Selecting an O-Ring material for a specific application depends on many important criteria including:
Service Conditions (media to be sealed, temperature range, pressure/vacuum range, dynamic motion)
Design Attributes (component geometry, desired service life, installation considerations, tolerances)

This guide is intended for general reference use only.
The materials and compound numbers listed are the most commonly used.
There are numerous compound variations designed for specific applications.
For demanding applications, please provide all the details to our application engineers for a recommendation.
