Click-seal torque limiting connector designs

A method of connecting fluid supply lines to a fluid connector assembly, comprising:

• (a) providing a first fluid supply line with internal threads;
• (b) fastening an externally threaded connector assembly to the internal threads of the first supply line, wherein the externally threaded connector assembly comprises:
• (i) an outer fastener comprising a top surface, a bottom surface, and a plurality of radially extending members on the top surface;
• (ii) a fastener insert comprising a top surface, a bottom surface, external threads, and a plurality of radially extending projections dimensioned to be received by the radially extending members when the fastener insert is assembled with the outer fastener;
• (c) rotating the outer fastener to rotably tighten the externally threads of the fastener insert to the internal threads of the first fluid supply line until a predetermined torque is reached;
• wherein if the outer fastener continues to be rotated after the predetermined torque is reached, the radially extending projections of the fastener insert slip over the radially extending projections of the outer fastener.

A fluid connector assembly, comprising:

• a first and a second outer fastener, each outer fastener comprising a front surface, a back surface, and a plurality of inwardly extending axial portions separated by axially extending slots;
• and
• a first and a second fastener insert, each fastener insert comprising a front surface, a back surface, threading, and a plurality of outwardly extending axial projections configured to be received by the axially extending slots when an associated fastener insert is assembled with an associated outer fastener;
• wherein the first fastener insert is received by the first outer fastener and the second fastener insert is received by the second outer fastener;
• and
• wherein the first and second fastener inserts interlock after being received by an associated outer fastener.

A method of connecting fluid supply lines to a fluid connector assembly, comprising:

• (a) providing a first fluid supply line with threading;
• (b) fastening the threading of the first fluid supply line to a threaded connector assembly, wherein the threaded connector assembly comprises:
• (i) a first and a second outer fastener, each outer fastener comprising a front opening, a back opening, and a plurality of inwardly extending axial portions separated by axially extending slots;
• and
• (ii) a first and a second fastener insert, each fastener insert comprising threading, a front opening, a back opening, and a plurality of outwardly extending axial portions configured to be received by the axially extending slots when an associated fastener insert is assembled with an associated outer fastener;
• wherein the first outer fastener is assembled with the first fastener insert and the second outer fastener is assembled with the second fastener insert;
• and
• wherein the first and second fastener inserts interlock with each other at a corresponding back opening;
• (c) rotating the first outer fastener to rotably tighten the threading of the first fastener insert to the threading of the first fluid supply line until a predetermined torque is reached;
• and
• wherein if the first outer fastener continues to be rotated after the predetermined torque is reached, the outwardly extending projections of the first fastener insert slip over the inwardly extending axial portions of the first outer fastener to prevent the predetermined torque from being exceeded.
