DeoxIT D-Series contact treatment is a fast-acting deoxidizing solution that rejuvenates, lubricates, protects and improves conductivity on all metal connectors and contacts. Use as a general treatment for connectors, contacts and other metal surfaces, and on non-critical metal surfaces with severe oxidation and corrosion. If the metal surface is discolored, it is severe. DeoxIT dissolves the contamination and protects the surface.Main Features:Improves ConductivityDeoxidizes, Lubricates and ProtectsReduces Intermittent ConnectionsReduces Arcing & RFIReduces Wear & Abrasion* Temperature Range, -34 C (-29 F) to +200 C (400 F)(* NOTE: Temperature ranges may vary depending on conditions.)
