*Stop Leak (Pro-Seal XL4) 


ProSeal XL4 (Leak Stop) is compatible with all refrigerants except ammonia. 


Pro-Seal XL4  performs best in heat pumps, split and mini- split units, packaged units, microchannel coils, coolers, and commercial units.


  • Unlike most other products on the market, ProSeal XL4 Itravels with the gas, which makes it faster, and more effective at finding leaks. 

  • ProSeal XL4 will seal most leaks when used according to the manufacturer’s instructions and will seal most small holes located in the A/C condenser, evaporator, fittings, and metal line sets. 

  • Sealing leaks will save energy and lower refrigerant emissions.

  • Forms a hard seal on metal, schrader valves, o’rings, 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.

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

  • Applications: heat pumps, split systems & mini split units, packaged units, and microchannel coils

  • DO NOT use in ammonia systems

  • No need to pump-down R404a systems.
