The DAFA Hi-tack pipe collar

DAFA Hi-tack universal pipe collars are used for sealing the vapor barrier around pipe penetrations.

DAFA Hi-tack® universal pipe collar

DAFA Hi-tack universal pipe collars are part of the DAFA AirStop System and are a patented solution for sealing the vapor barrier around pipe penetrations. They can be attached directly to the vapor barrier—quickly, simply, and securely.
