Refrigerant 407C

  • Closest property to match R-22 in a/c retrofit projects
  • Can be used in medium temp R-22 refrigeration systems
  • A blend of R-32, R-125, R-134A
  • Available in 25 lb. Cylinders

R-407C has very similar properties to R-22 in air conditioning equipment. R-407C has the closest property match to R-22 in an air conditioning retrofit project compared to other blends on the market. It can also be used in medium temp R-22 refrigeration systems. R-407C has a 10°F temperature glide. New systems built with R-407C must have POE lubricants, and retrofitted R-22 systems would need the residual oil flushed with POE.


Always wear recommended personal protective equipment.

Avoid breathing vapors and liquid contact with eyes, skin or clothing. Do not puncture or drop cylinders, expose them to open flame or excessive heat. Use authorized cylinders only. Follow standard safety precautions for handling and use of compressed gas cylinders.

R-407C should not be mixed with air above atmospheric pressure for leak testing or any other purpose.

Store in a cool, well-ventilated area of low fire risk and out of direct sunlight. Protect cylinder and its fittings from physical damage. Storage in subsurface locations should be avoided. Close valve tightly after use and when empty.
