An example fluid connection system includes: a fitting comprising one or more ears protruding radially outward; a coupling nut comprising at least one helical groove and one or more channels, wherein the one or more channels are configured to allow the one or more ears of the fitting to pass therethrough and reach the at least one helical groove as the coupling nut is slid axially relative to the fitting to mount the coupling nut to the fitting, and wherein the one or more ears are configured to rotationally traverse the at least one helical groove when rotating the coupling nut relative to the fitting, thereby pulling the coupling nut and the fitting toward each other; and an anti-rotation element configured to rotationally couple the fitting to the coupling nut when the coupling nut reaches a predetermined rotational position relative to the fitting.

Fluid connection systems

A threaded coupling for ensuring a complete connection between fluid conduits includes a body portion of a fluid conduit, an axially forward sealing surface, a thread, and an interference member. The interference member is disposed on the body portion and is engageable with a portion of another fluid conduit to apply a load on the interference member when the fluid conduits are threadably connected together. The interference member is configured to prevent a complete sealing engagement between the fluid conduits when the load on the interference member is less than a predefined amount, and is configured to allow the complete sealing engagement between the fluid conduits when the load on the interference member meets or exceeds the predetermined amount.
