Refrigerant Gas R402A


R-402A is an HCFC-based service refrigerant that meets the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) Safety Grade A1 (the highest level, which is not harmful to human health) and meets EPA, SNAP, and UL standards. R402A is a safe, effective and convenient solution to replace R502 refrigerant when replacing refrigerant in aftermarket refrigeration equipment.


R402A Refrigerant steel cylinder is a pressure container. It should be kept away from fire, heat and direct exposure to sunlight. It is usually stored in a cool, dry and ventilated warehouse. When handling, light loading and unloading should be carried out to prevent cylinder and valve and other accessories from damage.
