A needleless connector includes a two-part housing with an inlet, an outlet, and a conical chamber therebetween that compressibly receives a resilient conical valve head. The conical valve head includes a stationary base, and a tip portion movably extending into the inlet. The conical valve head is concentrically positioned against the valve seat to form a seal. When the male fitting of a syringe, or some other device, is inserted into the inlet, it pushes a tip portion of the resilient valve head inwardly, so that the valve head is deformed away from the valve seat to break the seal. The needleless connector employs only three separate parts-the two-part housing, and the valve head-so that it is very economical to manufacture.
