There are numerous types of O-ring materials available and each offers different features and benefits. Some materials perform well in chemical or high heat applications where others may deteriorate under harsh operating conditions. Even the specific type of oils or chemicals being used in your application determine O-ring material compatibility. Abrasion and tear resistance may also be of importance, especially in dynamic applications or when abrasive substances are involved.
Primary considerations for O-ring material selection include chemical compatibility, application temperature compatibility, sealing pressure, durometer, size and cost. Depending on the application, factors such as electrical properties, dynamic resistance, tear resistance and ozone resistance should also be considered. Taking all these parameters into consideration will help you determine which O-ring material choice is best suited for your application.
