a first conduit having a first flared end and a first liner protruding from the first flared end;
a second conduit having a second flared end and a second liner protruding from the second flared end;
wherein the first and second liners are joined together so that, with the first and second liners joined together, the first and second flared ends are opposing and spaced apart from one another and portions of the first and second liners are disposed between the first and second flared ends;
an external coupler that is configured to receive the first and second flared ends opposing and spaced apart from one another;
