The 30-030 is Noalox® Anti-Oxidant Compound supplied in an 8 oz. squeeze bottle, designed to protect aluminum electrical connections from oxidation and seizing. The compound contains suspended zinc particles that penetrate and cut through aluminum oxide layers, while the carrier material excludes air to prevent further oxidation. It reduces galling and seizing on aluminum conduit joints and improves the service life of aluminum electrical applications. The product is compatible with all types of pressure-type wire connectors and is commonly used in electrical installations where aluminum components require long-term corrosion protection and reliable joint performance.
