Glo Leak/UV Dye – GL1234

Glo-Leak/UV Dye – GL1234

For new R1234yf as well as R134a & Hybrid systems:

Glo-Leak 1234 is for R1234yf and is specially formulated to mix with the new refrigerant. Just as additional special processes are required to produce PAG lubricants for R1234yf, the same is true of this new Glo-Leak formulation. Like the R1234yf PAG oils, Glo-Leak 1234 is backward compatible with R134a and other refrigerants, but not vice versa.
