A seal device is provided for sealing a cylindrical component upon axial insertion of the cylindrical component, with the seal device including an annular flange portion defining a first opening having a first diameter, and a skirt portion integral with the annular flange portion and extending axially and radially inward from the flange portion. The skirt portion includes a plurality of first sectors extending axially inward from the flange portion to an axially inner edge of the skirt portion, each having an inner undulation defining a second opening having a second diameter smaller than the first diameter. The plurality of first sectors are circumferentially spaced apart by a plurality of second sectors extending axially outward from the flange portion to the axially inner edge of the skirt portion, each having an outer undulation defining a third opening having a third diameter smaller than the first diameter.
