Introducing the new FST-250, a multi-use package option for Polywater® FST Foam Duct Sealant. FST is a high-performance, closed-cell foam. The two-part base is mixed in equal parts when pushed through the mixing nozzle, expanding and hardening to seal out water, gases, acids, greases, insects, rodents, and copper thieves from plastic, metal, and concrete conduits. Robust FST seals help protect switchgear, electrical equipment, light fixtures, junction boxes, manholes and more. The FST-250 contains 250 ml (8.5 fluid ounces) of FST Foam in a caulking-gun-style cartridge. The ratchet tool required for dispensing (high-ratio caulking gun) is inexpensive and readily available. Many customers already own one for other purposes: RTV silicone, firestop, etc. We also offer one (catalog #FST-TOOL250). Note that the FST-250 does not replace the popular FST-180 cartridge; it's in addition to it. Now customers have an option--and the mixing nozzles fit both packages. Both cartridge styles are available separately or in kit form with gloves, damming material, positioning rods, etc.
