In 2016, Kastas modified the K501 design as a result of intensive R&D engineering efforts and extensive tests.
The new design performance was verified in bench and field tests, allowing us to assert that we have achieved reduced leakage and enhanced service life properties.
The new K501 design has lower static and dynamic leakage, as well as lower friction, relative to both the previous design and other piston seals available on the market. Its main advantages are:
- Lower Leakage
- Lower Friction
- Longer Service Life
