 Enviro-Safe ProSeal VS (293 KB, PDF)

  • 1 can of Enviro-Safe ProSeal VS will treat 1 vehicle.
  • Vacuum sealed
  • Forms a hard seal on metal, schrader valves, orings, gaskets, a/c condensers, evaporators, line sets and solder joints
  • Enviro-Safe ProSeal VS repairs minor leaks in R12 & 134a automotive a/c systems
  • Even though ProSeal VS 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 VS in the system it will reseal the schrader.
  • For best results, use Enviro-Safe ProDry VS BEFORE using the Enviro-Safe ProSeal VS to remove any moisture in your system. Moisture is corrosive and no one wants that in their system!
