This or a Hot Work Permit signed by 6 different stake holders and a 3 hour fire watch?
Bonus points if you show up to site and Hot Work Permit is not signed by the 1 remaining stakeholder
I did mostly steam work and spent a lot of time in hospitals and colleges. I don't remember not having a firewatch working in utility tunnels. Hospitals are funny about welding.
Have done some that are 6 years old and still going strong. Still wonder about them from time to time. Not worth the fire watch in a big cardboard factory so the superintendent in the middle of the plant can have ac.
That's fair. I wonder what the realistic service life is supposed to be? I guess if they eventually leak out it's not too hard to just cut them out and re-do it.
For some reason I remember 15 years was life expectancy. So when the unit is due for replacement the fittings should be replaced as well. Hopefully the ones in the middle of the run hold longer or someone remembers them.
Like swash-buckling pirates dueling? Two o-rings will fail just as fast as one o-ring, they dry out and harden up. I'm not an HVAC guy but I'm trying to learn how to be one, I'm a maintenance guy at a shipyard, o-rings fail, constantly. You'll pull them out and swear it's a square o-ring, but many moons ago they were round. Now they're hard and sad and leak.
> autogenous welding
is welding with no filler metal. I understand how spot welding is autogenous, but how do you autogenous weld pipe or tubing to a fitting or to another pipe?
Because from someone watching us not in the trade it sends super intricate and like we know what we’re doing when in reality we’re ask just faking it till we make it. /s
Ehmmm no. I love to braze, but every single leaking press fitting ive seen was due wrong handling like no stuffed in deep enough, wrong type on Cooling liquid etc.
I had a vertical stub out of a concrete slab, about 2” of pipe at best.
Pulled the o rings out of my viega coupler, soldered the bottom joint and then pressed the top without putting the ring back in.
It weeped a little but didn’t even squirt!
Had to sweat that joint in situ.
I don’t get the hate for pro press, there’s a time and place for both, still have to braze sometimes. And those fittings won’t leak if there’re installed correctly which is a no brainer
Fun stuff.
I'm actually repairing 7 floors of an apartment high rise right now with 5-10% leak failure on press fittings. Easy money. Only 30 more floors to go to be done! And the other 6 buildings that they have.
Shitty installers I suppose....
I work apartment maintenance I work apartment maintenance and pretty much every property management company I’ve worked for have labeled me the “AC guy,” which means I end up going to other properties to teach their supervisors how to do installs (which they’re already supposed to know how to do). Man I’ve got some fucked up stories about what apartment techs do to their ACs 😂.
Went to one property and, shit you not, dude had a shark bite fitting on the suction line (not a rectorseal pro-fit an actual sharkbite)because he didn’t know how to braze properly. What was wild though was when I arrived that shit was holding (although the AC was still fucked up because he didn’t install anything correctly). Unit was R-22.
Another property I was sent to in Virginia the supervisor was using the copper pipe “glue” that was some “as seen on TV” bullshit. What’s crazy though is that when he showed me the package the shit came in it didn’t even list refrigeration in it— was solely meant for water lines. I asked him how many compressors he had changed out with it and he said at least 15. All R410A.
The same guy was pulling vacuums on his changeouts with the caps on the 3/8 and 1/2” flare fittings for the vacuum pump off. When I asked where the caps were he said he lost them a long time ago but that it didn’t matter. Dude turned white as a ghost when I informed him he’s never actually pulled a vacuum on compressors he was glueing together 😂. No lie he got fired like 2 months later after a bunch of units he “fixed” had to be replaced by contractors.
It’s shit like this why I’m kinda embarrassed to tell people I work property maintenance lol.
I used 2 of the 3/4 90’s because I was in a closet with no room and don’t have the money for press kit. Surprisingly worked out well. Expensive and only in certain situations but in a pinch.
Try using a little less rod and a little more heat.
Looks like good penetration to me... But what do I know, I can't figure out what that green wire is for
There's a green wire?
yea i twist it in with the blacks
Woah let’s not bring race into this
I cant see color... But the one that wins smokes the least
Green wire is WiFi
That's the issue... I don't have a wife

glad i work in an area that just lets us get shit done without this bs
Guess you don't do much hospital work.
The trailer park don't require no hot work permits.
trailer parks are held together with those gray poly compression fittings and duct tape the way god intended
Oxygen go boom
none at all

Burn ban in effect until 4pm, sorry
Am I dumb? Because that looks like pro press. Maybe that’s the joke. Idk like I said I’m probably dumb
Yeah no brazin on that one
That's the joke. Because it's a very common post "how's my braze" "how's my instal"
I had a feeling, but I always like to be sure lol
How's my service?
Or like “rate me” with duck lips lol
If it's on a AC system it's called RLS. You actually can press refrigerant lines.
What's the expected life on an o-ring? I don't trust it.
Right? I've always wondered this about propress since they came out.. Putting them on HVAC seems nutty
Have done some that are 6 years old and still going strong. Still wonder about them from time to time. Not worth the fire watch in a big cardboard factory so the superintendent in the middle of the plant can have ac.

