Review on Charging Shut Off 4000 800 Condition Refrigerant by Thomas Chalecki

return hoses after 3 AC pressure tests. the red hose was leaking at the condenser connection on the high-pressure side. I also got a zero reading on my second AC connector. I then connected my colleagues hoses to the yellow jacketed manifold and got excellent pressure readings using the same device. These hoses are unreliable, not the hoses I intend to use all summer at work
