A connector or a connector assembly comprises a fitting, a resilient sealing member, a plurality of protrusions, and a removable stripout layer. The fitting includes a socket. The protrusions extend from the fitting and are connectable to a mating connector. The resilient sealing layer, which is disposed in the socket of the fitting, includes a hollow body having opposite open ends and an internal passage extending between the open ends. The removable stripout layer is movable between a first position in which the stripout layer overlies an end of the resilient sealing member and a second position in which the stripout layer is removed from the end of the resilient sealing member.
