This Cross Reference tool is to assist the product investigation of users who have technical expertise. No two products are identical, and manufacturing tolerances and specifications often vary between manufacturers. Parker may not be notified by other manufacturers when they make changes to their tolerances and specifications. Accordingly, you as the user, through your own analysis and testing, are solely responsible for making the final selection of the product and assuring that all performance, endurance, maintenance, safety, and warning requirements of the application are met. For further information on comparable products and issues of interchange and intermix, please contact Parker or an authorized Parker Distributor.
