R134A (Tetrafluoroethane)

R134a is one of the most common refrigerants used in a wide range of refrigeration and air conditioning applications, including medium and high temperature refrigeration (both domestic and commercial), residential & light air conditioning, automotive air conditioning and industrial applications such as centrifugal chillers. It is also a common component in many HFC refrigerant blends and is used in some propellant applications. Can be used as a retrofit in some R12 and R22 applications with an oil change. Low-GWP replacements include R1234yf, R1233zd, R1234ze.


It is used as a pure gas or as a component with other refrigerant gas mixtures in:

  • Comfort cooling in vehicles.

  • Medium temperature commercial refrigeration.

  • Refrigerators.

  • Dehumidifiers

  • Refrigeration of transport equipment.

  • Commercial Refrigeration: Plug-ins & Vending Machines

  • Industrial Refrigeration

  • Residential & Light Air Conditioning

  • Industrial / Commercial Air Conditioning DX Chillers

  • Industrial / Commercial Centrifugal Compressors

  • Mobile Air Conditioning

Product Features and Benefits

  • Substitute for R12, with comparable physical and thermodynamic properties

  • Refrigerant can be charged from either the liquid or vapor phase

  • PVCK refrigerant cylinders have dual port valves, making liquid offtake easier

  • Non-flammable with a safety classification of A1

  • Compressors must be charged with polyester oils, contact the compressor manufacturer for more information

  • Reduction of capacity compared to R12

  • Existing R12 equipment can be retrofitted with R134a

  • High critical temperature which ensures good coefficient of performance

For optimal performance and compatibility, PVCK recommends the use of valve fittings that have plastic sealing washers (e.g. Nylon, PTFE or PCTFE) for refrigerant products. Hard or inflexible materials such as fiber washers may cause minor connection leaks. The sealing washer should be visually inspected for damage or wear before each use. Fittings should be installed slightly tighter than hand-tight.
