This product combines our ProSeal XL4 & ProDry XL4 into a direct inject hose for an easy to use, one step application that seals leaks and removes moisture in your system.

Forms a hard seal on metal, schrader valves, orings, gaskets, a/c condensers, evaporators, line sets and solder joints

Even though ProSeal XL4 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 XL4 in the system it will reseal the schrader.

Enviro-Safe ProDry XL4 contains a dehydrating agent that converts system moisture into oil.

This product performs best in heat pumps, split and mini- split units, packaged units, microchannel coils, coolers, and commercial units.
