The Parker O-Ring eHandbook is a condensed online version of the printed Parker O-Ring Handbook ORD 5700. On these pages, you will find information about the properties of basic sealing elastomers, as well as examples of typical o-ring applications, fundamentals of static and dynamic seal design and o-ring failure modes. It also provides an overview of international sizes and standards, and compatibility data for fluids, gases and solids.

O-Ring Basics

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.
