Abstract

The valve element and method of making same are characterized by a valve body having at the neck thereof a small radially outwardly projecting annular crimp bead and a resilient tip molded on the body at the neck. To mold the tip, the body is axially aligned and urged into the mouth of an open ended mold to close the cavity therein with the crimp bead engaging and being crimped by the mold wall to effect a tight annular seal about the body periphery thereby to preclude leakage of fluid material introduced in the closed cavity to form the tip, but without the development of substantial pressures in the mold that might cause excessive wear and damage to the mold.
