ABSTRACT:
A shrouded tubing interface for quickly connecting, disconnecting and avoiding contamination of first and second fluid flow lines comprising male and female connectors, each of which are connected to a respective one of the fluid flow lines. The male connector includes a first tubular portion defining a distal tip and a tapered outer surface, while the female connector includes a second tubular portion having a distal tip and a tapered inner surface. The tapered surfaces of the first and second tubular portions are mutually tapered such that the first and second tubular portions are axially interfittable. The male and female connectors further include first and second tubular skirt portions, respectively, associated with and extending about the respective tubular portions which are adapted to prevent contact to respective ones of the distal ends, and are further positioned to radially and axially overlap when the tubular portions are brought into interfitting engagement at the tapering surfaces.
