  • Kit includes:
    • ​1 can Enviro-Safe Proseal
    • 1 each R12 brass hose #3390
  • 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 mobile a/c systems.
  • Works on most mobile applications
  • Applications: automotive, campers, semi-tractor trailers, combines, thrashers, agriculture applications

  • Even though Proseal can form a seal on the schrader valve, when you hook up to it the seal will release and allow you to use the schrader if necessary. If there is still Proseal in the system it will reseal the schrader.
