Seal Moisture, Gases, and Rodents
Out of Conduits and Risers
- Easy Installation 2-minute or shorter application time.

AFT™ closed-cell sealant provides 10 feet of water-blocking in electrical and communication ducts. Because it is a two-part system, humidity is not required for the cure. There is a consistent cure strength throughout the seal. Closed-cell AFT Sealant offers durability as well as ease of use.
AFT shows excellent adhesion to a variety of conduits. AFT seals conduit faster and with better performance than duct putty or one-part insulating foams. The two-part aerosol foam expands to fill any size void. The AFT aerosol spray package comes with multiple actuators, which allow the sealing of multiple ducts.
 Installation of AFT |
 Completed AFT-16 installation |
Seal service entrances, conduit stub-ups, and innerducts with AFT foam. Also protect inverters and combiners in solar panel installations. Another use is sealing the top of riser poles. Use AFT foam wherever you want to storm harden and thus protect the grid.
AFT passes UL94 with a Class HBF fire retardant rating. It is UL recognized and the seal is self-extinguishing.
Installation Instructions:
Shake can for 60 seconds to mix. Lift hinge and insert actuator nozzle into top opening so that the arrow lines up with the nozzle. Invert aerosol can. Insert actuator nozzle all the way into the seal space and fully squeeze the hinge to spray sealant into the conduit.| Catalog # | Package Description | Units/Case |
