ProSealXL4


One of our most requested products!


Enviro-Safe® ProSeal Xl4 


Refrigerant leak sealant.  


ProSeal XL4 Inject is compatible with all refrigerants including R410a.


ProSeal XL4 performs best in air-conditioning systems especially the new R410a Mini-Splits.


Also heat pumps, split and mini- split units, packaged units, microchannel coils, coolers, and commercial units.


Enviro-Safe™ has been producing and packaging sealants for over 17 years. 



  • Unlike most other Stop Leaks on the market, ProSeal XL4 travels with the refrigerant, which makes it faster, and more effective at finding and sealing leaks. 

  • ProSeal XL4 Inject 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.
