For information on troubleshooting for O-rings and seals please see advised guides below. The troubleshooting section includes photos of O-rings and seals damaged from chemical, thermal, or mechanical attack. By understanding the cause of O-ring failure, proper selection of an alternative elastomer or seal design can help improve seal life.
For help in evaluating your sealing performance, DuPont offers assistance in compound selection and seal design for Kalrez® parts. Before an in-depth analysis of O-ring failure can be provided, application data, such as process chemicals, temperatures, etc. must be supplied.
To learn more about elastomer compatibility information visit our web site's Chemical Resistance Guide, request a copy of the Kalrez® Application Guide, or call DuPont at 800-853-5515.
