Freon™ 407C (R-407C) is a R-22 replacement primarily for air-conditioning. It's a HFC blend that requires a POE lubricant.

R-407C is included in the U.S. EPA SNAP de-listing of HFCs that will no longer be acceptable in new equipment in certain end use applications in the U.S. market.

A blend of R-32, R-125, and R-134a that 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.

For a no-oil change R22 replacement, check out Freon™ MO99.
