R-407C is approximately 10% higher.
These refrigerants use ether oil for refrigerant oil instead of suniso oil. If oil of an incorrect type is
mixed in R410A and R-407C, sludge results in the refrigerants and causes equipment problems.
Therefore, gauge manifolds and charge hoses that are used with a previous refrigerant (R22)
cannnot be used for products that use new refrigerants.
Be sure to use dedicated tools and devices.
