Abstract
Abstract An apparatus and method of assembly for a bifurcated tubing connector which is assembled from a relatively small number of integrated parts. The connector includes a tapered, hollow body and cover with standardized fittings. Each fitting is formed of modular components and configurated to receive a coupling which accommodates attachment to a different tubing diameter so that the bifurcated connector of this invention may be used to join two tubes of different diameters into a common fluid stream.
