Champion P03433A Oil Seal

Champion P03433A Oil Seal is an OEM replacement part engineered for Champion R40 and R70 pumps, ensuring an exact fit with the original sealing geometry, the same bore size, and the same mounting interfaces that technicians expect when performing a service. As an oil seal, its primary function is to contain oil within the pump's lubrication system while preventing ingress of dust and moisture, helping to preserve lubrication film integrity and minimize wear on shaft seals and adjacent components during continuous operation. Because it is marketed as an OEM component for Champion's R-series pumps, the P03433A is intended to drop into service without requiring modification to the surrounding hardware, making it suitable for routine maintenance, rebuilds, or field repairs on compatible R40 and R70 models. Techniques and parts lists used by service professionals for Champion air compressor systems often specify the P03433A to maintain original sealing performance, supporting leak-free operation and consistent pump efficiency by restoring the designed containment of lubricants.
