“Just over the phone, they identified what the problem was and made a solution for it. Quell was really incredible. Their expertise, their help, it was critical.”

How it Works

The silicone elastomer body of EESeal® slides over a connector’s existing pin layout like a glove.
Compression takes it from there: EESeals can change shape, adapt to misaligned pins, all while maintaining a snug environmental seal.

  • 360º conductive silicone contact around each pin
  • Multiple conductive silicone peripheral shell contacts
  • Individual components and interconnections move as the body changes shape
  • Body acts as conformal coat and electrical isolation for suspended components
