R134A Air Conditioning Gas Refrigerant – 12 kg, Rechargeable Cylinder, 1/4" Connection

R134A Refrigerant 12 kg – A Proven Classic for Vehicle Air Conditioning and Refrigeration Systems
R134A (chemical name: 1,1,1,2-tetrafluoroethane, molecular formula CH2FCF3) is a single-component HFC refrigerant of safety class A1 and is considered a direct successor to R12. For many years it has been used in vehicle air conditioning systems, commercial refrigeration, household cooling, chillers and certain heat pumps in the medium- and high-temperature range. At Voll-Gas you get R134A refrigerant with a 12 kg fill weight in a rechargeable cylinder with a 1/4" connection – deposit already incl uded in the price and delivered free of shipping charges within Germany. We ship daily.

The correct fill quantity and a tested product are essential for reliable operation. Our products are tested, quickly available and comply with current safety standards.

R134A as a Successor to R12
R134A was developed to replace the ozone-depleting R12 (CFC) without its ozone depletion potential. As a pure substance (not a blend), R134A has no temperature glide, which simplifies filling and troubleshooting. Its low pressure level and comparatively high boiling point make it the preferred choice for the medium- and high-temperature range – it is not designed for deep-freeze applications.

When retrofitting or servicing, make sure to use the correct lubricant: stationary refrigeration and air conditioning systems typically use polyol ester (POE), while vehicle air conditioning systems usually run on PAG oil. Mixing the two oil systems should be avoided.

Safety, Storage and Disposal
R134A belongs to safety class A1 and is considered non-flammable. Nevertheless, basic safety measures must be observed when handling it. Avoid direct skin contact with liquid refrigerant and work in well-ventilated areas, as released gas can displace oxygen. The safety data sheet contains all relevant information on hazards, protective measures and first-aid measures – read it carefully before use.

The key safety instructions for working with R134A refrigerant:

Ensure ventilation: Work in well-ventilated areas or outdoors
Wear protective equipment: Use safety goggles and gloves when handling
Carry out leak checks: Check connections before and after filling
Observe pressure limits: Never exceed permitted operating pressures
Have an emergency plan ready: Know the first-aid measures for skin contact or inhalation


Store containers upright in cool, dry rooms, protected from direct sunlight and heat sources above 50°C. Disposal is subject to legal requirements for fluorinated greenhouse gases – refrigerant must not be released into the atmosphere.

Voll-Gas – Your Partner for All Types of Refrigerants
At Voll-Gas you get R134A refrigerant in tested quality, delivered quickly and reliably. Besides R134A, we carry other refrigerants for various applications – such as R404A for deep-freeze applications, R407C as an R22 replacement, or R1234YF for modern vehicle air conditioning systems. Our team is happy to help with questions about compatibility, fill quantities and safety information.

FAQ about R134A Refrigerant
Can I mix R134A with other refrigerants?
No, R134A must never be mixed with other refrigerants such as R1234yf. This can cause serious system damage and safety risks. The connection couplings are designed differently for good reason.
