Piston Seals

A piston sealing is used for outside sealing. Its design is crucial for the functioning of the entire assembly. 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. Depending on the quantity, the material and your requirements, we will offer you seals in the appropriate manufacturing process – everything from one source!

Profiles according to customer preferences

If you have conditions which cannot be optimally solved with a standard profile, we can also manufacture a sealing system according to customers’ drawings or develop a system. In this field we are a development partner and are perfectly equipped to design the ideal product for you.

Choosing the correct profile

The more information is known, the better a sealing system can be adapted to a specific application. To choose the right profile and the optimal material, the following criteria are vital:

  • installation space
  • double or single-acting
  • pressure range
  • temperature range
  • medium
  • lifting speed
  • counter surface
  • installation option
  • friction behaviour
  • stick-slip behaviour
  • tightness
  • service life expectancy
  • price and availability
