Sealed Power 2785PN Diesel Cast Piston with Graphite Skirt Coating

The Sealed Power 2785PN is a premium diesel cast piston engineered to meet or exceed original equipment specifications. Cast from Sealed Power's proprietary S2N eutectic aluminum alloy, this piston delivers the strength and thermal stability required for the high-compression demands of diesel engines.

Key Features:

• S2N proprietary alloy construction – engineered eutectic aluminum alloy provides excellent wear resistance and dimensional stability under diesel operating conditions
• Graphite skirt coating – reduces friction and helps prevent scuffing between the piston skirt and cylinder wall during break-in and normal operation
• Bowl-type piston head – designed to optimize combustion chamber geometry for diesel fuel delivery and combustion efficiency
• 3-ring piston design – ring groove widths of 3.02 mm (top), 2.0 mm (second), and 3.0 mm (oil control) for proper ring sealing and oil management
• Premium grade quality – manufactured under ISO and QS certified processes for consistent tolerances and reliable fitment
• Sold individually – available in standard and oversize configurations to accommodate worn or re-bored cylinder bores

The Sealed Power 2785PN cast piston is a trusted choice for engine rebuilders seeking OE-level performance and durability in diesel applications. Its precision machining and proprietary alloy composition ensure a clean installation and long service life.
