Z-Flex Inc. improved on its popular "Z-Vent" vent connector with the debut of the self-sealing Z-Vent III. Canadian Z-Flex product manager Mike Brunt said its new Z-Vent III can reduce a typical 15-minute insulation to 7.5 minutes or less. The Z-Vent III comes with two silicone gaskets already in place. Instead of having to apply silicone cement inside pipe ends before making the connection, the installer only has to slide the two pipes together. "In a snap, it's a permanent seal," Brunt said.
