Parker Chomerics has developed and enhanced virtually every aspect of conductive elastomer materials technology, from the earliest silver and silver-plated copper filled silicones, to the latest and more cost-effective silver-plated aluminum and nickel-plated graphite composites. Today we offer the most comprehensive selection and highest quality products available.

Parker Chomerics Mushroom-D Shape Electrically Conductive Elastomer Extruded Gaskets are available in various CHO-SEAL® conductive elastomers, consisting of a silicone, fluorosilicone, EPDM or fluorocarbon-fluorosilicone binder with a filler of pure silver, silver-plated copper, silver-plated aluminum, silver-plated nickel, silver-plated glass, nickel-plated graphite, nickel-plated aluminum or non-plated graphite particles.

This item is sold as cord stock and quote cart quantity is in 1-foot (305 mm) increments.

CHO-SEAL® Electrically Conductive Elastomer Extruded Gaskets are reliable over the life of the equipment. The same gasket is both an EMI shield and an environmental seal. Elastomer gaskets resist compression set, accommodate low closure force, and help control airflow. Parker Chomerics offers hundreds of standard extruded products, readily lathe-cut into washers, spliced, bonded, kiss-cut, or die-cut to reduce installation labor and to conserve material, resulting in a cost-effective alternative to other methods of EMI shielding and environmental sealing.
