Therefore, the standard diameter of the system service port has been changed from 7/16 UNF-20 (1/4 flare) to 1/2 UNF-20 (5/16 flare) inorder to prevent system damage and personal injury due to mischarging.In addition, most of the types of refrigerant oil (synthetic oil) which are used for the HFC new refrigerant system are different substantiallyfrom the types of refrigerant oil (mineral oil) which were used for the conventional system. If the two different types of oil are mixed,impurities will be composed to cause system damage.If material for the conventional refrigerants is used as material of HFC refrigerant seals, cracks and melting will occur to cause gas leakage.It is necessary to use HFC-proof HNBR or material coated with a special type of nylon.R410A refrigerant is a blend of R125 and R32. Basically, it should be charged in a liquid phase in order to avoid composition change.R410A/R32 BALL VALVE MANIFOLDBALL VALVE ASSURES AND ENABLES A EASY AND ACCURATE JOB.
