A Closed-Cell Foam Duct Sealing
System for Conduit Sizes up to 2″/50mm
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.
