• BETTER THAN R134A - ZeroR Refrigerant is lightweight. The net weight is 6oz, but it fills your AC like 16oz of R134a! (See Conversion Chart). Lightweight also means less friction which will make your AC system last longer.
  • UNIVERSAL - ZeroR Refrigerant can be used in most AC systems, although the EPA has regulations stipulating what refrigerant they want you to use in each system. The chemical compound of ZeroR Refrigerant will safely bond with the compounds of R134a, R1234YF, R12, R22 and more!
  • ECO FRIENDLY - R134a is harmful to the environment and is being replaced with R1234YF under EPA regulations. ZeroR AC Refrigerant is even more environmentally friendly than R1234YF!
  • VALUE - Not only is ZeroR Refrigerant less expensive, but on average you use 1 less can per system.
  • SAFE - ZeroR AC Refrigerant is flammable and so is the new EPA approved R1234YF.

The can instructions say to use the can upside down and pump in the liquid form of it into the low pressure valve.... I found that strange because so many other resources suggest to not do it that way. Well it works for now. However for those using The ac pro gauge and hose, it behaved weird , the trigger got stuck, when clogged used to inject the liquid form.

This is a great tool to have. If you have a very small leak that can be mitigated by a can for the summer it will make your life easier. This will not solve a major problem and you still need a tool to connect the can to the suction port. After the scam with Freon prohibition, they did not stop there and now you can not buy R134A, supposedly "safe" alternative in many states without a license. You still need to know what you are doing especially when working with a pressurized can, but you should not have a paper to prove it. Very happy that Amazon (so far) allows you stick your finger in the eye of a stupid bureaucrat.

Glad I I bought the 6 pack. Used them on a couple of automobiles. Can’t beat the price

Used in a 2000 mustang gt. AC is so cold that sometimes when I breathe out I see frost. I'm not kidding, even the AC on 1 will feel like winter in high 70 degree weather. A great advantage to using this stuff is that it is less likely to leak out of your system. Normally when I put R134a i have a very very slow leak and it will be low on freon by week 2 or 3; the compressor would kick on and off every 5 seconds, I might have a small leak at the schrader valve/ low pressure cap It has been since March 6th that I've used this in the mustang and it is now May 9, only 2 months installed and no leak. I have not had to refill or my compressor does not cycle like it has low freon, and it blows ICE COLD

Works great and 1can =1lb for even better value

The car needed a new condenser. The previous owner had loaded the system with leak detector but apparently didn't know you need special equipment to see the leak. We opened the system. replaced the condenser and drier ( About 1/2 full) new orings. closed the system. pulled z134 into the system according to the cross on oz of 134 to z134. The air temperature coming out was 38 degrees F. Do not let the flammability scare you. Most leaks are so small that it isnt a issue. Yes z134 runs at higher pressure. however if your hitting the high limit its because you have other issues ( Blocked orfice?) If you have the equipment to charge your system, you probably understand there are risks to working on your own A/C. use your head and think through the problem before you ruin the environment by dumping r134 into it!

Wow, what a great deal. I knew that I had a small leak from my condenser so I purchased those six cans; while waiting for new CONDENSER to arrived. I wasted two cans, trying to have cold air in my car. After the new condenser was installed. Ac IS COLDβ›„β›„β›„β›„. GREAT BARGAIN !!!

good stuff, on time.next buy is for leak stop r134.
