A bushing used in an injection molding machine and positioned between the nozzle and the sprue thereof includes an adaptor body having a longitudinal axis, a first end and a second end. A first bore extends in the adaptor body parallel to the longitudinal axis from the second end to the first end for accommodating a flow of relatively viscous fluid such as a molten thermoplastic. A bridge extends transversely across the first bore between opposing walls of the bore adjacent the adaptor body first end. Fluid flow is allowed through the first bore around the bridge. A second bore extends from a surface of the adaptor body to a surface of the bridge for accommodating a flow of a relatively non-viscous fluid such as gas. The second bore terminates on the bridge surface so as to be substantially coaxial with the first bore.
