Wärtsilä Stern Tube Seals (Oil)

Most Commercial Stern Tubes are of the oil lubricated type and required a robust and reliable sealing solution.

The technologies behind all Wartsila oil lubricated sealing products are a result of many years of experience and development. Maximising longevity while facilating servicing and maintaining exemplary sealing performance has been our fundamental philosophy. Within the oil lubricated seal product range, there are both face and lipe seal variants to deal with a wide variety of operating profiles including abrasive waters and compliance to anti-pollution requirements.
