Nut for tube connector assembly

A nut for a connector assembly for a tube comprising:

• an annular nut body oriented down a central axis, the annular nut body having a cross-section taken along the central axis comprising:
• an axially projecting portion comprising exterior threadings and an end portion;
• and
• a radially projecting portion disposed axially adjacent to the axially projecting portion, wherein the radially projecting portion comprises a first flange projecting radially inward, wherein at least one of the first flange or the end portion is adapted to seal against a neighboring component, and wherein the annular nut body further comprises a circumferential split.

A connector assembly for a tube comprising:

• a body provided with a cavity extending in an axial direction,
• a ring adapted to be mounted at the periphery of a useful portion of the tube, the ring having at one end a support surface adapted to receive a curved end portion of the tube, and
• a nut adapted to be screwed onto the body so as to engage the ring to press the curved end portion of the tube against a receiving surface in the axial direction, and an annular receiving part forming the receiving surface and removably mounted on the body, wherein the nut comprises:
• an annular nut body and oriented down a central axis, the annular nut body having a cross-section taken along the central axis comprising:
• an axially projecting portion comprising external threadings and an end portion;
• and
• a radially projecting portion disposed axially adjacent to the axially projecting portion, wherein at least one of 1) the radially projecting portion comprises a
• first flange projecting radially inward, wherein at least one of the first flange or the end portion is adapted to seal against receiving part, or 2) wherein the annular nut body comprises a polymer and further comprises a circumferential split.
