Stern Tube Preventive Maintenance

Reduce wear and risk of leakage with ABCON MARINE-STERN TUBE+ in your system. It is an teflon additive which has proven to decrease cost of maintenance on vessels.


STERN TUBE+ is a teflon based paste which produces a teflon layer on the surface of rubber seal rings and on mating metal surfaces. It is extremely protecting against wear on bearings and seals. It reduces the risk of leakage and protects against corrosion as well. Oil analysis from vessels has shown that ABCON+ additives reduce the wear metals by 50% or more.

Blends Perfectly with Stern Tube Oil

STERN TUBE+ blends perfectly with the stern tube oil. The blend produces an excellent lubrication, which due to its teflon content, maintains its’ lubrication effect on the rubber surface as well as on the metal surfaces even at stand still. In case there is saltwater in the lubrication oil STERN TUBE+ provides a substantial safety margin as teflon maintains its lubrication properties even in saltwater.

STERN TUBE+ can be blended with all kinds of mineral and synthetic lubrication oil and can be used together with all types of stern tube seal material.

Bio Based Version

ABCON’s Bio based STERN TUBE B+ version It is based on bio degradable oil. It complies with the 2013 EPA VGP requirements as environmentally acceptable.


Add 1-2% STERN TUBE+ (by volume) to existing system oil.

The product is easy to handle and can be added by own staff.


When dry-docking, it is advisable to use SEAL PROTECT+ as startup lubrication on all rubber seal rings. Past experience has shown us that when SEAL PROTECT+ is used preventively it reduces the risk of leakage.
