An HVAC actuator coupleable to an HVAC component is disposed in or at an insulated duct. The HVAC actuator may include a housing and a taping flange. The taping flange may be spaced from the outer surface of the duct and adjacent to an outer surface of an insulated layer of the duct when the HVAC actuator is coupled to the HVAC component, and may be configured to facilitate taping of the HVAC actuator to the outer surface of the insulating layer. It may be shaped to provide a front-facing surface that is suitable for receiving tape to provide a seal between the taping flange and the outer surface of the insulating layer. In some cases, the taping flange may extend outward from the housing around the entire perimeter of the housing. The taping flange may be formed integrally with the housing, or it formed separately and coupled to the housing.
