Supco has the same part numbers, just SF instead of CD.
I agree, this is probably one of the best low loss fittings. Yes nothing new but, a lot of guys don't know about them. I hear the Accutools are also very good.
Jon HVAC the set I got from them seemed to engage the shrader before being fully seated. Maybe I’m just tightening it down too far, but it concerned me, I can’t have that when trying to use it in an evacuation.
@@tcphvacr9950 Well that ain't no good.
I think I'm just going to use these EVERY TIME i put my gages on regardless of using hoses or the stubbies
can these effect pressures at all? I had two tune ups on ac's that had the exact same sh/sc and pressures....
The only issue with pressure you would have is if it doesn’t depress the core. If your pressures were proper for the unit (eg. If you had 110/280 pressures on a 410A system), the reason they were the same was the fact the conditions were very similar on each job.
@@tcphvacr9950 for 3 units i serviced, they were just under 100/200..
Hey I just picked up some depressors. I’m noticing the thumb screw is very stiff. Not quite one handed operation yet. In your experience do they ease up a bit?
Yes, they get better with use.
Nylog on the stem
@@tcphvacr9950 just loosen the stem nut a little bit to loosen up. I had one that was hard to turn right out of the box and that's what I did. Works great now.
Absolutely. Too bad the male flare isn't at an angle so the swivel ball valve isn't necessary.
I hope you have a dedicated manifold for doing most of your work on, maybe it's just my preference but I don't like the idea of having to be a plumber to check pressures and add refrigerant. 2 depressors, a ball valve, and a tee?
Good video though I'll definitely take a look at getting some depressors
Connor Cruz I never use a manifold to check things anymore. I’ll use the depressor and the Appion gauge (45 degree ball valve only if it’s in a spot the gauge won’t fit, which hasn’t happened yet), and it’s really not that difficult. I don’t miss it at all. But that’s my preference. I have no beef with anyone who prefers a manifold set. I posted this because I was seeing someone in particular hooking up their wireless probes to systems with 6 inch extensions, and blowing liquid all over every time they hooked up and disconnected from systems. It seemed pointless to use wireless probes and waste more refrigerant than somebody using a manifold with gas savers.
I just bought one for my gauge for my high side shoulder I have another one for my low side too
I use appions version of this. I havent seen any refrigerant since i got them
I picked up 4 of those recently myself. They are excellent. And they are vacuum rated, and have already used them to evacuate 2 circuits on a roof top unit.
Great tip, I'm subbed up
Had no idea c&d makes the bigger ones. I have the smaller ones and the thumb screw is way too small and sometimes neeed to use pliers
I agree totally, the small thumbscrew is a pain, especially if you get oil on your fingers.
Also are these not for regular 1/4” ports?
Did some reseArch
The 2060s are for 1/4”
i have the same ones, you use pliers? youre gonna f em up bro, tighten up those rookie hands, stay blessed
What about purging air from those parts.
Thanks I do need them and hope to get tem soon
Can I use these to add and remove refrigerant?.
You can, but it will really slow it down. If possible, Appion core removal tools are the better option.
@@tcphvacr9950 awesome, the gas part always makes me nervous so anything that minimizes my contact with that I'm looking for.
Will they hold a deep vacuum ?
If you get the bigger ones that can backseat and keep the gas in a hose, maybe. I’ve used one out of necessity on a unit vent compressor, there was no way to get a core tool on it, and it did okay.
please do some sequence of operation, thanks
C&D Valve CD2070 Large Thumb Screw Core Depressor with Back Seat , I bought the tool but it doesn't work, the refrigerant started spraying out of the thumbscrew. Do you have any tips on the use?
I’d try tightening the packing cap on top, and if it still doesn’t work, I’d return it. When it sprays out on the flare connection that you connect to (the outlet), I have found removing the core depressor on digital gauges stops that. The depressors seem to keep the gasket from seating well.
I also had that same problem with one of my thumb screw core depressor. The ring seals were installed wrong at the factory. I swapped them around and now no more leak's. You install the smaller thin ring first and the larger one last. I compared it with good working one and no more leak's.
Can you rebuild the stem seals?
I don’t think so, they just sell the o-rings where they go on the schrader.
