Description
Centering ring with fine filter and Perbunan O-ring is a stainless-steel vacuum flange accessory designed for DN 100 ISO-K connections in laboratory and process vacuum systems. The integrated fine filter supports cleaner gas paths by helping retain particulates at the joint, while the Perbunan O-ring provides the sealing interface between mating flanges. Built as a compact centering element, the ring aligns the flange faces and maintains a defined sealing geometry during assembly of ISO-K components. This configuration is intended for routine use on vacuum lines, pumps, and apparatus where a filtered centering ring is preferred over a plain ring. Supplied as a single piece from manufacturer WELCH, it fits standard DN 100 ISO-K hardware and is suitable as an original-equipment-style spare or replacement part in analytical, research, and industrial laboratory setups. The stainless-steel body offers mechanical stability at the flange interface, and the Perbunan elastomer seal is selected for typical laboratory vacuum sealing duties. Use the ring wherever DN 100 ISO-K centering with an integrated fine filter is specified for system maintenance or new builds.
