🔌 Function

Seals the heat-exchanger end covers around the tube stack, preventing raw-water and coolant leakage while directing water correctly through the exchanger core.

Common signs replacement is required:

• Raw-water or coolant leakage from an exchanger end cover

• Salt deposits, staining or corrosion around the end caps

• Coolant loss or rising engine temperature

• Damaged gaskets after heat-exchanger removal

• Poor sealing following core cleaning or descaling
