ABSTRACT:
A connector assembly for permitting sealed passage of tubular lines through portions between separate chambers comprises a first fitting body having a through passage for connection to one of the chambers. The through passage has an outwardly open end with a circumferentially continuous conical mouth. A first rigid disk member with a conical outer surface is received in the conical mouth. Aligned with the first disk member is a second disk member and there are aligned openings formed through both disk members to permit the tubular lines to pass therethrough. Conical chambers are formed about the openings in the first disk member with ferrules positioned therein to closely encircle the tubular lines. A coupling acts to drive the second disk toward the first disk to drive said ferrules into the conical chambers to thereby produce sealing of the ferrules with the lines and to apply force to the first disk to produce sealing between the first disk and the conical mouth.
