The Totaline refrigerant safety caps deter refrigerant theft by denying access to refrigerant service ports and are a safety feature designed to guard against the act of inhaling refrigerants, the manufacturer says. The safety caps are color-coded and stamped for easy refrigerant identification with R-22 and R-410A. They require a key for unlocking. The Totaline Totaltest 2 all-in-one refrigerant test kit diagnoses HCFC and HFC systems. Designed to eliminate the need for oil samples, this kit is the only acid- and moisture-testing system of its kind, claims the company. It works without shutting off the compressor. Replacement tubes are available.
