Description

Piston Ring Set R-3802232 (0.50 mm) The R-3802232 0.50 mm Oversize Piston Ring Set (x4) is an OEM-grade replacement designed for diesel engines that require 0.50 mm oversize rings due to cylinder wear, honing, or machining. These piston rings restore sealing efficiency, improve compression, reduce oil consumption, and deliver cleaner, more stable combustion in heavy-duty engine applications. Manufactured using high-strength, heat-resistant alloy materials, this ring set withstands extreme temperatures and high-pressure diesel combustion. Precision-engineered ring profiles ensure proper conformity to the cylinder wall, enhanced ring-to-groove fitment, and smoother piston travel—all contributing to improved fuel economy and reduced blow-by. This set includes four piston ring assemblies , directly replacing OEM 3802233 , ensuring perfect fitment and dependable long-term sealing performance. ✔ Key Features & Technical Advantages OEM-spec R-3802232 0.50 mm oversize piston ring set (x 4) Designed for cylinders machined or honed 0.50 mm oversize Restores compression, reduces blow-by & stabilizes combustion Heat-resistant alloy construction for long service life Reduces oil consumption, exhaust smoke & engine vibration Enhances fuel efficiency and engine responsiveness Precision machining ensures smooth piston movement & reduced friction Direct replacement for OEM 3802233
