FST™ 8.5-Oz Foam Duct Sealant
Description
FST™ closed-cell sealant provides superior pressure-blocking in the toughest environments. It stops water, methane, and other gases to protect electrical systems. FST Sealant is durable and easy to install.
FST expands and hardens to a semi-permanent, but removable, seal. The foam wets and adheres to metals, plastics, and concrete. It conforms around complex cable fill configurations to keep out moisture, gases, dust, insects, and rodents. FST is a proven solution used to protect switchgear, panels, riser poles, combiner boxes, and meters.
The FST MINI package is designed for 2-inch (50 mm) conduit or smaller.
HYDROSTATIC (PRESSURE) TESTING
FST Sealant is an excellent water block. To test water blocking performance, it is installed into a conduit according to standard procedures, forming a 2-inch (50 mm) plug. Water is added to the system and then pressurized to create a “waterhead”. Seal passes if there is no leakage observed.
