  • Aerosol
  • Forms a hard seal on metal, schrader valves, o’rings, gaskets, a/c condensers, evaporators, line sets and solder joints
  • Enviro-Safe Proseal repairs minor leaks in systems with and without a fill port
  • Systems without a fill port require the use of a bullet piercing valve
  • Applications: camper refrigerators, R22 window ac units, dehumidifiers, freezers, domestic refrigerators, drinking fountains, etc.
