Review on 🔧 LICHAMP AC R1234YF R134A Gauge Set: Efficient Automotive 4 Valve Manifold Gauge for R1234YF and R134A Refrigerants by Warren Hess

Instead of hiring sensors like I've always done, I decided to buy my own set. My wife advised me to order a good set from well-known brands, but I didn't listen because a good set is expensive. I ordered them and they look good but when first used on the r134a the high side connector failed and the oil and coolant mixed throughout the engine bay. A tiny green O-ring flew out of the connector. I managed to find the black o-ring and got back to work. Other issues are the can tap is useless and I had to buy one and the hoses are stiff and keep coming loose at the ends. I use the sensors a couple of times a year so I play around with them but I had to listen to my wife.
