Champion ZR15 Piston Ring Set For R10 And R15 Pumps

Champion ZR15 piston ring set for R10 and R15 pumps. This OEM replacement kit from Champion is designed for R-series air compressors and fits pistons with either three or four rings. The ZR15 ring set provides the essential seals between piston and bore, helping restore compression and efficient air delivery in R10 and R15 models. Specifically formulated for Champion R10 and R15 pumps, this kit is intended for rebuilds when ring wear has degraded performance or sealing, enabling continued reliable service. The ZR15 designation identifies the correct ring-set configuration for both 3- and 4-ring piston options used in these pumps, ensuring compatibility with the corresponding piston and cylinder components. As an OEM part, it integrates with the original Champion internals to maintain proper seating, lubrication retention, and longevity of the pump. Ideal for technicians performing routine maintenance or repair on Champion R-series compressors, the ZR15 ring set helps sustain airflow, pressure consistency, and overall pump performance when rings require replacement.
