This was perfect. Thank you. I watched because I didn’t know how to identify new/old cans and new/old manifold gauges. This covered it so now I can shop. Thanks.
The self sealing can requirement has made things a PITA. Needed 3 cans to charge my vehicle and had to use 5 with possibly 2 wasted due to the poor quality of the valves. Had both the new style and the old piercing type using a manifold gauge set. All 5 worked poorly due to limited flow from the can. I think the EPA has created an unintended consequence due to poor can/valve manufacturing that will lead to people taking unorthodox methods to extract the refrigerant or the less responsible just throwing defective cans in the trash. I'm glad it's still available to consumers, I think the new regulation will result in more harm than good. Great video by the way !
The Schradeer in the Super Tech brand of cans I just bought (Sep 2023) at Walmart do not seal if I remove the valve. I bought Super Tech R134a sealant and Super Tech R134a to repair my fridge. So far the repair is working and I have 10 degrees F in the freezer compartment. We'll see if the repair lasts or I get to buy a new fridge.
Thanks for the video. I was recharging my van after installing a new AC system and ran into problems. I had old two cans of refrigerant that I've had for years and they went in with no problem, but when I tried to put in the next can that I bought this morning, it wouldn't go in and I couldn't figure out why. I noticed that when I removed the tap the can stopped leaking, so I figured it must be some EPA bravo sierra so I started investigating. Thanks for clearing it up.
Very amazing video bro very straight to the point, so helpful i now know exactly what i need to do the job right appreciate your time to upload this video !
Thanks you saved me a couple bucks, I thought it was mandatory that I had to buy that adapter. But I have the new can, and new style valve. So no need for that adapter.
Got that same A/C Pro hose/gauge as well as an old puncture valve....wondered why neither worked with my new can of 134A. Thanks for the heads up on the black plastic adapter thingy....man, do I feel old. (I am old)
Great little video - thanks! So when you connect the new valve you turn the handle all the way clockwise to release the freon and then leave it there while it's connected to the LOW pressure side of the AC system? I wasn't sure because the old system you pierce the top and then you turn the knob counterclockwise to release the r134a.
i was having trouble getting the new valve r134 to come out, even with the new piercing valve. it was because i put a schraeder adapter on the out port of the new valve, that goes to the gauge's yellow service hose. so i took off the adapter, and i'll try it the next time i recharge.
I had bought the new style valve to use with a self seal can and for some reason the Freon was not charging in to the system, I don’t know if it was the manifold not working , but when I removed the valve from the hose refrigerant started coming out and couldn’t get the valve to close down the can, not sure if i needed the adapter plus the new style valve but ima give a second try with adapter
Have you ever experienced attaching a new style valve to the new style can, but refrigerant doesn’t flow out? I’m having that issue and I bought two different new style valves.
Thanks for the video. I was sitting there thinking what I am doing wrong? Is my valve damaged? Needed to add refrigerant to my mother-laws car. I will go purchase me an adapter and hope that I did not damage the Schrader valve on the can.
@@davidgomez3737 Maybe both. The hole in the can is 3mm, so if the tip is that size it will block the flow. Skinnier ones wobble off the valve if they are still pointed and bugger it.
The video is great but If you showed the two types of taps tips first then it is easier to understand how they work. Basically the piercing type won't work with new cans unless you get the adapter.
my can with the Schrader valve leaked like razy even using the new valve. could I have damaged it by turning it to far in ? it got very cold so could it have frozen ? I tried taking the valve right off thinking it would seal but nope.. whole can rushed out.. did I do something wrong ?
the new can makes sense. Think of spray paint. Its the same valve. If you pull the trigger off spray paint it wont leak. I bought r132a today and borrowed a manifold and the autozone doesnt know the cans seal???
I was literally out there for an hour wondering what the fuck i was doing wrong. I literally worked residential hvac and this truck was kicking my ass. I knew it had to be something fundamental like this..
Great info! Help! My manifold gauge set (Harbor Freight) has a 1/2" yellow service hose, but every self sealing can tap only accommodates 1/4" service hoses. Please enlighten me! Thank you!
@@cuulongquach3482 I physically measure the threads of my yellow service hose and it is 1/2 inch. I took my gauges to O'Reilly to look at their can tap, the clerk opened it up and my hose fit exactly. So I'm not sure why a/c service hoses are so confusing between sizes. But the $7.99 unit at O'Reilly needed no adapter at all.
The old piercing tips may wobble and run off the side of the schrader and ruin it. One that I have has a tip that is so fat it plugged the hole in the top of the can. Of course you can't see what is going on inside there. Maybe you can grind a flat end on the piercing tip.
I have old cans (puncture style) but new self sealing service hoses. Will it pierce the can (I havent tried yet) or is there any adapter for that? I would hate to have to buy old hoses
Best option is to buy new cans. The schraders will eventually leak while the pierce style will not unless it rusts. So save the piercing-style cans for long term and buy and use new cans while the refrigerant is still available. Eventually the price of the old style cans will go up when new is no longer being made.
So... The can tap port were you connect the yellow hose does not have any schrader valve; and the yellow hose does have a pin to push in a valve when screwing on the two connections together. So if the can tap does not have any type of valve, how does the liquid began to flow because the yellow hose is not being pushed in by any thing?
I believe, then that yellow hose was made to attach to a manifold w/ a valve. My manifold has two yellow ports one valved and one w/o. I believe it work as a check valve to keep any refrigerant from flowing into the can if you accidentally hook it to the high side.
I have an old style piercing can tap, and I can't get anything out of the new style schrader valve cans. Different throw and shape of the pushing pin. Sort of annoying that I had to go to the store just to buy another can tap, but what are you gonna do?
Just want to comment that if anyone is thinking of picking up the plastic spin-on adapter for the new Shrader valve cans, it worked for me. I can still use my old low-side gauge (which is good for a quick top-off). I paid three dollars for it at O'Reilly's, but Autozone, Home Depot, etc. have them as well.
@@ohger1 Thanks. I read a few reviews and it seems these are rather fragile being made all plastic. Same for the one in the video. I wonder if there's a metal model.
Well, I tried to empty a super tech can for 1/2 hour or so and barely moved. With my would say 12 years old charger. It throws light at it. I went to Walmart web page to see what the f is wrong with super tech can of r134 and there write "Requires a new EPA Self-Sealing Valve Recharge Hose or Adapter for old style Recharge Hoses." If would not exist internet, and yes, I lived in time before the Internet, I would probably never have figured this out.
The EPA should have made the threads or size of the threads different than the old style can, so it would not fit. That way you cant use the old style adapter and damage the schrader valve.
I can't seems to empty that self sealing r134 there is always at least 2 ounces that won't come out no matter what,that new self sealing is a pain and wasteful.It will. protect the environment but not your wallet.
New style cans SUCK - it takes 5 times as long for the can to discharge and its super fiddly trying to get the depth of the plunger right especially with cheap chinese manufold guage sets

