Review on 🌡️ ORION MOTOR TECH AC Gauge Set for R134a R12 R22 R502 - 3 Way Automotive AC Gauge Set with Antishock Gauges, Hoses, Couplers & Adapter - Puncturing Can Tap Freon Recharge Kit for HVAC by Adan Hudson

As others have said, the adapter that came with it will not work with the T-connectors you buy in the store. Threads don't line up. You are dead in your tracks. So you should be more clear about the fact that the included adapter doesn't work. The second surprise was that the gauges are in Celsius, not Fahrenheit. I may not have noticed this when I ordered it so make sure you order the correct type you need. I was contacted by Mfg for my two complaints: I needed the Celsius version, it's my fault as stated in the product description - just make sure you see it. The T-connector adapter on the gas cylinder is not supplied with the product, and the product has a standard 134a thread. The tees for the 12 ounce gas canisters commonly found at car dealerships are different. Because of this inconvenience, the manufacturer partially refunded my money without asking. This company stands behind their product and their customers. In addition, I have been using the sensors under constant pressure for a few days now and I am very satisfied with the product. Unlike other sensors I've bought from HarbourFreight in the past (junk that leaked), these just keep getting better. Changing my score from 3 to 5
