Suitable for Refrigerant Classes A1-A3. Refer to instructions for specific refrigerants.

Key Features
  • All Hoses Feature - A solid brass "T" shaped SafeMate Valve on one end, and an open, straight Brass Valve Nut on the other.
  • SafeMate Valves - Have a screw down core depressor that activates refrigerant flow after the Brass Valve Nut has been fully tightened onto a service port. This prevents refrigerant from escaping into the atmosphere.
  • Red, Yellow Or Blue Offset Knobs - Keep hands away from the service port and help prevent refrigerant burns.
  • Swivel "T" Valve - Once attached, the innovative T valve swivels above the Brass Valve Nut so it won’t loosen if a hose is moved during use.
  • Hose Barrier Lining - Minimizes refrigerant loss vs conventional hoses.
