A coaxial cable connector having a connector body attached to a post, the post having a first end, a second end, and a flange proximate the first end, wherein the post is configured to receive a center conductor surrounded by a dielectric of a coaxial cable, a port coupling element attached to the post, and a seal member disposed proximate the dielectric to create a seal around the dielectric to prevent entry of environmental elements is provided. Additionally, a connector having a post with an internally tapered surface proximate a first end, the internally tapered surface tapering radially inward toward the first end to compress the dielectric to form a seal around the dielectric is provided. Furthermore, an associated method is also provided.
