The CA dust seal has its own product entry in the supplier catalogue, distinct from the Ab and CAI entries.
Provide the groove or component drawing, medium, temperature, movement and existing part reference where available. Request the proposed seal construction and compound information so the selection can be assessed against the actual mating parts and operating duty. Request the current catalogue or drawing for this item, and confirm the offered configuration and supporting documents with the company before specifying an order.
