Silicone Dielectric and Vacuum Grease, 3 oz Tube, NLGI Grade 2, NSF Rating H1

Specially formulated non-curing silicone compound that exhibits superior performance in both electrical and vacuum applications. Seals, protects, and insulates electrical components and connectors. Waterproof and provides a barrier against moisture and other contaminants in many types of electrical contact points. Helps reduce the overall leak rate in vacuum applications by filling the spaces of the gland's surfaces and lowering permeation rates of the elastomer.
