1. A flat flexible cable (FFC) seal, comprising:
an elastomeric body defining a generally hollow interior space and including:
a first seal portion surrounding the interior space and defining an outwardly extending first sealing rib, and a cavity formed into the first seal portion in an axial direction and sized to receive a portion of a connector component; and
a second seal portion surrounding the interior space and defining an outwardly extending second sealing rib, the second seal portion extending in the axial direction of the body from an end of the first seal portion, the second seal portion being foldable into the interior space of and under the first seal portion such that that second sealing rib extends inwardly into the interior space.

a connector component having a cable opening sized to receive an FFC; and
a cable seal arranged within the connector component and defining an interior space corresponding to the cable opening, the cable seal defining:
a first seal portion surrounding the cable opening and comprising an outwardly extending first sealing rib; and
a second seal portion extending from an end of the first seal portion and folded into the interior space and under the first seal portion, the second seal portion defining an inwardly extending second sealing rib adapted to engage with the FFC inserted into the cable opening of the component.
 
17. A method of forming a seal for a flat flexible cable (FFC), comprising:
forming a first seal portion surrounding an interior space, the first seal portion comprising an outwardly extending first sealing rib about its periphery;
forming a second seal portion on an end of the first seal portion, the second seal portion comprising an outwardly extending second sealing rib about its periphery; and
folding the second seal portion into the interior space and under the first seal portion such that the second sealing rib extends inwardly into the interior space.
