ZipSeal Duct Sealant is a practical and efficient way to seal small conduits and communication innerducts. The revolutionary Zip-Disc insert traps and keeps the foaming liquid in its open-cell (center) area.

The unique two-part foam installs quickly and effectively. The innovative design of the Zip-Disc insert allows for horizontal and vertical installation with minimal drippage. Cured foam blocks can be removed and re-entered relatively quickly if necessary.

ZipSeal Duct Sealant holds up to 10 feet (3.0 m) water-head pressure to keep gases and rodents out of conduits.

Polywater® ZipSeal is recommended for small conduits and communications innerduct applications.  It comes in a side-by-side 50 ml cartridge with a 1:1 mixing ratio.  A TOOL-50-11 is needed to apply the ZipSeal 2-part foam.

Each kit comes with all the components required for a quick, yet strong duct seal, including the unique Zip-Disc for fast and easy application.
