Rod Seals

Advantages Rod Seal

1. Minimal break-out and dynamic slide friction. Therefore no stick-slip. Steady movement is guaranteed even at low velocities.
2. Low wear.
3. High extrusion resistance.
4. High temperature resistance.
5. Compatibility with nearly all media due to the high chemical resistance of the rod sealing ring, and a wide selection of O-ring compounds.
6. Available in diameters up to 1500 mm.
