For those who are unfamiliar with O-ring design, it is recommended to study this introductory section and become familiar with the basic principles of O-ring sealing, their common uses and general limitations. Even those who have designed many O-rings may profit by reviewing the basics from time to time.
This section discusses specific types of O-rings and special applications. Learn the definitions of commonly used terms connected with O-ring seals and gain an understanding of the various common seal types.
Learn more about physical and chemical characteristics in O-ring elastomers and access a brief review of the various elastomers currently available for use in Parker's O-rings and custom elastomeric seals.
It has been said that O-rings are “the finest static seals ever developed.” This section reviews many of the versatile sealing designs that help create leak-free solutions under a wide range of pressures, temperatures and tolerances.
A premature O-ring failure in service is often due to a combination of root causes and not merely a single failure mode. Read this overview on O-ring failure patterns to understand the most common reasons for failures including suggested corrective actions.
