NPR SWT10228-2 Piston Ring Set

The NPR SWT10228-2 is a precision-engineered piston ring set manufactured by Nippon Piston Ring Co., Ltd. (NPR), the world's leading OE piston ring supplier. NPR piston rings are produced to meet or exceed original equipment manufacturer specifications, making them a trusted choice for engine rebuilds and overhaul applications.

Key Features:

• Manufactured by NPR (Nippon Piston Ring), a global OE supplier with over 90 years of piston ring expertise
• Engineered to OEM specifications for precise fit and function
• Advanced surface treatments enhance wear resistance and reduce friction
• Effective combustion gas sealing to restore compression and engine performance
• Precision oil control reduces oil consumption and prevents blow-by
• High-quality materials provide extended service life compared to standard cast iron rings
• Each set includes all rings required for one cylinder: top compression ring, second compression ring, and oil control ring assembly

NPR piston rings serve four critical functions in the combustion chamber: sealing combustion gases, controlling lubricating oil, dissipating heat from the piston, and providing a bearing surface. NPR's rings are tested in cooperation with engine manufacturers to ensure a proper match to engine specifications, and are backed by NPR's limited warranty program.
