One of our most requested products, Enviro-Safe® ProSeal Xl4 Inject is a small, concentrated, easy inject refrigerant leak sealant. 

This product is currently available in three sizes: Fractional-1.5 ton system, 1.5- 5 ton system, and 6-30 ton system. 

ProSeal XL4 Inject is compatible with all refrigerants except ammonia. 

This product performs best in 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. 

Our Sealant Injector hose was designed and tested during 2013/2014 and has been produced and marketed under private label since the fall of 2014.

Unlike most other products on the market, ProSeal XL4 travels with the gas, which makes it faster, and more effec- tive at finding 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.


*DO NOT use in ammonia systems.

Eliminate the tedius, and time consuming process of "pumping down the unit".

Stop paying for costly annual refrigerant fill ups!

Simply Connect and Inject.
