Single Wire Seals and Cavity Plugs

TE Connectivity single wire seal (SWS) are a rubber element with three interfaces wire, contact and cavity. The TE Connectivity cavity plug is used to seal a cavity where no contact is used. The geometrical profile is fully from the single wire seal element with the exception that it does not have an inner hole for wire.

Wire seal and cavity plugs

Key benefits

  • Cavity Plug - ShA hardness range between 50 and 60

  • Seal to wire interface - Multiple sealing surface

  • Seal to contact interface - The contact barrels close and retain the SWS without generating cuts on the surfaces

  • Seal to cavity interface - Most single wire seal designs use a three-lip configuration creating three layers of redundant sealing
