A seal to couple a cable to a fuse box, the seal comprising:

• a plastic body comprising a receiving cavity disposed along an inner surface;
• and
• a rubber insert comprising:
• an outside structure to join with the inner surface;
• an inside structure to surround the cable;
• a fitting rib disposed along an outside surface of the outside structure, the fitting rib to occupy the receiving cavity;
• a rib disposed circumferentially on an insertion side of the inside structure, the rib to overlap with the cable;
• a ring disposed circumferentially around the outside structure and coupled to the fitting rib;
• one or more ring ribs extending from the ring toward the fuse box, wherein the one or more ring ribs fit tightly against a surface of the fuse box;
• and
• a gripper section disposed circumferentially on a terminal side of the inside structure, the gripper section to overlap with the cable, wherein the gripper section comprises first, second, and third grippers, the rib, the first gripper, the second gripper, and the third gripper to form a gradient that provides IP69 protection of the fuse box;
• wherein the inside structure of the rubber insert moves in response to movement of the cable while the outside structure does not move.
