NPR SWF30019-0 Piston Ring Set

The NPR SWF30019-0 is a precision-engineered piston ring set manufactured by NPR of America (Nippon Piston Ring). NPR piston rings are designed to deliver reliable sealing performance in demanding engine environments, serving critical functions including combustion gas sealing, oil control, heat dissipation, and prevention of wear and seizure.

Key Features:

• Engineered to meet JIS (Japanese Industrial Standard) B8032-6-1998 specifications
• Advanced material construction using cast iron, ductile iron, or steel depending on application requirements
• Enhanced wear resistance through surface treatments including chrome plating, nitriding, and PVD coating
• Precision-machined to maintain proper clearances and complete cylinder wall contact
• Designed to prevent gas blow-by and reduce oil consumption
• Meets the demands of modern high-compression, high-temperature engines

NPR piston rings are manufactured with decades of engineering expertise and are tested to ensure optimal performance and durability. The proper installation of these rings is essential for maintaining engine compression, controlling lubrication, and maximizing engine life.
