🔌 Function

The rings seal combustion pressure, transfer piston heat into the liner and scrape excess lubricating oil from the cylinder wall.

Common signs of failure:

• Compression and engine power are low

• Crankcase blow-by and oil consumption increase

• Blue exhaust smoke or oily deposits are present

• Ring lands, liner or rings are worn, broken or carbon-stuck

• Cylinder sealing remains poor after a piston-and-liner overhaul

📦 Condition

• Brand new

• Supplied in original or equivalent packaging
