Seal Material Selection

Seals are used under many different operating conditions and so material selection for mechanical seals can be a challenge. Additionally, because seals can be manufactured from, or contain, such a wide variety of materials the final design decision on the seal material can be really quite a complex one.  

With seal materials available from metals, ceramics, elastomers, non-elastomer gaskets, and carbons, the designer or material selector must be knowledgeable about many different materials with significantly different properties.

The standard ISO 3601 has a number of provisions covering O-Rings and the suitability of elastomeric products for industrial applications.
