Temperature scale indicates the relationship between pressure and temperature in gas
saturated state.
Change in pressure
Change in service port diameter
Working pressure 5.08 MPa (51.8 kg/cm
Rupture pressure 25.4 MPa (259 kg/cm
Available with and without hand-operate valve that prevents refrigerant from outflow.
Pressure proof hose
Change in service port diameter
Use of nylon coated material for HFC resistance
Use weigher for refrigerant charge listed below to charge directly from refrigerant cylinder.
The cylinder can not be used for mixed refrigerant since mixing ratio is changed during
charging.
When R-410A is charged in liquid state using charging cylinder, foaming phenomenon is
generated inside charging cylinder.
