4-8mm SIGA Fentrim Grommet White - Self‑Adhesive EPDM Grommet - Box of 20

Pack Quantity: 20

4-8mm SIGA Fentrim Grommet White is a robust, self‑adhesive EPDM grommet designed for quick, airtight sealing of circular penetrations such as pipes and cables. It delivers immediate 100 % tightness, extremely high adhesive strength at both high and low temperatures, and a plasterable fleece/film collar for clean integration into interior airtight layers. SIGA Fentrim Grommet White is engineered for airtight sealing of penetrations through vapour control layers, wood‑based panels, and other interior airtightness substrates. The flexible EPDM body forms a tight seal around the pipe or cable, while the special fleece/film collar—coated with SIGA’s high‑performance adhesive—bonds securely to the surrounding airtight layer and can be plastered over where required.

The grommet is tear‑proof, highly flexible, and designed to accommodate structural movement without losing airtightness. A slit backing strip speeds up installation and prevents damage during fitting. SIGA Fentrim Grommet White is a high‑quality, durable airtight grommet offering fast installation, exceptional adhesion, and reliable long‑term performance for sealing circular penetrations. Its EPDM construction and plasterable collar make it ideal for achieving airtightness in modern interior construction.

CHARACTERISTICS

  • Airtight penetration sealing - immediately 100 % tight around pipes and cables. 
  • Flexible EPDM construction - robust, weather‑ and ageing‑resistant material. 
  • Plasterable fleece/film collar - integrates cleanly into interior airtight layers. 
  • High‑performance adhesive - extremely strong adhesion at high and low temperatures. 
  • Fast installation - slit backing strip saves time and prevents tearing. 
  • Durable performance - absorbs building movement reliably over time.

APPLICATION

  • Cable penetrations through vapour control layers
  • Pipe penetrations in timber or masonry construction
  • Interior airtight layer detailing
  • Plasterable airtight junctions
