Kroil 91003 Silicone Dielectric Vacuum Grease 3 Oz

Product Description

The KROIL 91003 is a non-curing silicone dielectric and vacuum grease formulated for sealing, protecting, and insulating electrical components and connectors. It performs reliably in both electrical and vacuum applications, making it a versatile compound for HVAC technicians, electricians, and plumbers working on connector maintenance and service. The grease is waterproof and creates a barrier against moisture, corrosion, and contaminants at electrical contact points. With a wide temperature rating of -40 degrees F to 500 degrees F and a flash point of 572 degrees F, it holds up across a broad range of operating environments. Packaged in a 3 oz tube for easy, controlled application.

This silicone grease is suited for residential and light commercial electrical service work. Common applications include weatherproofing electrical connectors, lubricating rubber gaskets and O-rings in plumbing and HVAC assemblies, sealing spark plug boots, and protecting terminals from oxidation and moisture intrusion. It is non-flammable and carries a mild odor, making it practical for use in enclosed mechanical rooms and tight service areas. HVAC technicians, electricians, and plumbers routinely use this type of compound during routine connector maintenance and component replacement.

Installation Notes

De-energize all circuits and confirm power is off before applying grease to any electrical connector or terminal. Apply a thin, even coat to contact surfaces using a clean applicator to avoid contamination. Electricians should follow NEC guidelines when servicing electrical components. Avoid over-application on tight-tolerance fittings, as excess grease can attract debris.
