HK5NG Premium Refrigerant Charging Hoses

Each hose features a patented, “T” shaped, SafeMate™ valve and fitting on one end, and an open, straight fitting on the other.
The T-shaped SafeMate™ valve has a screw-down core depressor that activates refrigerant flow after the knurled brass fitting has been fully tightened onto a service port. This protects technicians’ hands from frostbite and prevents refrigerants from escaping into the atmosphere.
Once attached, the innovative T SafeMate™ valve swivels above the brass nut so it won’t loosen if a hose is moved during charging, recovery, or evacuation procedures.
