All O-ring seal applications are categorized in terms of relative motion. In situations involving little or no motion relative to the seal, the O-ring application is STATIC. In situations involving reciprocating, rotating, or oscillating motion relative to the seal, the O-ring application is DYNAMIC.
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.
