R1234yf Refrigerant Gas in Ross Dependency, Propeller Shaft Alignment Dial Indicator Stands - Refrigeration Gases

R1234yf is a next-generation, low-global-warming-potential (GWP) refrigerant gas designed as an eco-friendly alternative to R134a. It is widely used in automotive air conditioning and commercial refrigeration systems due to its minimal environmental impact. The gas is non-ozone-depleting and complies with stringent environmental regulations like the EU F-Gas Directive.
