A connector (20) is provided for mounting on an anesthetic vaporizer (22) to connect the inlet of the vaporizer (22) with a discharge port (42) of a container (24) of liquid anesthetic (26). The connector (20) includes a first coupling (47) attachable to the vaporizer (22) and defining a first passage (61) communicating at one end with the vaporizer inlet. A second coupling (49) is attachable to the container (24) and defines a second passage (68) communicating at one end with the container discharge port (42). A third passage (70) defined by one of the couplings (47, 49) and communicates with one of the first and second passages (61, 68). A combination valve and mounting structure is cooperatively defined by the couplings (47, 49) to accommodate pivoting of the second coupling (49) to a closed position occluding the first and second passages (61, 68), to a raised fill position establishing communication between the first and second passages (61, 68), and to a lowered drain position in which the first and second passages (61, 68) communicate through the third passage (70).
