Abstract: FIG. 2A shows an alignment and sealing arrangement for connecting two non-gender opposed conduit parts (20) and (20'). Seal (22) is captured by two opposed seal protrusions (20C) and (20C') residing on conduit part's end. Bore (18A) of alignment element (18) closely receives opposed alignment protrusions located on conduit parts' end.
