Thruster Leakage

Reduce the wear and tear and stop your leaking thrusters with our ABCON MARINE-THRUSTER SL products – no dry-docking, continue operation.

Thruster Leakage

Thruster leakages occur when they are least expected.

By adding one of our ABCON MARINE-THRUSTER Stop Leak additives to the existing system oil, the leakage will be stopped or reduced to an acceptable level in severe cases. We have products that are compatible with all kinds of thrusters lubricated with either mineral oil or biodegradable oil. They can stop leakages in rotating (Azimuth and Azipod) and tunnel thruster units and controllable pitch propeller systems.

All products are easy to handle and can be applied by the staff onboard the vessel.


The high content of Teflon and other complex particles produce a barrier on the damaged surface of the seal ring. Works for leakages as well for water ingress.  As a result, the leakage is significantly reduced or stopped altogether. In case of sea water in the lube oil, the ABCON products will provide a substantial safety margin as Teflon maintains its lubrication properties even in sea water. Furthermore, the products reduce wear and tear.

All our THRUSTER Stop Leak products have hydraulic oil as base oil. This means that it is compatible with gear oil and hydraulic oil, and can, therefore, be used on fixed propellers and CPP propeller systems.
