Refrigerant 12 Automotive Air-Conditioning Hose

2015-04-21
CURRENT
J51_201504
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 −30 to 120 °C (−22 to 248 °F). 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.
