Review on 🔧 3-Way AC Diagnostic Manifold Gauge Set for Efficient Freon Charging: Compatible with R134A R12 R22 and R502 Refrigerants. Includes 3FT Hose, Acme Tank Adapters, Quick Couplers, and Can Tap by Johnny Murphy

This set is worth the money. I can't swear it's correct. I didn't see enough vacuum on the gauge and I tapped it and it jumped two more readings. I tapped it frequently to make sure I was seeing the right ad. The anti-slip device for the low-pressure side slipped off the first time I used it. I had to be very careful when connecting to the low pressure side to keep it from slipping off the line. I would recommend removing the R134 fittings and storing them in a case in case the gauges are not being used, there are no caps for these fittings in the kit. In the end I was able to evacuate and recharge my system myself and the savings I had to pay for it were worth it. I learned how to do it by watching some YouTube videos. It turned out great.
