Oil additives > Leak-Stop additives


A special additive in the power steering fluid to prevent and eliminate leaks from the steering system. Eliminates power steering, pump, and steering rack leaks, significantly extending their service life. With regular use, it increases the service life of the system by 1.5 - 2 times.

Product properties:
- Special modifiers restore the original shape, size and elasticity of the seals and power steering gaskets;
- Protects rubber and neoprene seals from drying, hardening, deformation and cracking, slowing down their aging and thus extending their service life;
- Contains components that enhance the anti-friction properties of the additive, thereby reducing wear of system elements, improving their mobility and extending the service life of the power steering;
- Provides smooth and silent operation of the steering system, reduces heat, noise and vibration of the power steering;
- Extends the service life of the pump and bypass valves;
- Can be used to prevent aging and wear of seals and gaskets, and generally to prevent system failures;
- Compatible with any power steering fluid.
