O Ring Material Selection guide can be a difficult task. Here we have described the various materials and its properties based on certain key factors like temperature, pressure.

Based on the properties the materials possess they are used for varied applications ranging from Space Exploration to Industries to Dams.

At Ismat , we work with more than 20+ o ring material types
