EMI-Shielded O‑Rings and Seals

Reliable Shielding for Electronic Applications

Apple Rubber offers custom-designed, EMI-shielded o-rings and seals for a variety of electronic applications. We provide an alternative to metallic coating of parts and other methods utilized for EMI shielding, while delivering a reliable sealing solution.

Sealing and Shielding in One

Made with conductive, particle-filled elastomers, our o-rings and seals provide high EMI shielding effectiveness in an environmental or pressure seal. The microscopic particles establish a conductive path within the elastomer to create a versatile seal for use in EMI suppression.

Particle fillers include silver, copper, nickel and graphite. Elastomers can be formulated in a range from 7 to .002 resistances in ohms centimeters.
