Claim:
1. A fiber optic connector comprising: a main outer housing having a distal end and a proximal end, the main outer housing also including a length that extends along a longitudinal axis of the fiber optic connector between the proximal and distal ends of the main outer housing; an inner housing that mounts within the main outer housing, the inner housing being secured to the main outer housing by a first snap-fit connection, the inner housing having a length that extends along the longitudinal axis of the fiber optic connector between proximal and distal ends of the inner housing; a plug interface housing secured at the distal end of the inner housing by a second snap-fit connection; a ferrule assembly mounted at least partially within the plug interface housing, the ferrule assembly having a ferrule having a length that extends along the longitudinal axis between proximal and distal ends of the ferrule, the distal end of the ferrule including an interface end face, the ferrule assembly also including a hub mounted at the proximal end of the ferrule; a spring for biasing the ferrule assembly in a distal direction; a resilient cable seal that mounts within the main outer housing, the resilient cable seal having a main body including a length that extends along the longitudinal axis between proximal and distal ends of the resilient cable seal, the resilient cable seal defining a cable sealing passage that extends through the resilient cable seal from the proximal end of the resilient cable seal to the distal end of the resilient cable seal, the resilient cable seal including a plurality of cable sealing ribs that project inwardly into the cable sealing passage from the main body of the resilient cable seal, each of the cable sealing ribs surrounding the longitudinal axis, the cable sealing ribs being spaced-apart from one another along the longitudinal axis and being separated by inner grooves that extend around the longitudinal axis, the resilient cable seal also including a housing sealing portion positioned adjacent the distal end of the resilient cable seal, the housing sealing portion including a plurality of housing sealing ribs that project outwardly from the main body of the resilient cable seal, the housing sealing ribs being spaced-apart from one another along the longitudinal axis and being separated by outer grooves that extend around the longitudinal axis, the resilient cable seal also including an end cap engagement portion positioned adjacent to the proximal end of the resilient cable seal; an end cap mounted at the proximal end of the main outer housing, the end cap being secured to the main outer housing by a third snap-fit connection, the end cap fitting over the end cap engagement portion of the resilient cable seal and being configured to compress the resilient cable seal inwardly toward the longitudinal axis; and a coupling nut that mounts over the main outer housing.
