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. This allows for greater airtight levels and prevention of interstitial condensation. They are specifically designed for quick and secure sealing of pipes that penetrate both the internal airtight vapor control layer and the external waterproof and windtight layer.
Bond PHS grommets to the appropriate substrate using PHS Argo tape or another suitable universal joining tape.
