Wilden® uses various compounds that consist of natural rubber and man-made additives to increase the compounds’ resistance to specific types of fluids. Rubber diaphragms provide the greatest temperature spans as well as long flex life and are specifically engineered to significantly increase chemical resistance. These diaphragms have exceptional durability from integral nylon fabric mesh. Rubber diaphragms are available in Wilden’s Ultra-Flex™ design as well as the traditional AODD diaphragm shape (pie-shape).
