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.

For optimal performance and compatibility, BOC 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 fibre 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.

• Typical lubricant: Polyolester (POE), Polyalkylene glycol (PAG)
• GWP: 1430; ODP: Non-Ozone Depleting
• Boiling point: -26°C; Critical point: 101°C
• Glide: Nil
• Critical pressure: 41 bar
• Can be charged in liquid or vapour phase. High critical temperature ensures a good coefficient of performance.
