How This Guide Works

Apple Rubber's version 2.0 for the web is organized into 12 sections. You can start wherever you like, but we recommend you at least go over the Rules of Thumb.

In this guide you will find information on basic concepts of O-ring design; seal types and gland design, critical operating environmental factors, a material selection guide, troubleshooting, ordering procedures, O-ring size charts, and much more. Our goal is to offer you the most comprehensive guide in the seal industry today.
