8.5-Oz Foam Duct Sealant Kit Single – Foam Sealant for Electrical and Lighting Solutions The 8.5-Oz Foam Duct Sealant Kit Single by American Polywater is a two-part, closed-cell urethane foam sealant designed to provide superior pressure-blocking in demanding environments. It effectively stops water, methane, and other gases to protect electrical systems, making it suitable for use by electrical distributors, lighting solutions providers, wire and cable installers, and switchgear suppliers. The sealant expands and hardens to a semi-permanent, yet removable seal that conforms around complex cable fill configurations to keep out moisture, gases, dust, insects, and rodents. It is compatible with a wide range of cable and conduit materials and is ideal for protecting switchgear, panels, riser poles, combiner boxes, and meters.
