Super Lube Silicone Dielectric & Vacuum Grease Non Curing Compound (Translucent White, 14.1oz 400g Canister) Sanders & Planers Garvin' heavy gauge steel construction Garvin' heavy gauge steel construction maintains mechanical protection and solid grounding of the conduit to the designated electrical junction box or enclosure which can be tied in knots without any risk of ruining or reducing flexibility PREVENTS ELECTRICAL ARCING – Dielectric and vacuum greases are formulated with highly insulating properties that prevent electrical arcing and short circuits by filling microscopic air gaps between electrical components and surfaces operating at high voltages or in a vacuum environment enabling it to resistantly insulate and prevent arcing or tracking between electrical components operating at high voltages
