Pro-TekĀ® 922 is a concentrated corrosion inhibitor treatment specially formulated for hot water closed loop heating systems. Many water sources used in hydronic heating systems can be very corrosive to metals when heated. Pro-Tek 922 will help to reduce corrosion on aluminum, brass, copper, iron, and stainless steel. Pro-Tek 922 has also been tested and is compatible with standard PEX and Onix tubing typically used in hydronic installations.
