O-Ring Basics

The Parker O-Ring eHandbook is a condensed online version of the printed Parker O-Ring Handbook ORD 5700. 

For those who are unfamiliar with O-ring design, it is recommended to first study this introductory section, becoming familiar with the basic principles of O-ring sealing, their common uses and general limitations.

Those who are already familiar with O-ring seal design may simply refer to the appropriate design tables for the information needed. Even those who have designed many O-rings may profit by reviewing the basics from time to time.
