EMI-Shielded O-Rings & Seals

Apple Rubber Products offers custom designed, EMI-Shielded O-rings and seals for a variety of electronic applications. Apple Rubber provides 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.

The solution for a variety of applications.

Our EMI-Shielded seals are designed to provide a conductive interface/seal for applications in a variety of industries including:

• Telecommunications
• Military
• Medical
• Aerospace
• Automotive
• Consumer and industrial electronics
