Non-cooled mixed refrigerants are essential to fill in liquid. Comes standard with sight glass for refrigerant fluid management In addition, it uses a needle gasket valve for new high-pressure refrigerants for improved safety and workability. This is a manifold that can be used with both heating and cooling conditions, so the pressure value of the low pressure side pressure gauge has been set to high pressure, so that you can measure the operating pressure when heatering. Manifold main unit: High pressure needle gasket; Gauge mounting screw: 1/8NPT; Connection port: 1/4 flare; Sight glass included (TA124F-11); Charging hose; Valve included; Connection diameter: 1/4 flare; Normal pressure: 5.5MPa pressure gauge/compound gauge ◇R404A, R407C, R507A, R134a refrigerant Temperature scale included Includes 0 point adjustment function. *Gauge manifold kit has high precision, inspection certificate (lot certification). Charge Hose (TA135AB): 59.1 inches (150 cm), Red, Blue, Yellow, Pressure Gauge (TA140C): -0.1 - 3.8 MPa Compound Meter (TA141C-1): -0.1 - 3.8 MPa
