An HVAC duct sealing system has an air duct wall, a sealing surface, such as an HVAC case, against which the air duct wall is biased, and a seal member interposed between the duct wall and the sealing surface. The seal member is interposed between the air duct wall and the sealing surface and is molded directly onto the air duct wall using a two-shot or double shot method of forming. The seal can be rubber or any flexible, pliable material capable of creating a seal with a surface. The seal has a seal base that is attached to and surrounds an end part and two sides of the air duct wall. The seal has a flexible tip portion extending from the seal base that is biased against and bends against the sealing surface in accordance with an amount of pressing force to create a seal. The flexible tip bends between 0 and 100 degrees from its pre-installation position.
An air duct seal comprising:
An air duct seal comprising:
A vehicular HVAC air duct sealing apparatus, the sealing apparatus comprising a double-shot molded flexible seal upon an end of an air duct wall, the flexible seal including a laterally extending end face, the laterally extending end face being adapted to contact an adjacent sealing face to deflect the flexible seal in one of two directions upon said contact, the flexible seal protruding from the end of the air duct wall and bending in accordance with an amount of force applied to the flexible seal by a sealing surface, wherein the protruding flexible seal is located apart from the air duct wall.
