Greg , first
Welcome to SFT
Second , I have never personally used shark bite connectors , so I have no real world experience to draw on .
Sweating pipe can be done with a propane torch and a minor investment in tools . The tools being a Imp (close quarters) cutter , a cutter that goes to 1-1/8" , a roll of plumbers cloth ( sand paper ) and a few fittings to practice with .
I prefer sweating copper because I am a plumber/pipefitter in building trades .

I had wondered if Sharkbites would work for air lines.
I can just barely scrape up enough courage to use them on exposed water lines but I've got a few that have been in place for a couple of years now.
I've only seen one leak so far; it was installed on a really cruddy 1/2" copper line that had a little dimple in it and even that was a slow leak. All I had to do there was trim about 1/2" off to remove the dimple.
But there's a lot of difference (in my imagination ) between a 30-40 psi water line & a 150 psi air line.
So I dunno.

I have a total of 6 SharkBites above my ceiling in my FLA place.
Each end of 3 patches.
(Copper pipes don’t like RO water.)
Local plumbing house said not to worry.
He sells a lot of them and they don’t come back.

But that is water, not air.

I know, I know ... mine says the same thing.
But their reassurances don't pay the freight if the ship hits the sand.
I think the thing about Sharkbites that makes me nervous is they're just too stinking easy to use. It's the equivalent of a framing nail you could drive with your index finger, or welding half inch plate with a propane torch.
They give the appearance of defying natural law.

I have installed a few shark bite connectors, 1/2" in our server room for the drain on the humidifier (been there 2 yrs w/ no issues) because i was leery of using a torch around all those high dollar puters. and the other was some 1" pex to run soft water to out marley cooling tower. I had to go over and around about 30-40 different sized piped and the pex was the only way to go. Sharkbite connectors are the same thing as push-lok or legirs poly tube fittings that have been in use for a long time. I work in the printing industry where compressed air is our bread and butter, and all of the poly air lines are connected to solenoid valves, cylinders, etc with push-loks (aka sharkbytes). If it weren't for push-loks life would suck. The typical failures I see are fittings installed in harsh enviroments - where heat, chemicals, or oils do the damage. Not the fitting itself failing.

For those of you who watch This Old House, you know the plummer, Rich Trethewy. I've seen him use the shark bite fittings and it's the same story, great for areas that are too risky for a torch.

Has anyone had experience with the crimp-type copper fittings that he's demonstrated on other episodes? The fittings must be a lot cheaper than shark bites but, they probably, make up for it with the special crimper that you need to buy.

Again, something that would be great, in risky to solder areas.
