Precured Gel Grommets and Sealing Strips


Seal electrical connectors and components

Dow Corning® brand GT precured silicone gel grommets and sealant strips offer you easy-to-use, high-performance sealing solutions for electrical connectors and automotive electronic components.

Innovative procured silicone gel grommets and sealing strips


Improve connector sealing reliability with self-healing silicone gels

Dow Corning GT precured gel grommets and sealant strips are unique as high-performance sealing materials because of their ability to conform, coat and self-heal, yet be easily re-entered.

  • Choose connector grommets (sealant pads) for sealing individual pins, wires and contacts in multi-way connectors and cable entries.
  • Choose sealant strips for sealing and corrosion protection on automotive sensors and connector housings and for low-pressure component gaskets.

Precured Gel Grommets (Sealant Pads)for electrical contact and wire seals

  • Cold applied precured silicone gel; laminated with a top and bottom layer; supplied in rolls or in custom precut shapes
  • Three-layer laminate; middle layer is a thick, soft silicone gel, the top and bottom layers allow easier handling
  • Form a tight environmental seal; readily conform and are re-enterable; available in soft form for minimum insertion force or firmer form for better overall handling

Precured Gel Sealant Stripsfor sealing and corrosion protection

  • Cold applied silicone gel requires no curing; supplied on rolls or in custom precut gasket shapes
  • Soft tacky precured gel available unbacked, Teflon®-backed, rubber-backed, or open-cell foam-backed; flame retardant versions also available
  • Form a tight environmental seal; prevent corrosion; do not require heat or special tools to apply; allow easy inspection or repair
