Engine piston rings are critical components that seal the combustion chamber, regulate oil consumption, and transfer heat in marine engines. Marine engine spares include these rings to ensure optimal engine performance and longevity. They are designed to withstand high temperatures and pressures in harsh marine environments.

Size: 50mm to 500mm diameter (varies by engine model)

Grade: API, ASTM, or OEM-specific standards (e.g., ISO 6621-3)

Viscosity: N/A (piston rings do not have viscosity; lubricating oil viscosity typically SAE 30-50)

Buoyancy: N/A (not applicable for piston rings)

Material: Cast iron, ductile iron, steel, or chrome-plated alloys

Compression Ring Thickness: 1.5mm to 3mm

Oil Control Ring Width: 2mm to 5mm

Hardness: 180-300 HB (varies by material)

Coating: Chrome, molybdenum, or phosphate for wear resistance

Operating Temperature: Up to 300°C (572°F)

Pressure Resistance: 150-300 bar (depends on engine type)

Yes, Engine Piston Rings and Marine Engine Spares typically comply with maritime standards such as ISO 9001, ISO 14001, and classification society standards like ABS, DNV, or Lloyd's Register.
