Unico has updated the connection system for its flexible supply tubing, reducing the steps and installation time. The new Twist-Fit couplings are attached to Unico flexible round ducts by threading the base of the coupling into the inner core of the tubing. The internal insulation and outer mylar jacket of the supply tubing are then tucked into the rim of the Twist-Fit and the connection is secured with UL-181B foil tape. To make a connection, the installer lines up the tabs to their slots and twists clockwise until a click is heard.
