Regardless of all other critical design factors, if the basic composition of the O-ring material is not compatible with its chemical environment, the O-ring will eventually fail.
A primary step in O-ring selection, therefore, is to match your application's chemicals with the O-ring material that offers the best chemical resistance. To do this, refer to the Chemical Compatibility Table in section 6.
A setup charge is a non-recurring fee that is charged to the customer to cover the costs associated with creating a new, custom part or non-standard O-Ring. To help you understand what goes into each of our molded part setup charges, we broke them down by type.
