Devices and methods of manufacturing couplers for the transition of different conduit systems

A system for connecting a first conduit to a second conduit comprising:

• a coupling device for coupling the first conduit and the second conduit comprising:
• a first member comprising:
• a body defining a channel having a first opening and a second opening, and
• one or more threads located on an inner surface of the channel at the second opening,
• wherein the first member is configured to receive the first conduit at the first opening and receive the second conduit at the second opening, and the one or more threads engages one or more threads of the second conduit;
• and
• a second member circumferentially disposed around a periphery of the first member at the second opening and axially extending from the first member,
• wherein the second member comprises an inner diameter configured based on an outer diameter of the second conduit to enable a portion of the second member extending from the first member to form a seal around the second conduit when the second conduit fully engages the first member;
• wherein the channel extends through the first member and the second member such that a first end of the coupling device is in fluid communication with a second end of the coupling device;
• wherein the coupling device is formed by over molding the second member onto the periphery of the first member.

A method of manufacturing a coupling device comprising:

• obtaining a first member having a first melting temperature, wherein the first member comprises a body defining a channel having a first opening and a second opening, and one or more threads located on an inner surface of the channel at the second opening;
• obtaining a flexible polymer material having a second melting temperature;
• and
• over molding the flexible polymer material onto the first member at a temperature less than the first melting temperature and above the second melting temperature to form a second member;
• wherein a portion of the second member axially extending from the first member further defines the channel such that a first end of the coupling device is in fluid communication with a second end of the coupling device.
