ABSTRACT:
The joint between the tank and header of a heat exchanger comprises a channel formed in the header having an inner wall and a bottom, and a rim or foot on the mating edge of the tank. The space between the foot and the channel bottom and inner wall contains an elastomer gasket which is shaped to allow low assembly forces to deform the gasket and fill the space between the tank foot and header pocket, even when high hardness gasket material is used. The gasket includes an enlarged rib, like an O-ring, between the tank foot and header and an integral web portion extending from the rib into the space between the inner wall and the foot to fill and seal that area as well as the area at the bottom of the foot.
