NPR SWF30026-2 Piston Ring Set

The NPR SWF30026-2 is a precision-engineered piston ring set manufactured by Nippon Piston Ring Co., Ltd., Japan's first piston ring manufacturer established in 1931. This ring set is designed to deliver superior sealing performance, heat dissipation, and oil control under demanding engine operating conditions.

Key Features:

• Manufactured from high-quality materials including cast iron, ductile iron, or high-alloy steel for enhanced durability
• Advanced surface treatments such as chrome plating, ferrox coating, or nitriding for superior wear resistance
• Precision-machined to exacting tolerances for optimal cylinder wall conformity
• Designed to seal combustion gases, control lubricating oil, and dissipate heat effectively
• Reduces oil consumption and prevents gas blow-by and piston scoring

NPR piston rings are trusted by all major Japanese engine manufacturers and are engineered to meet the increasing demands of modern high-performance engines. Each ring set undergoes rigorous testing on actual engine benches to ensure proper fitment and performance.
