Depending on the profile and the required characteristics of its components, rod and buffer seals can consist of one or several materials.

Common materials used for rod seal anti-extrusion rings are polyamide (PA), polyacetal (POM) or PTFE. The materials used for a specific profile are provided in the Profile overview and in the relevant profile sections below.
