Champion Z5157 Valve Set With Gaskets And O Rings

The Champion Z5157 Valve Set with Gaskets and O Rings (R30D) is a complete replacement kit designed for Champion R30D air compressor pumps. It includes the valve assembly plus gaskets and O-rings to seal the valve chamber during operation. Retailers such as Grainger, IAC Service, and Compressor World list Z5157 for the R30D model, with some catalog entries describing it as OEM for the R30D head. The kit is intended for maintenance and overhaul of the R30D head, providing the essential components to service the valve section of the pump. Typical applications include Champion R30D pump assemblies used in residential and light industrial compressors, where replacing worn valve components and seals is part of regular servicing. When ordering, verify compatibility with the R30D model and ensure the kit includes both the valve components and the gaskets and O-rings required for a complete rebuild.
