Abstract: A connector interface includes: a first connector having an outer body with a first bearing surface facing in a first axial direction; a second connector having an outer body with a second bearing surface facing in a second axial direction opposite the first axial direction; a resilient sealing element disposed between the first and second bearing surfaces; and a coupling nut associated with the first connector and configured to engage a feature on the second connector. Rotation of the coupling nut relative to the first and second connectors draws the first and second bearing surfaces toward each other to compress the sealing element such that the sealing element bulges radially outwardly to engage an inner surface of the coupling nut.
