Flare nut wrenches

[icehouse]

how would this make a difference?

do I buy refrigeration flare nut wrenches and plumbing flare nut wrenches or are flare nut wrenches just for refrigeration?

the nuts I use them in are for oil, so 3/8" soft copper type.

educate me.

"Refrigeration" flare nuts are also known as long shoulder flare nuts, better sealing when tightened.

Pardon my ignorance,but I have never used them.I am looking for some to purchase and would like to know what/where to get some at.I would use them on flare nuts sizes 1/4 all the way up to 3/4. I have read where now you have to have metric ones as well. Any advice would be greatly appreciated.

There are regular flare nut wrenches and there are Kwik Tite ratcheting wrenches. Check the following thread. Also a video

I have full flare sets in Metric and SAE, they don't fit snug enough on oil and refrigerant fittings, auto service fittings yes. I keep an adjustable/hammer set for everyday use, for flares a 6", 8" and 10" set. I snug the wrench onto the fitting and rock it back and forth slightly while tightening it. Make sure the wrench is in the right direction before turning.

He's talking about the flare nuts, not wrenches.

I thought refrigeration flare nuts had a short shoulder, compared to plumbing flare nuts. That was to prevent ice build up between the shoulder and the piping and causing the ice to crush the piping when it froze. Am I wrong?

I will admit that I have used adjustables every since I have started in this field,I have buggared up a few fittings but I have not done that in years.I have been going behind the fireplace installers fixing their gas leaks and the adjustables are tuff to get in there.

I have always used adjustables or regular wrenches but what is funny is I was cleaning out the garage this weekend and found a brand new set of craftsman flare wrenches that I bought 10 yrs ago and never used. They are now in my truck and gonna try em out
