PHS Service Grommets - Airtightness Accessories

PHS Service Grommets

PHS Airtightness Grommet

PHS service grommets are made from a strong and flexible EPDM.

PHS service grommets provide a tight, flexible fit that prevents the uncontrolled flow of water vapour and air, allowing for greater airtight levels and prevention of interstitial condensation. They are specifically designed for quick and secure sealing of pipes penetrating both the internal airtight vapour control layer & external waterproof/windtight layer.

PHS grommets are be bonded to the appropriate substrate with PHS Argo tape or another suitable universal joining tape.

The area must be dry, stable and free of dust and release agent.  Folds and kinks must be prevented.

  • Self adhesive collar for sealing openings through the airtight level, e.g. for vapour barriers, sarking membranes. 
  • Before application of PHS service grommets, ensure that the application area is clean, dry, grease and dust free.
  • Adhesion to frozen surfaces isn’t possible. Apply only in the appropriate application temperature.
  • PHS Argo tape provides a permanent bond between the grommet and substrate.
  • If bonding to MDF, precondition the surface with a suitable primer to ensure the best possible bond.
