Review on AutoWanderer Tool Conditioning Diagnostic Refrigerants by Michael Bryan

That would be great if everything works. Unfortunately the set I received had a defective faucet which punctured and destroyed the entire self sealing valve. Also, the glass faucet doesn't seal well and will leak no matter how you position or tighten it. So I went to my local auto parts store and bought a new faucet. Unfortunately, the thread size on the gauge set is different and does not correspond to the standard of other common gauge sets! So I go back to auto parts and get a set of AC sensors from them (I didn't know they rented them). A bit worn but everything worked and charging was easy! If so, see if you can knock.
