Therefore, thestandard diameter of the system service port has changed from 7/16 UNF-20 (1/4 flare) to 1/2 UNF-20 (5/16 flare) in order to prevent systemdamage and personal injury due to mischarging.In addition, most types of refrigerant oil (synthetic oil) which are used for the HFC refrigerant system are different substantially from thetypes of refrigerant oil (mineral oil) which were used for the conventional system. If the two different types of oil are mixed, impurities will beformed causing system damage.If material for the conventional refrigerants is used as material for HFC refrigerant seals, cracks and melting will occur causing 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.BALL VALVE MANIFOLD R410A R32BALL VALVE ASSURES AND ENABLES AN EASY AND ACCURATE JOB.
