Abstract:
A transition apparatus for interconnecting a conduit to a fluid source or reservoir, comprising:an elongated adapter body having a first source end and an opposite second end, the first source end including engagement structure about a portion of the adapter body; a circumferential rib bounding the engagement structure; a pair of annular threaded sections adjacent the rib on the opposite second end, the annular threaded sections being of non-uniform diameter with respect to each other and the diameters of the annular threaded sections being less than the diameter of the rib; the adapter body having an adapter bore extending from the first source end to the second end and tapering radially inwardly from the first source end to a uniform diameter that is then maintained to the second end; a ring member for securement to the annular threaded sections including: a ring bore that is axially aligned with the adapter bore when the ring member is attached to the adapter body; a first interior annular ring threaded portion circumjacent the ring bore for external engagement to the larger-diameter annular threaded sections of the adapter body and terminating at an inner circumferential ledge; at least one pair of projecting members extending from the ring member and coaxial therewith and each projecting member including a lip that extends laterally from the projecting member, an interior surface coextensive with the projecting member, a second interior annular ring threaded portion extending along a portion of the interior surface for engaging the smaller-diameter annular threaded section of the adapter body, and a pair of annular, interior coupling channels with each coupling channel adjacent the projecting members and terminating at an abutment and each coupling channel further defined by an annular guide flange coequal in length with the respective coupling channel.
