FST™ Foam Sealant Kit, Single Kit

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.
