The design of a rod or also piston rod seal is crucial for the function of the entire assembly. A rod seal is internally sealing and is usually knotted into a closed groove. Some profiles require a split installation groove. A number of profiles are offered on the market – we will assist you in making the perfect choice.
Standard profiles
The standard profiles shown below are seals that represent the state of the art. We manufacture these standard seals in-house or supply them as moulded parts from approved partners for all required groove dimensions in a variety of materials. Even inch and intermediate dimensions, but also diameters up to 3000 mm can be realized.
Depending on the quantity, the material and your requirements, we will offer you seals in the appropriate manufacturing process – everything from one source!

Pressure range: | up to 400 bar* |
Sliding speeds: | up to 0,5 m/s |
Temperature range: | -55 to +220 °C (depending on material) |
* Special solutions for lip seals for higher pressures up to 700 bar are possible!
Pressure range: | up to 600 bar |
Sliding speeds: | up to 15 m/s |
Temperature range: | -55 to +280 °C (depending on material) |
