NPR SWF30016-0 Piston Ring Set

The NPR SWF30016-0 is a precision-engineered piston ring set manufactured by Nippon Piston Ring Co., Ltd. (NPR of America). NPR piston rings are designed to meet the demanding requirements of modern internal combustion engines, providing superior sealing, oil control, and heat dissipation under extreme operating conditions.

Key Features:

• Engineered to seal combustion gases and prevent blow-by
• Controls lubricating oil consumption for optimal engine performance
• Efficiently dissipates heat from piston to cylinder wall
• Manufactured to meet JIS (Japanese Industrial Standard) B8032-6-1998 specifications
• Features advanced surface treatments for enhanced wear resistance and durability
• Precision-ground for proper ring tension and sealing properties

NPR piston rings utilize high-quality materials including cast iron, ductile iron, and steel construction, with specialized coatings such as chrome plating, nitriding, or PVD treatment to ensure long service life. Each ring set is engineered to maintain complete contact around the cylinder wall circumference while providing proper clearance between piston and cylinder, preventing scoring and excessive wear.
