you can go back to the closest soldered original fitting and unsolder the pipe from the fitting. The fitting will not have expanded. Then you can solder a short stub of new copper into the fitting, and from there use either Sharkbite type fittings and PEX pipe, or conventional crimp fittings and PEX pipe.

There is no other reasonable way to repair it.

A flaring block will squish the tube back down to size.

Splits are easy to fix with a soldering iron. Just squeeze the tube back together sand, flux and solder.

Shark bite are easy but very expensive.

If you could have a superpower, what would it be?

It's called: Nylon Braided Hose (to size), two hose clamps on either end (real tight), leak fixed ;-)

I have trailers that were fixed that way over 10 years ago and still no leaks!

I was able to change out the copper for Pex in a 75 rear bath in about a day. I disassembled the top of the tub enclosure, the passenger side bed, and the bottom of the kitchen cabinet to get access. It wasn't too bad.
The fact that I am opinionated does not presuppose that I am wrong......

I'm in the same boat as casbc. We loaned out our '68 Airstream and the party we loaned it to didn't winterize it. Multiple ruptures, and with the stretched pipe I've been to every piping and tubing supply store I can find and none could come up with anything that would match the stretched diameters of the different pipe ruptures. I mic'd (micrometer) the diameters of the tubing, and it was stretched to some degree (and to all different degrees) everywhere I measured. I wanted to go the pex route, but without any matching diameters was pulling out both of my hairs too.

I will investigate the swagging tool referenced by gr.austin.

An Airstream dealer in Boise, ID did the initial repairs but did a crummy job with clear plastic tubing that ruptured almost right away. I checked with my local Airstream repair dealer and they confirmed that the copper tubing expands even in areas that didn't fail when the pipes freeze up.

Also to rideair, the patch where the Airstream dealer had diameters that allowed the use of nylon braided hose, the hose did hold up, but where they couldn't get a close enough diameter match they used clear plastic tubing and that failed almost right away.

You can probably replace it all with 1/2" PEX for less trouble than trying to patch it.

If you don't file the copper to the exact diameter of new tubing, a Shark bite connection won't fit. For that reason, I used compression fittings that have a ring that allows you to get the size. Cut your leak out and go back to smallest circumference that you have. Check size with ring and file or emery cloth to allow it to slip on.

Glad to see your Nylon Braided Hose has held up well. There's a reason why it's used in so many industries. Just take a look at the specs!

Silicone Braided Hose FDA and NSF 51 Grade On Harrison Hose & Tubing, Inc.

I know many folks just think it's a white trash, redneck way to fix a leak or such, but if one does their research, they would never use anything else. You might want to take a look, I'm sure these folks have the size you'll need.

Just to add my 2 cents. When i purchased my AS the water system was a hodge lodge of original copper, nylon patches, and even clear tubing patches held together with hose clamps. Every spring more of th original copper would spring a leak till I eventually stopped trying to patch and i ripped it all out except for where it comes in from the street and replaced it with pex. I used the propex system after talking to my friend who is a plumber. He let m borrow his expansion tool and in 4 hours I replumbed the entire AS. Heres a video of how the propex system works. I have no affiliation with this company fyi just a fan after using the product.
