8.5-Oz Foam Duct Sealant Cartridge
FST closed-cell duct sealant provides superior pressure-blocking power in the toughest environments. It stops methane and other gases to keep electrical systems intact. FST Duct Sealant is stronger, more chemically resistant, and cures 50 times faster than open-cell aerosol foams. The FST seal has excellent adhesion to PVC, rigid steel, EMT, IMC, fiberglass and polyethylene conduits. FST is a proven solution that has been used for years to protect switchgear, panels, riser poles, combiner boxes, meters, and all types of electrical and telecommunication apparatus. It creates a semi-permanent seal and is reenterable. A properly constructed FST seal is pictured on the left, installed in a transparent tube to show the structure of the seal inside the duct. Damming strips are wrapped around the cables to create a void into which the two-part liquid FST mixture is injected. The damming strips help contain the FST mixture at the mouth of the duct while it expands and hardens into a strong, resilient seal. The damming strips also separate cables so that the expanding foam can flow around them to prevent leakage between them. Inject the sealant with a high-ratio caulking gun for immediate protection of high-value network assets.
