Overview:Insulated reducing couping for steel to cast/ductile.
Style 39-62 is a combination insulating and reducing coupling. It is most widely used where cast-iron and steel pipe are joined in a system. It eliminates corrosion problems created by joining dissimilar metal structures. The insulating gasket is typically furnished on the larger end for cast iron. A plastic boot insulating sleeve prevents pipe-end contact with the middle ring and a slider spacer separates the pipe ends.
