Every day we are partners in seal design and troubleshooting with engineers in industries as diverse as automotive, computer and medical devices. This experience has taught us that most successful seal designs are the result of what we call “Seal Thinking™” the careful application of sealing concepts that are basic, but not obvious or intuitive.

The Apple Rubber Seal Design Guide makes “Seal Thinking™” even more accessible. The “Rules of Thumb” feature is the product of hundreds of conversations with engineers about what must be emphasized to achieve a successful design. We have been very fortunate in the many opportunities we have had to work with dedicated and gifted engineers. In a very real sense, they are contributors as well.
