Review on Aupoko Refrigerant Self Sealing Condition Charging by Sean Tops

This was exactly as advertised and worked great for connecting to the bottom port of my air conditioning on my 2017 Civic hatchback and to the R1234yf refrigerant tank which needs to be filled up. Although I've read other reviewers reminding users that the faucet is left-hand threaded, of course I forgot about this until I figured out why the faucet couldn't be screwed on. Remembering the reviews, it was a perfect fit. Putting some kind of sticker on the hose or faucet to remind users would probably be helpful. But that's my only complaint. This is one of the more affordable options for that proprietary hose, so I'm happy with it and hope I never have to use it again because that #$! & expensive is @ $45 for 8 ounces. Allowed to!
