A walkthrough for RLS press fittings in HVACR
Вставка
- Опубліковано 14 лип 2024
- A short video of a step by step process for using press fittings in various HVACR applications. Although, we're only installing a 3/8" bi-flow filter drier here...the same steps apply for any fitting being used.
The minute he dropped that filter dryer on the ground and not cleaning it prior to attaching it to the unit😂
😂 3 years later and the system still doesn’t care
Sometimes change is hard come by. I've used water and a/c press fittings and have not had a leak . Keep up the good work.
That was such a good explanation of the process that you could do the demonstrations for RLS 👌
Just came across your video, thanks for sharing your experience! Great demonstration! We go by RLS now after our partnership with parker ended.
Noted. Thanks for stopping by!
Nice job.
Thanks for sharing
Thank you!! Helpful review. Appreciate it
Very good video! Thank you!
I dont know why people have issues with leaks. We use them on the heads of mini split installs. One less flare!! Love RLS. Havent used them on dryers. Good idea. I did have an issue last week when I put the fitting on it pulled the gasket out. Since then, I put a little nylog on the pipe and that helps slide the fitting over without pulling gasket out.
I’m ready for these residential manufacturers to make the equipment a bit more “press fitting” friendly. It’s hit and miss whether there’s enough straight copper coming out of new fan coils and condensers to use zoomlock/rls.
These RLS fittings have been used for aerospace for several years. I noticed that the fitting hit the dirt after you crimped the first time. I carry small pieces of cardboard to prevent that. Also you realize that Parker has changed to new design fittings and jaws and also they crimp on the larger lip of the new fittings.
@@AIRMANHVAC You'd think the manufacturers would jump all over it seeing how it's better for the equipment to zoomlock rather than heat and risk of contamination if brazing nitrogen is not used. Have you tried the hand crimper? I think supplyhouse online has them for 168.00

Way of the future 💯!!!
That's great. I saw a test and this can hold up to 4000 psi... copper is seal plus the o ring. I think it can hold for many years ..
How about the oil in side line and as u deber the jnside the flakes get in pipe and very hard to make sure u get them all out, so when u put that on it makes a higher risk of missing a flake
1:47 - I hope you didn't ask to borrow that man's phone after knowing what he just did in the background of your video! I used the RLS (Rapid Locking System) tools and fittings for the first time yesterday on a walk-in cooler and had leaks on every fitting. Note to self: the center of the jaws _do not_ go over the rib where the o-ring is in the fitting! I needed to _Read the Fabulous Manual_ before starting.
What type of filter dryer do you use with those ends on it?
The filter Dryer should always be installed inside of the house close to the evaporator coil to prevent corrosion from the outside elements.
@@thomasmcdonald5758 never seen a filter drier fail from the “outside elements”. The reason the filter drier’s preferred location is near the evap coil is to offer better protection for the metering device. Installing it outside near the condenser is a completely acceptable practice. We’ll just have to disagree on that issue.
@@AIRMANHVAC The filter dryer’s manufactured 15-20 year ago had thicker metal and like everything else was made much better, the newer filter dryers have much thinner metal and when they are under snow ice and freezing temperatures the elements cause much faster deterioration.
What brand is that filter drier ?
if next time you need to change dryer again, what can you do? your pipe would be short after you cut the press fittings
Coupling and a piece of copper
In tight situations and where there not much stub remaining, I have had issues removing the couplings
Yea, there’s definitely some cons to using it.
I should use RLS or acr?
What do you do when connecting to a evap coil/service valve/compressor that comes with a swedged end on it?
Hey Mark, cut the bell end off if there’s enough length of straight copper to use a fitting.
@@AIRMANHVACif you can’t cut the service valve could you go up 1 size? If the compressor service valve is 3/4” could I use a 7/8” coupling press fitting?
@@AJDBroski If you have the recommended length of tubing to press the fitting onto, yes.
Hello can you press txv valves?
What brand 3/8 jaw is that I can’t seem to find a Milwaukee that makes that siz e
Size
RLS
How do those o-rings hold up in a place like michigan where temperatures can be 0 to - 15°f in the winter?
HVAC know it all has a ton of videos and test info on RLS fittings. I haven’t had any issues with the fittings we’ve installed around southeast Alabama.
@@AIRMANHVAC happy to hear that, im just concerned about the sub negative temperatures here in michigan. I guess ill have to do some research before I spend a few k's on this tool and fittings.
@@crinklyten2152 biggest downside right now is the equipment manufacturers are not making it simple/easy to use RLS on equipment installs. There’s barely enough straight copper for “hookup” after removing the swaged ends.
@@AIRMANHVAC that is 100% true, Payne has taken a small step towards that, they are leaving the 3/8 straight but the suction line is still swedged.
I get the jobs where you are working in a tight space where you can’t get a torch or like in a place where you need burn permits or fire watch but outside at a condenser is useless I could have had that brazed in half the time it took you to press it
Just showing peeps how to use it here Daniel but thanks for your comment.
That drier connection is pipe dia. Not connector dia. ???
Correct
On a new installation this won’t work on the copper that goes into the valve correct?
If there’s enough straight copper tubing of the correct size for the fitting you’re using, it can be used anywhere.
@@AIRMANHVAC Well there is no RLS fitting that you can use at the valve. So you would have to press the valve directly to the copper with no fitting? Or braze a piece of copper to the valve then use fittings for the rest ?
If there’s enough copper…you cut the bell end off and use an RLS coupling. If there’s not enough copper then I would braze in a piece of straight copper to attach the RLS to or do not use RLS at all for that connection.
The joint is leak ,,, leak but should be changed again, right?
But what about vibrations, heat/cold cycles, longevity before it starts to leak?
Our company has been using zoomlock for 4 years with 0 leaks.
StayBrite#8 and forget about it.
4 years lol, get back to me in about 15 years.
Ditto. Copper is very soft. I don't see how the Seals can be depressed enough and stay stable and or pliable ? Oh well. I'm retired. LOL.
@@hmdwn just ask Europe (50+ years)
Can I use that with my rigid pro press?
I believe there’s a jaw/clamp setup for use with rigid
I have a ridgid rp241 and it says it works with the rj claws
Name of the pressmachine ?
Fixit, it used to be referred to as zoomlock. I believe RLS is what most are calling it now. www.rapidlockingsystem.com/
@@AIRMANHVAC Thanks man!

