Beschreibung
Zusammenfassung:	A method for sealing cable conduits utilizes a spray nozzle which includes at least two compartments for holding chemical compositions in a spaced apart while a piston is utilized for simultaneously forcing the chemical compositions out of the compartments and into an elongate nozzle for commingling the chemical compositions and introducing the commingled compositions into the end of a cable conduit in a direction generally perpendicular to an axis of the elongate nozzle to cause complete wetting of the conduit inner surface with the commingled composition before foaming thereof.
