R. E. Purvis & Associates, Inc. and Parker Seal provide rubber bonded to metal solutions. This is a superior solution in many instances where a current rubber metal combination arrangement will not work. The flexibility of this option makes it a valuable asset when considering what design to use in your application.
A major valve manufacturer was experiencing issues when using a rubber seal that was pressed onto a metal substrate. The seal would come loose during assembly which led to extended assembly time. This customer found it difficult to catch this issue during end of line checks, which resulted in field failures, warranty claims, and unhappy customers.
R. E. Purvis & Associates, Inc. and Parker ESD Division proposed a solution of molding the rubber seal onto the metal substrate. While this proposal increased piece part price, it was more than offset by reduced assembly time, elimination of field failures, and greater customer satisfaction.