Zoom lock is for areas at risk for burns,not as a everyday tool🔥
Design a fitting that will attach to the flare at the service vales you lazy but greedy tech guys. If you cant solder just say so.
Yea, we don’t “solder” here with HVAC. We braze. Plenty of videos about that on this channel. This is a video showing how to use this product. Thanks for your ignorant comment though.
@@AIRMANHVAC LOL what ever yank!

Like I Said if you can't weld just say so.
Ken you are either a mouth breather that can’t troubleshoot shit or a lifelong installer. Either way, my guess is your IQ matches the low side psi of a 407c system..
Deburr/ream the pipe but don't clean the pipe! You want that O-ring to seal against a flat SMOOTH surface
You "scuff" the pipe to allow for better adhesion (more surface area) for solders and SilFos
These scratches tear up the O-rings!!
We’re following the zoomlock’s instructions in this video. They indicate to use emery cloth or sponge to remove any dirt or imperfections before installing a fitting.
@@AIRMANHVAC I I've done machining down to 0.001"
they are wrong
Got2Learn posted a video about this
You want the surface as smooth as possible
From factory extrusion vs hand sanding
Think of it as mountains and valleys vs the plains
@@AIRMANHVAC really not sure how to explain here, I am not a good teacher

maybe that explains it 😅
@@AIRMANHVAC I'll be giving them a call, when I sober up
Brazing would have taken 4 minutes....problem is oils in refrigerant will wear the oring out...nonetheless good video but this is a lazy way to connect lines....I have been doing HVAC for over 20 years...
You think, that materials science engineers might have considered refrigerant oils? or are you the only one smart enough here?
I've been doing it for 43 years. I felt the same way when press fittings for water came out. Now I use them constantly. When you're doing a job that requires a lot of fittings, they pay for themselves in the long run, just in labor savings. (4 minutes to braze and 30 seconds to press. 1000 fittings = 58 hours.) Not to mention the time saved not having to wrap a fitting to protect from heat, purge nitrogen through the lines etc... I will be switching to these on Refrigeration as soon as they become popular and the price of fittings start to drop. You need to quit thinking in the past and keep up with the times if you want to make money. As for the O-rings wearing out, probably not in the life of the building.
@@1959Vento nice, I love open-minded individuals 👍
"The sound of progress, my friend!"
Also if you look at the cutaway of the joint, you'll note that the flow of the fluid (whatever it be, water, refrigerant, etc) barely contacts the O-ring; it mainly flows across copper. The O-ring basically just provides a "last defense" seal. It's engineered very well.
PS another bonus: no annealing the copper!! copper heated to brazing temperatures becomes quite soft, bends quite easily...
Sounds like you need to retire dude
