ZeroR Performance Boost Kit for R1234YF Refrigerant AC Systems | 24" Charging Hose with Gauge | 3 Cans

Perfect kit with Maxdry, Max Seal, and oil Charge. And part of a second kit of 3 R1234YF refridgerant. Both Kits worked great. AC wasnt working and Dealership wanted $1800 to replace the condensor and recharge. I spent 10% of that and now my AC works great and no leaks so far.

Great

DO NOT BUY!1) The gauge on the additive hose is completely busted on both orders from this company. Between both purchased, the gauge shows my system was over pressurized 40+psi over the needed limit in a dangerous pressure zone and bounces all over the place in the red danger zone while the can is attached. In reality it was still under the manufacturer recommended psi with a full set of gauges on high and low sides of the system. You have ZERO chance of measuring how much Freon you're adding to your system without correct gauges which could be extremely dangerous if over pressured and very heavy on the wallet for repairs.2) After vacuuming this "r1234yf" from my entire A/C system and replacing it with a more reputable brand my A/C blows way colder than adding this trashy product.Do yourself a favor and don't cheat yourself with this garbage worthy product!

Works great

Gauge works as it should. Seems like the cans are a quarter filled.

I'd have given it five stars if there was a better seal on the needle valve. My wife's A/C was very low and 2 full cans wasn't quite enough. I had to puncture the 3rd can just to use a little bit. No matter how tight I closed the valve I could still hear the hiss of escaping refrigerant.Almost a full can bled out and went to waste.

Perfect product

Funciona muy bien
