REFRIGERANT 134A 3KG is a refrigerant gas commonly used in air conditioning and refrigeration systems. As a hydrofluorocarbon (HFC), it does not damage the ozone layer like older refrigerants but has a higher global warming potential than other more sustainable options. This 3KG cylinder contains enough R134a refrigerant to service medium-sized residential and light commercial HVAC systems. The refrigerant is a clear, colorless liquid and vapor with a faint ethereal odor. It is non-flammable and non-toxic but still should only be installed and recovered by a certified technician. Check for leaks and make sure your system is properly sealed before charging to ensure peak cooling performance.
