A quick and reliable way to stop unexpected oil leaks designed with Teflon particles to form a protective layer, ABCON’s preventative solution is available in 12 different additives. All created to stop leaking stern tube seals, thruster seals and hydraulic equipment. Unlike other products, ABCON is added at only 10% maximum of system volume and reacts directly with the seal ring material causing it to swell and form a Teflon seal to prevent further leakage.
Overview of ABCON products
The high content of Teflon and other complex particles produce a barrier on the damaged surface of the sealing ring. As a result, the leakage is significantly reduced or stopped altogether. Should there be water in the lubricating oil, the resulting paste will provide a substantial safety margin as Teflon maintains its lubricating properties even in water. Furthermore, ABCON reduces wear and tear and protects against corrosion.
All our products can be blended with all types of mineral lubrication oil and can be used with all seal ring materials.
Our products are also available in Biodegradable oil-based versions with both saturated and unsaturated ester. They all comply with the 2013 EPA VGP requirements as environmentally acceptable.

Stop leak – Oil leakages and water ingress on stern tubes and thrusters:
Leakages occur when they are least expected. There can be several causes of a leakage, for instance, fishing lines which are pulled into the seals, sand and other impurities damaging the seals when passing through shallow waters, insufficient lubrication of the seals during dry dock, air locks in CPP’s after assembling, oil film pressed out during stand still etc.
Water ingress damages the system as it causes less lubricity and more corrosion
In ABCON, we offer a simple, easy and efficient solution addressing these leakages. By adding one of our Stop Leak products to the existing system oil, a Teflon barrier is created on the damaged seal which reduces the leakage significantly or stops it all together. We provide solutions to both minor and major leakages in all the different kind of seals.

Preventative Maintenance for stern tubes and thrusters
Reduce wear and risk of leakage with our + products in your Sterntube or Thruster system – proven to decrease the maintenance costs on your vessels.
STERN TUBE+ is a Teflon based paste, THRUSTER+ is a hydraulic oil and Teflon based paste.
They create a Teflon layer on the surface of the rubber seal rings and on the mating metal surfaces. It is extremely protecting against wear on bearings and seals. It reduces the risk of leakages and protects against corrosion as well. According to our oil analysis from vessels, ABCON+ additives reduce the metal wear by 50% or more.
When blended with the existing system oil, the blend produces excellent lubrication, which due to its Teflon content, maintains its lubrication effect on the rubber surface as well as on the metal surfaces even during standstill.
In case of longer periods of standstill, the Teflon protects the seals/shafts from running warm at start-up, thereby, reducing the risk of damage
In case there is salty water in the oil, it provides a substantial safety margin as Teflon maintains its lubrication properties even in salty water.
STERN TUBE+ and THRUSTER+ can be blended with all types of mineral and synthetic oils.
