Gardner Bender Ox-Gard Antioxidant Compound, 1 oz. is a specialized formula designed to prevent oxidation and enhance conductivity in electrical connections. When exposed to the elements or when connecting different metals like aluminum and copper, oxidation can form and create a barrier that impedes electrical flow, leading to poor performance or connection failure. Ox-Gard effectively penetrates aluminum oxide, a common byproduct of aluminum oxidation, helping to maintain clear inter-strand and inter-conductive current paths. This ensures improved conductivity and a reliable flow of electricity. I for use in various electrical connections such as AL/AL, AL/CU, and aluminum conduit joints, Ox-Gard is widely used in electrical installations, repairs, and maintenance to promote optimal performance and extend the life of connections.
