The Xpress Seal formula is the only proven refrigeration sealer on the market with 17 years and millions of leaks permanently sealed. Other sealants that are just now entering the market have no proven track record. Do you want to take that chance?


Xpress Seal is the fastest refrigerant sealant on the market. Unlike other products, Xpress Seal travels with the refrigerant gas while other products travel with the oil. This allows the sealant to find and permanently seal the leaks faster. And if there ever comes a time that the system needs to be opened up, after it is evacuated, there won’t be sealant hardening in the lines and valves. Xpress Seal’s ultra-concentrated formula will permanently seal small holes located in A/C condensers, evaporators, fittings, and metal line sets. Perfect for split system, heat pumps, microchannel coils, packaged units, and mini splits. Xpress Seal is compatible with all refrigerants except ammonia.


Xpress Seal is an epoxy that reacts to water and air when coming in contact with the atmosphere where it is leaking. If the system stays charged for one day when running, Xpress Seal will fix most leaks. If a system has not leaked below 15 psi, there is typically not air or moisture in the system. If there is air and water in the system, pull a deep vacuum on the system and boil moisture out of the system. An alternative to pulling a vacuum is to use Vapco’s direct inject Xpress Seal Dry and turn the moisture into synthetic oil. This will prevent Xpress Seal from reacting inside your system.


From a safety stand point, Xpress Seal doesn’t contain chemicals that can cause permanent blindness. Also, the direct inject tubes are designed with safety in mind. There are check valves inside the tubes to prevent accidental release if hooked up incorrectly or over pressured.
