Abcon B Series Lubricating Paste

Sub-Sea Seal Repair & Conditioning Paste


Abcon Lubricating Paste’s have been developed specifically for leaking sub‐sea sealing systems. They can be used as lubricating paste on its own or, if added at a rate of up to 8% of leaking systems oil volume, as an additive enhancing wear protecting properties as well a sealing ability in both inner and outer seals.

Abcon B Series are a very complex Bio Oil based paste’s containing seal surface improving additives while maintaining compliance with the EPA’s VGP 2013 regulations. Abcon B Series are excellent lubricating pastes due the active components that reduce the friction and hence the wear between the bearing/seals and a propeller shaft, CPP or bow thruster. It builds a surface layer on the seal for supporting damaged and worn seals both in motion and at rest.

Furthermore. In addition. Abcon B Series contains a very high amount of Teflon, which due to low friction will embed the wear surfaces during operation, repairing minor defects in the contact surfaces between shaft and seal. This will prolong the life time of the seals. Abcon B Series will work equally well with metals and rubber, Abcon B Series will not dry out or harden with age. Abcon B Series can simply be added to the oil in the header tanks by ships staff. Due to its high specific gravity the product will automatically, assisted by the pressure from header tank, find its way to the bearing and seals, immediately start working on the causes of an oil leak and restoring good sealing effect.

Abcon B Series work both ways as it stops oil leaking out as well as it stops water ingress.

Abcon B Series blends with all types of system Bio oils.


  • Stops oil leakage and water ingress
  • Minimises initial start‐up damage
  • Reduces possibility of seizing
  • Reduces wear and friction
  • Resists water washout
  • Offers high degree of residual lubrication
