Review on 🔧 1PC Diagnostic Manifold Gauge Kit - Optimized for R134A, R12, R22, R502 Refrigerants | 5FT by William Stewart

Gauges and valves work well. Two disappointments: (1) No R134a 14oz faucet adapter; Threads are not compatible. [This may be a serious fault of the cylinder valve, which is not part of this kit.] (2) The high-pressure connector (red) is not fully inserted into the vehicle connector. [I got the impression it was a small but important manufacturing defect. I solved the problem by buying a separate pair of connectors - connectors with built-in valves that allowed connection to the car's air conditioning service port with the port valve in the "closed" position.]
