An inlet shut-off bushing (26) for a plastic mold machine includes a threaded connection that seals off the interface between the bushing and the mold. A threaded portion (56) of the bushing is received within the mold so that two surfaces simultaneously bottom out against corresponding surfaces on the mold, thereby sealing off the interface between the bushing and the mold. The bushing body houses heater elements (90) and other components in a manner that isolates them from contaminates or any possible leaking plastic within the assembly.