I couldnt get it in today. Thats what she said/ Im gonna heat the dongle up to get it in there
Really informative video.
I read through 80% of the comments and most people are asking questions that were described in the video.
Thanks for the video. I was recharging my van after installing a new AC system and ran into problems.

Dude. Great job on the video. You are super clear and concise. Keep it up.
Well I wasted a huge amount of time trying to figure out why I couldn't get anything out of the can.
Same here
Just what i was looking for. Great explanation and demonstration.
This was the exact video I was looking for thanks bro.
Very amazing video bro very straight to the point, so helpful i now know exactly what i need to do the job right appreciate your time to upload this video !
Exactly what i needed. Thanks man

great 👍 video thank you for sharing my friend 😊
Awesome video!!
You helped me out!
Thank you for the info!
Fantastic video

Very helpful!!
Excellent thank you!!!!
good video thank you , should have shown how the adapter will connect to the old hose used for topping off
Awesome ty!
well explained thank you very much
thanks man

Can you attach the a/c pro gauge old style into the self sealing valve tap? Or it only attach to the plastic adapter?
The adapter shown at 1:10 at Walmart "Interdynamics R-134a Recharge Hose Adapter/Self-Sealing Cans"
I still have 8 cans never used because I never had the adapter,,bought at Walmart, so I understand
did not know that.. thanks!
👍
Have you ever experienced attaching a new style valve to the new style can, but refrigerant doesn’t flow out? I’m having that issue and I bought two different new style valves.

