Vent Seals and Flaps

Vent seals and flaps – Air vents that are seen from the automobile cabin are typically fed cold and hot air via blow molded air ductwork. The blow molded ducts never have a perfect air seal with the rear side of the actual air vent. To prevent air loss behind the vent, Derby can provide die cut low air permeable foam gaskets that are commonly used to insure a good seal. There are also vents that allow air to escape from the cabin. These vents are intended to be an air escape only, and cannot allow air in the reverse direction. Derby produces dozens of custom design shaped rubber flaps that are mounted to the vent and have a natural hinge that allows the flap to open in the exit direction only.
