R-422B (NU-22) Refrigerant 25 LB is a refrigerant that can be used to replace R-22 in air conditioning (AC) systems. It’s a blend of R-22 and other refrigerants that has similar operating characteristics and pressures to R-22. R-422B is non-ozone depleting, nonflammable, and has an ASHRAE A1 classification.

R-422B refrigerant is the ideal choice for industries, commercial businesses, property owners, and anyone seeking an alternative to R-22 for their air conditioning (AC) systems. Unlike certain replacement refrigerants, R-422B  eliminates the need for a time-consuming oil change, making it compatible with all standard oils, equipment components, and materials used in R-22 systems.