Just grind the side of the old style piercing edge pin so it doesn’t seal against the o ring in the can, works fine.
The side of the pin or the tip of the pin
@@davidgomez3737 Maybe both. The hole in the can is 3mm, so if the tip is that size it will block the flow. Skinnier ones wobble off the valve if they are still pointed and bugger it.
So can i use the piercing hose new on old style cans. I will empty whole can dont need to save
The video is great but If you showed the two types of taps tips first then it is easier to understand how they work. Basically the piercing type won't work with new cans unless you get the adapter.
The new cans are a PITA. I got the proper tap and when I went to depress the valve in the can, the valve broke off and fell into can.
my can with the Schrader valve leaked like razy even using the new valve. could I have damaged it by turning it to far in ? it got very cold so could it have frozen ? I tried taking the valve right off thinking it would seal but nope.. whole can rushed out.. did I do something wrong ?
The EPA fucks everything up
Why? You get to save surplus gas now. There's no pleasing some lol!
What’s the difference between a hose that works on a sealed r134a can and an unsealed?
the new can makes sense. Think of spray paint. Its the same valve. If you pull the trigger off spray paint it wont leak. I bought r132a today and borrowed a manifold and the autozone doesnt know the cans seal???
Thank you
How come my yellow line won't attach to these valves?
I was literally out there for an hour wondering what the fuck i was doing wrong. I literally worked residential hvac and this truck was kicking my ass. I knew it had to be something fundamental like this..
Great info! Help! My manifold gauge set (Harbor Freight) has a 1/2" yellow service hose, but every self sealing can tap only accommodates 1/4" service hoses. Please enlighten me! Thank you!
You'll need an adapter 1/4 to 1/2 . Many self sealing tap comes with this adapter
@@cuulongquach3482 I physically measure the threads of my yellow service hose and it is 1/2 inch.

What if I flatten the piercing style can tap. Will it be working for self-sealing caps?
Easier to simply get the correct tap. But chances are it won't work well either.
I also got caught with this issue. Now I have 3 of the new R134a cans and 1 of the old R134a can for the last 7oz.. Don't much know which way to go..
I have old cans (puncture style) but new self sealing service hoses. Will it pierce the can (I havent tried yet) or is there any adapter for that? I would hate to have to buy old hoses
He said just find an old puncture style service port or adapter.

Thanks
So what size is the port on the new style cans? What service port size should i buy for self sealing cans?
Nope. You'll need an adapter to fit the new tap onto your manifold charge hose. They are different size.
All you got to do is grind the sharp point off.
Part number for adapter
What if you used a piercing style on a the new self sealing refrigerant can?
He explained in the video: Could get some out, but then wouldn't seal again.
I have an old style piercing can tap, and I can't get anything out of the new style schrader valve cans. Different throw and shape of the pushing pin. Sort of annoying that I had to go to the store just to buy another can tap, but what are you gonna do?

Can you point a link with the adapter ? I can't seem to find one on Amazon
@@ohger1 Thanks. I read a few reviews and it seems these are rather fragile being made all plastic. Same for the one in the video. I wonder if there's a metal model.
@@Peppermint1 I haven't seen a metal one, but this seems very well made. For three bucks I'll buy another if I break it.

Old and new style cans and taps are not clearly marked. Autozone and HF salespeople don't know the difference.
i was out there for another hour refilling it. in the same situation fuck those epa guys.
I COULD NEVER GET THE NEW STYLE TO WORK! IT NEVER SEALS BACK UP! JUNK!
New style cans SUCK - it takes 5 times as long for the can to discharge and its super fiddly trying to get the depth of the plunger right especially with cheap chinese manufold guage sets
Your writing on the wall spoils ones view.
Self seal sucks