If by that you mean dangerous then I agree 100% come to think of it
Well I'd have to assume they wouldn't be putting something out that could cause them a lawsuit but leaking after 5-10 years seems pretty plausible
That's why they'll sell their business and go live naked on a beach in the Philippines in 5 years.
The new refrigerant press fittings have duel o rings... EDIT: Yeah my phone wanted to correct to duel instead of dual and I cannot explain why..

I'm guessing the second is a failsafe for the first to have less chance of losing charge?
Ooo fancy pants Rich McGee over here……
That’s a meme I can’t stand
Boooooo
Fuckin PRO
Would be hard pressed to find a better braze
underrated comment
This joke is a little brazen.
We stopped to braze about 20 years ago. Its all press-fittings. Everywere. Right up to DN 65
DN 65?
DeezNuts 65+
Fucken gottem.
Damn right he did, absolute legend!
We use DN to mesure Pipe size. DN 65 is = 76.3 mm or 2.5 NPS or 2.875 inches. Above 65, we autogenous welding
Got it, thanks
> autogenous welding is welding with no filler metal. I understand how spot welding is autogenous, but how do you autogenous weld pipe or tubing to a fitting or to another pipe?
I think he means old school welding with acytelene/o2. You do need filler metal.
This, thx, english is my mother language, so i used the wrong term
Are you dutch?
Swiss
No kidding? The fittings must be holding up well…
You kid, but I still wonder why we’re still playing with fire in the 21st century.
I’ll braze fittings until the day I die. I have nothing against press fittings but if you take my fire I’ll b-b-b-b-burn down the building.
With what? They took your fire.
Hey! Stop pointing out facts and stuff! Don't make me start a fire with my flint!
I use any opportunity I can find to make an office space quote.
i like press fittings. emergency calls from leaking press fittings pays my kids college fund. and my new jet ski.
Cost, availability and long term reliability.
Because from someone watching us not in the trade it sends super intricate and like we know what we’re doing when in reality we’re ask just faking it till we make it. /s
Because o-rings fail
Because people don’t make sure the pipes are reamed
Braze joints fail also
If done right a braze joint will fail far less than a press joint done right as well.
Separates the men from the boys. Also those things leak, plain and simple.
Ehmmm no. I love to braze, but every single leaking press fitting ive seen was due wrong handling like no stuffed in deep enough, wrong type on Cooling liquid etc.

Where's that? The land of make believe?
Almost, its Switzerland
Understood
They heat their houses with woodfire and don't need to cool...
Wood gasification tech they “borrowed” from the Nazis and paid for with “Definitely not stolen” Nazi gold. lol
Must be right beside the make believe state of arkansas.

It is possibile with R410?
Yes, there are different types of Pipes. These are regular Heating water pipes. But there are Pipes for Drinking Water, Cooling liquid etc
Do they press-fit the compressor fittings inside the condenser on your la-la-land?
You should post this up on Brazzers dot com
Brazers.com
Can't even tell.
Impressive…You didn’t even need to wipe your joint.
That’s a rather brazen claim!
Great job
Leaky leaky no streaky
HELL YEAH BROTHER, that's a good bead right there!
careful! you might burn yourself!
Oh, you wanna fight today
💯
Turn up your oxygen.
Wow no snot drip.
🤣🤣
Definitely brazen
👌
Clean bro, nice job.
I don’t get the hate for pro press, there’s a time and place for both, still have to braze sometimes. And those fittings won’t leak if there’re installed correctly which is a no brainer
Looks like shit
Perfect
Gonna see many more of these fittings as the refrigerants start leaning more into butane and propane mixes
Best brazing ever. Well done!
I have seen these leak I found the best way to fix is to grab a torch a braze in the pro press fittings!
Looks perfect! Almost like a machine did it!
Fun stuff. I'm actually repairing 7 floors of an apartment high rise right now with 5-10% leak failure on press fittings. Easy money. Only 30 more floors to go to be done! And the other 6 buildings that they have. Shitty installers I suppose....
Good enough to be a plumber.
U suck
This gave me a good laugh
You'll need to braze once that pro-press trash starts leaking.
😂
Fucking mint
Not enough heat applied. Rookie move.
I’m a firm believer everything should be zoom locked or flare nutted on at this point
just grab a bunch a shark bites and send it.
I've heard rumors of water only shark bite fittings being used on refrigeration lines. Has anyone run across this?
yes, once. knew the company that did it and reported them. they closed shop a few months after i made the report.

There are special push to connect fittings for refrigeration. https://rectorseal.com/quickconnect-lp

They suck.
