Propane Tank Fitting Breaking

There are two things that might help.. First, the regulator may need support (Assuming that is what is on the other end of that line)

but to replace it with a hose you need a propane professional. Not a "Pump jockey" refill technician but a real propane professional..

how to find one:

Google "propane" followed by your zip code. Like the Propane 12345

Now scan the responses and look for a company with DELIVERY TRUCKS in their logo.. Start calling them.. Odds are one of 'em will have what you need. Likely on a rack on or by the wall.

Option 2 if in Quartsite AX.. Pit Stop has 'em.

Thanks for all the comments.
I replaced the flared union and put a solid support so that it cannot vibrate.
I will let you know if that works.

There is different copper tubing. You use Refrigerant copper tubing. Also, you MUST make sure you create the flare correctly. Too shallow and it will pull loose. Doug

Go to a propane company, and have it fixed properly, very dangerous.

also check to see if someone installed a short flare nut, instead of a long flare nut....this can make a difference in vibration resistance

How about putting some support on the copper line, so it don't vibrate and break.

It's a flare-by-flare union that is found in every hardware store. Not sure if the copper tubing in these unions are soft or rigid. How can I buy one that is soft tubing?

Isn't all copper tubing "soft" that is used in flared fittings? How would it flare without splitting or form a seal if it was "rigid"?

Almost sounds like someone used rigid copper instead of soft copper. Just a crazy guess.
