My nuts are frozen

[Chasemmc]

And it's not even January. 3/8" original flare nut on copper water line frozen to 3 way "T" and to the copper pipe. Any way to free this up or am I better off cutting it out and rebuilding? Hit with pb blaster - no joy. Any issue using compression fitting instead of flare if replaced?Mark

heat it if you can if not cut and re flare.

I dont even own compression fittings.

Flare is far better

Call a doctor you have something really wrong. 😂

Hot cocoa and a hot water bottle might help?

Try sharkbyte fittings. easy to use, forgiving and pretty much bullet proof.

If they are frozen to the porch spray Pam on them next time. Otherwise I would solder new copper with silver solder. It will be there til the cows come home

Does shark bite have a translation from 3/8 copper refer line to their system?Can you U solder a rigid fitting to the 3/8" refer copper water line?

[Briankinley2004]

You should be able to solder refrigeration tubing to pipe. There are also adapters available to solder on as well. You can also take a swedging tool and open one end of the 3/8" tubing and go tubing to tubing if you stay with copper. Remember where you go to find the fittings will determine size. Refrigeration guys use the OD of the tubing while plumbers use ID. So a 3/4" water pipe may be crossed with 7/8" hvac if memory serves me right. Sharkbyte offers pipe to thread so you could connect two sizes with threaded if you go this route. I have seen the gaskets in shark bytes give problems over time but may be poor install

They worked fine woth the copper lines hattera used

When I heat the existing flare nut, do u let it cool before trying to free up (using expansion only to break corrosion bond) or do you apply torque while hot?
