AFT closed-cell sealant provides 10 feet of water-blocking performance in electrical and telecommunication environments. The two-part, closed-cell AFT Sealant is durable and easy to install. AFT has excellent adhesion to a variety of conduits.
AFT seals conduit with quicker installation and higher-performance compared to duct putty or single-part insulating hardware store foams.  The two-part aerosol foam seals any size void and cures without exposure to air.


AFT can be used to seal service entrances, conduit stub-ups, innerducts, inverters and combiners for solar installations and riser poles for the electrical grid. The AFT package is reusable, and the fire retardant seal is self-extinguishing.
AFT is UL recognized and passed UL94 with a Class HBF fire retardant rating.
