Production of seals
We use our Sealmaster lathes to manufacture seals up to a diameter of Ø535mm. We use materials such as NBR, HPU, Viton, POM and PTFE bronze, which are known for their high resistance and durability. If a larger dimension or a special material is required, our experienced team will be happy to advise you at any time in order to find the optimum solution.

Frequently asked questions
How do I choose the right hydraulic seal?
Choosing the right hydraulic seal depends on factors such as pressure, temperature and the medium with which it comes into contact. It is important to know the specific requirements of your application in order to select the right seal. Contact us for expert support and individual recommendations for your hydraulic seals.
How do I measure a hydraulic seal correctly?
To correctly measure a hydraulic seal, you must first determine the type, then precisely determine the inner diameter, outer diameter and thickness of the seal. Use suitable measuring tools such as calipers or micrometers to obtain accurate measurements. Visit our YouTube page, where we provide helpful videos on measuring different types of gaskets.
What material is a hydraulic seal made of?
Hydraulic seals consist of various materials that are selected depending on the application and requirements. Commonly used materials are
- Polyurethane (PU): Good abrasion resistance and high load capacity. Standard material for most hydraulic cylinders.
- Nitrile rubber (NBR): Resistant to oils and fuels, ideal for general applications.
- Fluororubber (FKM): Resistant to high temperatures and aggressive chemicals.
- Silicone (SI): High temperature resistance and flexibility at extreme temperatures.
