We did a retrofit equipment on a walk in cooler that needed some love, we ended up using the ZoomLock Max press fittings instead of brazing.

I've seen a local tech use lokring compress fittings, seems a bit different. I've used Mapress by Geberit myself on waterlines which looks like zoomlock max
Cool ..we use shark bite on drain traps…easy to take apart to clean.. Are you in Orleans ?
Do not like the zoom lock unless needed. The look and possible need to un weld something is why. I would have rather left base valves and brazed into them, just my preference.
Nice work though bud! Looks good for what you were trying to prove about tool
small equipment I'll use a sign truck save a ton. Lot times 150 bucks get em out. Service area Barrhaven??
How trustworthy are the zoom lock fittings? Service area Kanata??
I have not used any of the press fittings, but I was told on the plumbing Pro-Press that the b o-ring was not the main seal….but the main seal is the copper on copper seal formed with the high pressure crimp.
I hope to add it to my bag of tricks because I definitely have had times where it would have made a job much easier.
so possible tip keep a dedicated fitting for the depth checks that way you have a "beater" for rough testing and the only time the new one going on is final fitting before crimping Service area Ottawa??
What’s the difference between this and the rls system? Which is what my company was using for a bit.
Just a heads up, I tortured tested those zoomlock and propress fittings (Just basically all the wrong ways to do it, no pipe prep etc.) and they can take ALOT more than you would figure. The only way i actually managed to tear one of the O-rings was slamming the pipe into the fitting on an angle with no de-burring.
I really appreciate the fact that this guy does the little things like putting a bushing on the other side of the connector or making sure he uses the water tight EMT compression connectors rather than just throwing a regular compression connector on it. It's the little things like this that I feel like that actually separates the average guy from real professionals and I must say this guy a real professional
Exposed EMT? I would not have guessed, that pipe won't last in the elements. Better option would be rigid or epoxy coated emt, possibly rigid pvc or carflex ? Love your channel and love learning about HVAC. Electrician by trade and always try to use pride in my work like you do ! Thank you for providing a good example for other tradesmen ! Also I thought you pipe didn't look bad at all!
I remember hearing about zoom lock. An my boss at that present time didn't want to even try it. Nice to see how smooth a install goes.
why use emt and not tec cable ( rubber coated armour cable)?
I couldn't imagine just having warm weather year round, I'd go on a shooting spree LOL!!! BTW, used the Milwaukee pro press tool today to install a pressure regulating valve for a cooling tower on a 1" feed line, gotta love that thing, done in no time flat!
Love the cinderblock holders! I worked with plumber who had a pro press. I thought it was cool.
great video! but not to knock u down, ur a good mechanic, id left the cond. valves on so u could do a pump down test on compressor, set LP or pump down liquid line and know theres no pressure, king valve front seated will read receiver pressure only.
How did you lower the old evap down and then raise the new one up?
The press tool is expensive but can possibly cheaper and safer for reasons, no fire risk. Good job.
Another great job and video!
How do u figure out your winter charge
Great video, thanks for sharing
Looked like a great install. I would like to try Zoomlok when applicable. good job!
I've always wanted to see you use the zoom lock I really am going to invest in that for my company Are you in Nepean ?
Didn't know press fittings can be used for freon… In EU we use this system for water (stainless fittings), heating (so called carbon steel fittings) or natural gas (stainless or copper fittings) for gas boilers. What's the operating pressure for r22, like 20bar ? Will it hold? I've had leaks with this fittings on much lesser pressure, especially with copper fitings. Really want to know if it's ok to use for freon Service area Orleans??
You lose the thrill of an accidental fire with that tooling. Damn. The excitement is gone.
I've only watched a couple of your videos and I have to say that the air con trade seems to be as diverse as the pump trade. You have a bit of electrical, plumbing and mechanical fitting all mixed together. Of course, you probably don't have to deal with raw sewage like we do lol. Are you in Kanata ?
Whenever we run a line set through a cooler top or wall we always put in a piece of PVC first and put the line set through the PVC, prevents The line set from rubbing through on the sharp metal edge of the cooler
Press tools are awesome, I got my plumber the dewalt, but the fittings are so damn spendy Repairs with water still dripping is great.
so refreshing to see working with brand new stuff for once…its all so shiny! lol
My local United says you can’t zoom lock soft copper….I’m guessing that’s not correct? Or no one else has been told that anyway….
I’m old school. 15% Silfos is what I will always use.
Cool man nice tool you have Are you in Ottawa ?
How did the roof jack magically get around that line set, damn you're good!
ZoomLock Max are a real time saver. They should last a very long time.
Good job. CONGRATS !!!!!
Way back when I started on cars, in the early nineties I believe. They were getting rid of R12 and doing the R134. The number one illegal substance brought into the U.S.A. was drugs/cocaine. The number two illegal substance, at the time, was R12. I remember hoarding some one pounds cans myself.
Never seen seal tight fittings for EMT conduit I, normally use threaded rigid when exposed with prefab 90's just to make it easier… nice work.
I still don’t trust pro press I’m a plumber I like my torch
Why you don't use those old style racks anymore? Too long fridgerant lines? Too hard to service?
What a time to be alive.
Got a question though. Do you have any concerns using the zoom lock fittings with leaks in less than a year or two. Or is that why you have heavy emphasis on not screwing up the O-rings while de-burring
good video! learned a lot. keep up the good work
👍+1
I personally haven't used the zoomlock, but I have used pro press a bunch. I still personally prefer to solder an assembly on the work bench (when possible) and just throw in a coupling to tie it in. Most of my mistakes came from trying to keep a complex assembly from falling apart and then not noticing a fitting slipped off or turned after I already started pressing. That depth gauge is pretty sweet. The one we have is basically a laminated piece of paper. Makes it hard to mark the pipe, so most of the time I just use a fitting that has a stop instead.
Tool would work great in computer rooms.
GREAT WORK
In Fla. you have to have electrician run electric code.I like that tool.
Nice installation Chris!
How much are each fittings ?
Lots of nay sayers here. Has anybody taken the time to look at the Specs for the fittings? From Parker the svc life is 25 years with a 10 yr guarantee from the date of purchase. Working pressure is rated at 700psi, Burst pressure is 2100psi How long is the life span of the systems these are installed on. Will the system Chris installed them on last more than 25 years? Have you ever encountered a braze joint that has failed after it was completed? I guess time will tell if theyre a good product.
