FUKKOL WELDGRADE Oxidation Inhibitor (No. 11883) is a high-performance, non-alcohol oxidation prevention agent specifically formulated for HVAC and refrigerationtechnicians. During copper pipe welding and brazing, high temperatures cause rapid oxidation inside the pipe walls, creating scale that damages compressors and valves.FUKKOL WELDGRADE utilizes a heat-induced chemical formulation that generates an inert protective gas barrier inside the pipe during heating. This effectively prevents internal oxidation,replaces traditional bulky nitrogen purging setups, and guarantees high-quality solder joints.
