Description: Consisting of lock-and-release tabs, these couplings are attached to lengths of sound attenuator or standard supply tubing 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. Matching couplings are attached to the desired plenum take-offs, terminating outlets, or additional lengths of supply tubing. To make a connection, the installer lines up the tabs to their corresponding slots and twists clockwise until a click is heard. At least one connector must have a gasket to prevent leakage. The connectors are available for 2-inch inner diameter take-offs, supply tubing, and outlets. A video demonstration of the connection can be viewed online.
