Fuseal Squared® Double Containment Corrosive Waste


Federal, state and local regulations have been created to protect our environment from industrial pollution. Protection of the soil and the groundwater table are of primary concern. The Fuseal Squared® system, with a modular design, is a reliable and cost-effective solution for conveyance of industrial and laboratory waste products. Excellent chemical and physical properties make the system ideal for handling corrosive waste solutions present in laboratory and industrial DWV applications where double containment is required.

Fuseal Squared® in Polypropylene or PVDF combines the advantages of corrosion-resistant and flame retardant drainage piping with the added security of double-containment.
