Opteon™ YF

Automotive Refrigerant (R-1234yf)

Product Information

Additional Information

Opteon™ YF (R-1234yf) is a non-ozone depleting, low
global warming potential (GWP) refrigerant that was
initially developed to meet the EU Mobile Air Conditioning• Opteon™ YF is compatible with POE lubricants and PAGs
that have been formulated specifically for use withR-1234yf.

(MAC) Directive, which called for new automobiles to use• Opteon™ YF cannot be used for retrofit applications.

refrigerant with a GWP of less than 150, and has since• Opteon™ YF may require additional safety measures

become the standard refrigerant for the majority ofautomotive manufacturers globally.

during implementation, use, and service compared toR-134a, due to its A2L classification.
• Opteon™ YF will require the use of accessories andASHRAE #: R-1234yf or HFO-1234yf

toolings that meet the following standards:

ASHRAE and ISO817 Safety Rating: A2L– Recovery/RRR equipment: J2843, J2851, and/or VDA

Benefits– Leak detectors: J2913 and/or VDA• Non-ozone depleting hydrofluoroolefin (HFO)– Refrigerant identifiers: J2927 or J2912 and/or VDA– Not subject to phaseout under Montreal Protocol• Low GWP refrigerant• Performance and operating characteristics similar toR-134a• Cooling capacity and energy efficiency similar to R-134a– Evaporators: ISO 13043 and/or SAE J2842

A2L Refrigerant Information
R-1234yf has an A2L ASHRAE classification. A2L
refrigerants are described as low or mildly flammable insimplistic terms; however, they are difficult to ignite.
Assessment of properties, such as minimum ignition• Thermally stable under extreme use conditions
