REFRIGERANT: The cartridge itself is refrigerant-independent brass hardware. Refrigerant is set by the thermostatic element it is paired with: KT-43 for the R-22 family, KT-45 for R-410A. What DOES change with refrigerant is the cartridge capacity, listed below. IMPORTANT FITMENT: BQC cartridges fit balanced-port bodies only, meaning types BQ, BQE, EBQ, EBQE, SBQ and SBQE. They will not fit the conventional-port Q, EQ or SQ bodies, which use QC-series cartridges. Types Q, EQ and SQ are not approved for R-410A at all. R-410A elements are approved for BQ, EBQ and SBQ bodies only.
