A cover (100) for a fiber optic cable connection includes a cap portion (200) having a first housing portion (202) having a first housing wall, a second housing portion (204) having a second housing wall, and a coupler portion (250) that couples the first housing portion and the second housing portion in a closed position. The first housing wall and the second housing wall define a housing opening. A sealing assembly (290) is received within the housing opening and has an inner surface (310) and an outer surface (312). The inner surface defines a sealing opening that receives a fiber optic cable. The outer surface contacts at least one of the first housing wall or the second housing wall when the sealing assembly is received within the housing opening. The sealing assembly creates an additional seal when the first housing wall and the second housing wall compress the sealing assembly onto a union portion.
