  • Finds and seals leaks in ac systems
  • 1 can of Enviro-Safe 1234YF ProSeal with Leak Detector will treat 1 vehicle.
  • Forms a hard seal on metal, schrader valves, o’rings, gaskets, a/c condensers, evaporators, line sets and solder joints
  • Even though Proseal with Leak Detector for R1234YF 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 with Leak Detector for R1234YF in the system it will reseal the schrader.
  • Proseal with Leak Detector for R1234YF uses a precisely selected, fluorescent-yellow dye that is highly visible and is the same dye used by auto makers in car A/Cs
  • While the dye is highly visible, and in most cases, able to be seen with the naked eye, the use of a blacklight as well as UV glasses does make it much more visible.
  • Before replacing expensive parts and labor, try Enviro-Safe Proseal with Leak Detector!
