FST™ Duct Sealant - Leak Repair Kit
Part No: FST-250KIT1
FST™ Duct Seal is a “closed cell foam”, which is superior to “open-cell” spray canned foams. The kit contains a cartridge filled with a two-part foam base, which is mixed in equal parts as it is pushed through a mixing nozzle. When mixed and injected, the foam expands and hardens, keeping water, acids, greases, gases, insects, and rodents, etc., out of the conduit. The foam has good wetting and adhesion to metals, plastics, and concrete.
FST-250 is used for 50mm or larger conduits. A standard high-ratio caulking tool is required for use.
