Low Loss Core Depressors

Something I use everyday, and have never regretted finding this tool!

I think I'm just going to use these EVERY TIME i put my gages on regardless of using hoses or the stubbies

[@JDT738126]

Great tip, I'm subbed up

[@stevencarrillo3615]

Thanks I do need them and hope to get tem soon

[@jonhvac]

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.

[@tcphvacr9950]

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.

[@jonhvac]

@@tcphvacr9950 Well that ain't no good.

[@JahonCross]

I just bought one for my gauge for my high side shoulder I have another one for my low side too

[@thisisyourcaptainspeaking2259]

Absolutely. Too bad the male flare isn't at an angle so the swivel ball valve isn't necessary.

please do some sequence of operation, thanks

[@connorcruz6249]

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?

[@connorcruz6249]

Good video though I'll definitely take a look at getting some depressors

[@tcphvacr9950]

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.

[@christophersykes8063]

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?

[@tcphvacr9950]

Yes, they get better with use.

Nylog on the stem

[@ramonestrada38]

@@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.

[@qsm1334]

I use appions version of this. I havent seen any refrigerant since i got them

[@tcphvacr9950]

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.

[@WswRefrigeration]

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

[@tcphvacr9950]

I agree totally, the small thumbscrew is a pain, especially if you get oil on your fingers.

[@WswRefrigeration]

Also are these not for regular 1/4” ports?

[@WswRefrigeration]

Did some reseArch The 2060s are for 1/4”

[@ethanberdejacortez4845]

i have the same ones, you use pliers? youre gonna f em up bro, tighten up those rookie hands, stay blessed

[@marcusaurelis]

can these effect pressures at all? I had two tune ups on ac's that had the exact same sh/sc and pressures....

[@tcphvacr9950]

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.

[@marcusaurelis]

@@tcphvacr9950 for 3 units i serviced, they were just under 100/200..

[@sbitschy]

Can you rebuild the stem seals?

[@tcphvacr9950]

I don’t think so, they just sell the o-rings where they go on the schrader.

[@luvdogsandhorses]

Will they hold a deep vacuum ?

[@tcphvacr9950]

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.

[@timothyripley4175]

Can I use these to add and remove refrigerant?.

[@tcphvacr9950]

You can, but it will really slow it down. If possible, Appion core removal tools are the better option.

[@timothyripley4175]

@@tcphvacr9950 awesome, the gas part always makes me nervous so anything that minimizes my contact with that I'm looking for.

[@welddoctordoc7990]

What app did you say?

[@tcphvacr9950]

Bitzer Refrigerant Ruler app, gives you all the data on all the refrigerants. You can select favorites, so you don’t have to scroll through a list to get to the ones you use the most.

[@MrINSOMNIA28]

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?

[@tcphvacr9950]

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.

[@ramonestrada38]

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.

[@tommyq374]

@@ramonestrada38 i think i might have the same issue, got 2 and one works fine but ones leaking when i put it on, but its a slim slim nut so i dont have a thin enough spanner etc to unscrew it fs
