Description

The Cummins Piston Ring Set 3802232 (0.50 mm oversize) is a precision-engineered replacement designed for rebuilt diesel engines that have undergone cylinder boring. This ring set directly replaces OE Cummins part number 3802233 , delivering OEM-level fitment, sealing performance, and long service life. Designed for Cummins diesel engines , this 0.50 mm oversize piston ring set is used when standard rings can no longer maintain proper compression due to cylinder wear. It restores combustion efficiency, minimizes blow-by, and provides consistent oil control under heavy-duty operating conditions. Each ring is manufactured from high-strength, wear-resistant materials and precision-machined to ensure accurate seating against freshly bored cylinder walls. The optimized ring profile supports stable compression, reduced oil consumption, and extended cylinder life, even in high-load commercial and industrial diesel applications.
