R1234YF Refrigerant for Car Air Conditioning – 10 kg Refillable Cylinder – 1/4" Connection

R1234yf Refrigerant – The Binding Standard for Air Conditioning Systems in New Vehicles

R1234yf (2,3,3,3-tetrafluoropropene) is an HFO refrigerant specially developed as a replacement for R134A in vehicle air conditioning systems. It complies with the strict EU requirements for mobile air conditioning systems (MAC Directive 2006/40/EC) and has been the binding standard in all newly registered cars and light commercial vehicles in the EU since 2017.

Where is R1234yf used?

R1234yf is used in the air conditioning systems of almost all new passenger cars in the EU. Its thermodynamic properties are deliberately kept similar to R134A, so it can be used in many R134A-designed air conditioning systems without major technical changes. The air conditioning circuit (compressor, condenser, dryer, expansion valve, evaporator) remains identical.

With a GWP value of approximately 4, R1234yf is about 358 times lower than R134A (GWP 1,430) and decomposes in the atmosphere after only 10 to 12 days.

Important Safety Notice: Flammability (A2L)

R1234yf is classified as a mildly flammable gas in safety class A2L. It forms flammable gas-air mixtures and requires special workshop equipment with explosion protection and refrigerant identification. From a safety perspective, a direct replacement of a non-flammable refrigerant (R134A) with R1234yf in an existing system without appropriate adjustments and checks is not permissible. Mixing or improper conversion is generally excluded, as seals, connections, and safety valves are not compatible.

Legal Situation and Availability

Since January 1, 2017, R1234yf has been mandatory for all newly registered cars and light commercial vehicles in the EU. As it is not subject to any significant quantity restrictions under the F-Gas Regulation, pricing is significantly more stable and predictable compared to R134A.

Professional Filling and Service

The filling of an air conditioning system with R1234yf should always be carried out by trained specialists with the appropriate certification. The process includes extracting and recycling the old refrigerant, a vacuum test of at least 30 minutes, and precise refilling according to the manufacturer's specifications in grams.

Frequently Asked Questions about R1234yf

Can I mix R1234yf with R134A or simply convert R134A systems?

No, mixing or improper conversion is excluded. Seals, connections, and safety valves are not compatible, and any conversion must always be carried out by specialist personnel, taking safety requirements into account.

Is R1234yf flammable?

Yes, R1234yf belongs to safety class A2L and is considered mildly flammable – unlike R134A.

What advantages does R1234yf offer over R134A?

R1234yf offers an extremely low GWP of around 4 compared to 1,430 for R134A – a reduction by a factor of 358 – with comparable thermodynamic properties.
