NPR SWF30027-3 Piston Ring Set - Ford Engine

The NPR SWF30027-3 is a precision-engineered piston ring set manufactured by NPR of America (Nippon Piston Ring), one of the world's leading OEM and aftermarket piston ring suppliers. Designed for Ford engine applications, this ring set delivers the sealing performance, oil control, and durability required for reliable engine operation.

Key Features:

• OEM-Grade Quality: Manufactured to meet or exceed original equipment specifications, ensuring a proper fit and reliable seal
• Combustion Gas Sealing: Precision ring geometry maintains a tight seal against the cylinder wall to prevent blow-by and maintain compression
• Oil Film Control: Engineered to maintain the correct lubricating oil film on cylinder walls, preventing excessive oil consumption and reducing the risk of scuffing
• Heat Dissipation: Efficiently transfers heat from the piston head to the cylinder wall, protecting pistons from thermal damage
• Advanced Surface Treatments: Rings undergo surface treatments such as nitriding or PVD coating to enhance wear resistance and extend service life
• Steel Construction: High-strength steel ring design offers superior fatigue life, reduced radial wall thickness, and improved conformability to cylinder bore geometry compared to traditional cast iron
• JIS Standard Manufacturing: Produced in accordance with JIS (Japanese Industrial Standard) B8032-6-1998 for consistent quality and dimensional accuracy

NPR of America has been supplying piston rings to OEM manufacturers and the aftermarket since 1973. The SWF30027-3 ring set is engineered to restore engine compression, reduce oil consumption, and support long-term engine reliability. Always use a piston ring installation tool during installation and ensure cylinder bores are properly honed before fitment.
