* 2618 alloy for maximum high temperature strength and fatigue resistance.
* "Contour forgings" provide the optimum balance between strength and weight with no grain-interrupting internal milling.
* Proprietary multi-step top ring groove machining process assures optimum control of the groove's size, geometry, flatness, and finish.
* All final turning is performed in one fixturing resulting in complete squareness of rings to the cylinder wall.
* Federal Form-Scan gauging validates ideal skirt indexing to pinhole and skirt-to-skirt polarity.
* Value - added features such as a pressure balance groove included in all series.
* Precise pinhole machining results in an exact compression distance as well as precise lock ring groove spacing, size, and concentricity.
