PROSEAL:
Forms a hard seal on metal, schrader valves, o’rings, gaskets, a/c condensers, evaporators, line sets and solder joints
Enviro-Safe Proseal for R1234YF repairs minor leaks in mobile 1234YF a/c systems.
Only for R1234YF applications
Even though Proseal 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 for R1234YF in the system it will reseal the schrader.
For best results, use Enviro-Safe Prodry for R1234YF BEFORE using the Enviro-Safe Proseal to remove any moisture in your system. Moisture is corrosive and no one wants that in their system!
