Restoration of seals

Bardahl Stop Leak for manual gearboxes is specially developed to restore the original properties of rubber and neoprene seals. By making aged and dried-out gaskets supple again, this additive helps to effectively stop oil leaks and reduce further wear.

Improvement of oil performance

In addition to sealing leaks, this product cleans hard-to-reach areas inside the gearbox and adds new additives to the oil. This results in improved lubrication and extends the lifespan of mechanical parts.
