Overview
Piston Rings 859989-10 are essential components used in environmental control refrigeration systems, particularly in modulation valves. The rings feature a concentric ring style and a vertical joint style, which contribute to their effective sealing capabilities. With a radial wall thickness that ranges from a minimum of 0.1300 inches to a maximum of 0.1400 inches, these piston rings are built to perform under various conditions. The overall width of the rings falls between 0.0440 inches and 0.0450 inches. Each ring is designed with one hole drilled longitudinally through the axial plane at each end of the joint, with a diameter ranging from 0.062 inches minimum to 0.067 inches maximum, enhancing their functionality and adaptability.
