Piston Rings are made from high quality Grey Iron Castings (Individual Casting) with an ideal chemical composition for prolonged working life. Fine grain castings provide high tension even at elevated temperature of high speed engines.

Hard chromium is Electro- deposited on the periphery of rings to achieve high abrasive wear. Duaflex oil control rings are chromium plated on their fully radiused edges to provide wear resistant wiping surface free of sharp corners or cutting edges which may cause bore wear. Each iron ring is Parco lubrized and it produces a lightly etched surface to provide oil retaining phosphate coating. This type of surface minimises scuffing, assists running -in and affords some protection during stotage. Each ring is properly inspected by modern techniques to ensure material and dimensional accuracy for the best results of high compression and less oil usage.
