These gaskets absorb electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent inaccurate signals, flickering displays, and other electrical problems. They compress to fill gaps and complete a grounding path around doors and access panels.

Adhesive-back gaskets are wrapped with conductive aluminum foil and stick on with a conductive adhesive. Plain-back gaskets are made with conductive silver wire.

Beryllium copper gaskets withstand repeated compression and decompression over time, so they’re often used with doors that regularly open and close. They’re also known as fingerstock gaskets. Adhesive-back gaskets stick to flat surfaces. Install clip-on gaskets onto surfaces such as circuit board edges or enclosure door frames.
