Enviro-Safe 3226 Can Tap with Gauge - R-134a can to R-12/R-22 port

Worked great didn’t even need to get the adapter! The plastic around the meter is feels cheap but for the price it’s definitely worth it

Worked perfectly. After using a piercing line tap… I used this to add 134A freon to my side by side Frigidaire fridge freezer. The fridge is working perfectly now. Well worth the money.

I'm a big time DIY guy. I'm also a stubborn SOB when it comes to attempting to fix something. And I'm not afraid to tackle something just a little out of the realm of my purview ...especially if I'm faced with a "I've got nothing to lose by trying" scenario.Such was the case with our 7 year old Samsung refrigerator. Long story short, the fridge died a quick slow death; over the period of 3 days it came to a point it couldn't produce cold and freezing temperatures. All indications pointed to a loss of refrigerant ...a leak. I read more than a few "pro" HVAC/Refrigeration forums indicating the condition of my fridge was terminal. I also read a few forum postings indicating a recharged fridge might just last quite awhile ...to the tune of 10 years and counting in one case. A new fridge for us was gonna be in the 1700 - 2000 buckaroos range. Scenario: I had nothing to lose by trying.To recharge your fridge you need this hose and gauge setup and your fridge must use R134a as the refrigerant. The quality of the gauge setup is quite good. There are no instructions included with the adapter but it is fairly straight forward. The only downside to this setup is once you connect the can of R134a to the can adapter and piercing valve, it's on there for good. If you unscrew the can you'll lose all the 134a. There is no way to remove the can piercing valve from the rest of the adapter ...ergo my knocking it a star. Also, you will need to "zero" the gauge before you begin the refill process. Unscrew the plastic lens from the gauge and using a small screwdriver turn the zero set screw on the dial face until the needle points at zero. This gauge setup works with R134a refrigerant ...this is the same stuff used in automotive AC systems meaning it's cheap and easy to get. UPDATE: newest cans of R134a are now made with resealable valves ...which means you need to buy an adapter if you're using a resealable can with a piercing valve setup ...which is what this gauge setup uses. You can usually find these adapters at your auto parts store at the AC servicing display. If your fridge uses the old R22 refrigerant ...it *is* time for a new fridge.With this hose and gauge setup you'll need a small can of R134a. You will also need this: Supco BPV31D Bullet Piercing Valve. The piercing valve is available here on Amazon ...just copy and paste to the search window. You will also need to review a YouTube vid showing you how relatively easy this process is. Fire up the YouTube app and type in: "Vegas RoManiac" "how to add freon to your refrigerator 134a". I am in no way in cahoots with this guy on the video. You can find a lot of vids on doing this job ...I know, I waded through a bunch of them ...and most are *really* bad. Mr RoManiac is the best, clearest and on point vid plus he provides all the Amazon links for the stuff you need to try this. While you're Amazon ordering you might toss in a couple of thermometers so you can assess the health of your refrigerator: Valterra Silver A10-2620VP Fridge/Freezer Thermometer. Depending on the severity of the leak, you might have to recharge the fridge again sometime in the future ..maybe sooner than later ...which you will be able to pick up on by how the fridge maintains its temperatures.So how did I do? Very successfully. It's been going on two weeks now since I did the recharge and so far so good. Every day I don't have to buy a new fridge is money in the bank. All told, it cost me less than 30 bucks to resurrect my dead Samsung. Buying this adapter is definitely cheaper than buying a new fridge.

I bought a can of R-134a refrigerant that had a hose and gauge - but this one was more precise, and the quality was much better. Used with the piercing valve and was able to recharge my refrigerator myself, saving hundreds of dollars!

Found a YouTube video showing how to recharge a refrigerator. In the video, this was being used, with a link. Searched Amazon and located it. Don’t listen to no sayers which tell you that you must call a technician. If you purchase this, along with the piercing apparatus, and get a can of Freon, you can recharge your refrigerator without depleting your money at a lot less than purchasing a used or new refrigerator.

I bought this to recharge a refrigerator that was not keeping the freezer section cold (verified no frost in freezer compartment and no freezer sensor issue). I paired it with a can of pure 134a refigerant that had a self-sealing valve on it. The new self-sealing cans ARE designed to be backward compatible with piercing taps, so it SHOULD work out of the box. However, the problem is the green washer used in the can fitting is way too thick. Way way too thick (if youre reading this, Enviro-safe, please consider changing the green washer part you use out for something thinner). First, I got the blue adapter that's so popular, which didn't work because it was still TOO THICK. So in desperate need of a cold freezer, I decided to modify the product to make it work.To other customers who run into this problem: In order to have it work with a new self sealing can, all I had to do was remove the green rubber washer from the tap, cut it in half height-wise (which sounds hard, but squeeze it with a pair of pliers, cut gently through it one side at a time and peel the bits away as you go. took about 5 mins to do with a dull knife). After doing that and putting back in the now thinner washer (still plenty thick to seal the can), the tap worked perfectly without needing any other adapter.I am going with three stars, which part of me feels like is still pretty generous. It works just fine as a piercing can adapter, if they still sold piercing cans. Like I said, the new cans should work with these old style taps, if the taps have enough travel from out to in. When too thick of a washer is used, they don't. In the USA, all cans are sold now with self sealing valves which is a much better can design, since theres no wasted product if you only need a partial can, AND the valve opens slower making recharge work safer/easier. The maker of this product really should be aware that they created a design flaw and correct it, which would be very easy for them to do.

Received my gauge today. Connected the can tap to a can of walmart brand supertech r134a, then connected the other end to a factory installed service port valve coming off the compressor. Turned on the freezer and the gauge went down to near -18 inHG (in the green zone). Ran the can tap down into the can of r134a and backed it out and...NOTHING! No refrigerate came out! Had to run the tap in and out about 5 times until finally the refrigerate started entering the system. From there I just followed the YOUtube video method of letting the system sip the refrigerate very slowly until I had about 4 lbs of pressure on the gauge. That was at 10 am. By 3 pm today the freezer is below 0 F! All things considered, I found the gauge to be of good quality. The hoses are crimped well and the fittings seem to work just fine. Note: I think the can tap is having a hard time because some cans of r134a are now "self sealing" and it is hard for the tap to make an adequate puncture (maybe?). Anyway, very happy with my purchase. Fixed my freezer for about $20!
