Abstract
A card seal with an annular arrangement of cards that form the card seal, where the cards each form an L-shape cross section with a wide front face and a narrow side face, where the side face has a constant width from a top end to a location greater than a mid-point, and from this point decreases in width to zero width at the bottom end. The side faces form a blockage against leakage flowing between adjacent cards in a cards seal assembly.
