Product Details
- The Enviro-Safe ProSeal XL4 Inject is a concentrated, easy-to-use direct inject refrigerant leak sealant designed for HVAC systems. This innovative, USA-made product is compatible with all refrigerants except ammonia and is highly effective in heat pumps, split and mini-split units, packaged units, microchannel coils, coolers, and commercial units. It travels with the gas to quickly find and seal most small leaks in A/C condensers, evaporators, fittings, and metal line sets, forming a hard seal on various components including schrader valves, o-rings, and gaskets. This one-time use solution requires no injection hose or caulk gun and helps save energy while reducing refrigerant emissions.
