Electrical Insulator Gaskets and Shields

Electrical insulators serve as a barrier to restrict the flow of electrical current between electrical conductors. They isolate electrical circuits from people and other components and ensure safe operating conditions.

Electrical insulators are manufactured from materials which restrict the flow of an electric current. They support electrical conductors without passing the current through. These materials also protect electrical conductors from encountering people or tools and provide excellent insulation for electrical applications. Jefferson Rubber Works, Inc. insulators and shields are constructed from RoHS compliant materials. Both UL 94 VTM-0 and UL 94 V-0 approved products are available. Resistance to a wide range of chemicals along with low moisture absorption makes the application of these products ideal for printed circuits.

All our products are manufactured from the highest quality materials within specified tolerances and to exacting safety standards.
