A sealing cup is a precision-formed cup-shaped seal used within hydraulic, fuel, or fluid-handling circuits to maintain pressure and prevent fluid from bypassing moving components or escaping the system. In generator applications, a failed or worn sealing cup can result in fluid leaks, pressure loss, and contamination of surrounding components — any of which can lead to generator malfunction or unplanned service. Replacing a worn sealing cup with the correct OEM part restores the system to its original pressure-holding capability and protects downstream components from accelerated wear.
