- This SAE Standard covers reinforced hose@ or hose assemblies@ intended for conducting liquid and gaseous dichlorodifluoromethane (refrigerant 12) in automotive air-conditioning systems. The hose shall be designed to minimize permeation of refrigerant 12 and contamination of the system and to be serviceable over a temperature range of ?C30 to 120 ??(?C22 to 248 ??. Specific construction details are to be agreed upon between user and supplier.1 NOTE-R12 refrigerant has been placed on a banned substance list due to its ozone depletion characteristics. SAE J51 specification will be phased out as new automotive A/C systems are using R134a. SAE J2064 is the Standard for refrigerant 134a hose. For refrigerant 134a use@ refer to SAE J2064. 1 Tests referenced in this specification are laboratory tests@ utilized to establish a performance standard.
