150-4789: Top Piston Ring

Description: The piston ring is a split ring that fits into a groove on the outer diameter of a piston in an internal combustion engine. It is the topmost ring that sits closest to the combustion chamber. It is responsible for sealing the combustion chamber from the crankcase, maintaining proper compression within the cylinder, and regulating the flow of oil to the cylinder walls. Attributes: • Designed to withstand high temperatures and pressures while maintaining its shape and seal. • Precision machined to fit the piston groove and cylinder bore. Applications: The piston ring plays a vital role in maintaining proper compression and lubrication. It is extensively used in Cat G3412, CG137-08, XQG400 Engine - Generator Set, G3412, and G3408B, CG137-08, CG137-12 Engine - Industrial.
