What Is R1234yf?
R1234yf is a hydrofluoroolefin (HFO) refrigerant used primarily in automotive air-conditioning systems.
It was developed as a lower-GWP alternative to R134a and has become widely used in modern vehicle
air-conditioning applications.
Unlike R134a, R1234yf has an A2L safety classification. This means that service personnel
must take the refrigerant's mild flammability characteristics into account when recovering, charging,
storing and servicing systems.
R1234yf for Automotive Air Conditioning
R1234yf is widely associated with modern automotive air-conditioning systems. It is used in vehicle
systems specifically designed or approved for this refrigerant.
The refrigerant should not be selected solely on the basis of similar operating characteristics to another
refrigerant. Always follow the vehicle manufacturer's refrigerant specification and the requirements of
the particular air-conditioning system.
Typical professional applications
- Automotive air-conditioning service
- Vehicle refrigerant recovery and recharge
- Professional automotive workshops
- Service stations equipped for R1234yf
- Maintenance of systems specifically designed for R1234yf
Do not use R1234yf as a universal replacement.
Refrigerants must not be substituted without confirming compatibility with the equipment,
compressor, lubricant, service connections and manufacturer requirements.
R1234yf vs R134a
R1234yf and R134a are different refrigerants and have different safety classifications.
R1234yf is classified as A2L, while R134a is classified as A1.

These refrigerants should not be treated as interchangeable. R1234yf is not a simple retrofit replacement
for R134a; the vehicle or equipment manufacturer's specification must be followed.
Safety and Handling
Because R1234yf is classified as A2L, appropriate precautions are required during storage, recovery,
charging and servicing.
- Use equipment specifically approved for R1234yf.
- Use recovery and charging equipment suitable for an A2L refrigerant.
- Ensure adequate ventilation in the service area.
- Keep the refrigerant away from ignition sources and excessive heat.
- Follow the safety information in the applicable SDS.
- Use the correct refrigerant identifier and service connections.
- Do not mix R1234yf with R134a or other refrigerants.
- Follow the vehicle or equipment manufacturer's service procedure.
Charging and Service Equipment
R1234yf requires service equipment designed for this refrigerant. Professional automotive service
equipment may include dedicated recovery/recycling/recharging machines, leak detection equipment
and refrigerant identification tools.
Before servicing a vehicle, confirm that the equipment is intended for R1234yf and that the required
procedures and safety requirements are being followed.
5 kg R1234yf Packaging
The 5 kg format provides a larger working quantity for professional workshops and
service operations compared with smaller service containers.
The exact cylinder type, valve configuration, tare weight, filling specification and manufacturer
should be confirmed from the documentation supplied with the specific product batch.
Environmental Information
R1234yf has an ozone depletion potential of zero and a GWP of approximately 1.
Its low GWP was one of the reasons for its adoption as an alternative to higher-GWP refrigerants
in automotive air conditioning.
Environmental and regulatory requirements can vary depending on the application and jurisdiction.
Customers should verify the requirements applicable to the equipment and country of use.
Before Buying R1234yf 5 kg
- Confirm that the vehicle or equipment manufacturer specifies R1234yf.
- Confirm that the required service equipment is compatible with R1234yf.
- Check the SDS before handling the refrigerant.
- Verify the product quantity and packaging.
- Check the manufacturer, batch and origin information on the supplied documentation.
- Make sure the refrigerant will not be mixed with another refrigerant.
Product Documentation
For professional use, we recommend checking the documentation supplied with the product before
charging or servicing equipment.
- SDS (Safety Data Sheet) — safety, handling, storage, transport and regulatory information.
- TDS (Technical Data Sheet) — technical properties and product specifications.
- Batch / quality documentation — where supplied with the specific product.
Product-specific values such as purity, filling tolerance, cylinder specification, manufacturer and
country of origin should be taken from the documentation for the actual batch rather than assumed
from generic R1234yf specifications.
