Abstract

A cable system component includes a nut having a seal-grasping surface portion and a seal having an elastically deformable tubular body attached to the nut. The body has a posterior sealing surface that cooperatively engages the seal-grasping surface portion of the nut and a forward sealing surface configured to cooperatively engage an interface port. The seal includes a nonconductive elastomer overlying a conductive elastomer in a radial dimension of the seal. The conductive elastomer is configured to make an electrical ground connection with the interface port before a center conductor of the coaxial cable makes an electrical connection with an internal contact of the interface port when the nut is coupled with the interface port.
