Duct coupler devices, systems, and related methods

A duct coupling system comprising:

• two concrete segments, and
• a duct coupling device comprising:
• a body having opposing end portions;
• and
• at least two sealing members;
• a first coupler transition configured to receive a first end of the duct coupling device;
• and
• a second coupler transition configured to receive a second end of the duct coupling device;
• wherein the sealing members are each configured to seal an annular space disposed between a first surface of the duct coupling device and a surface of the first and second coupler transitions,
• wherein the coupling device comprises at least one or more apertures on each of the opposing end portions for passage of a fluid medium between the coupling device and the first and second coupler transitions, and
• wherein the coupling device is configured to join the concrete segments such that there is a gap between faces of the concrete segments.

A method for coupling ducts, the method comprising:

• providing a first coupler transition on a first duct;
• providing a second coupler transition on a second duct;
• and
• providing a duct coupling device between the first and second coupler transitions,
• wherein the duct coupling device comprises:
• a sealing member configured to seal an annular space between a surface of the duct coupling device and surfaces of each coupler transition;
• and
• one or more apertures on opposing end portions.
