Elastomer seals are unlike any other materials that design engineers confront. Metal or plastic parts, for instance, are probably failing if visibly distorted. Seals deform into leak paths to function properly. In most applications, o-rings are installed with preset squeeze and stretch as correct design intent.
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.
