Seals have been our field since 1975.

We work with everything from Bonded Seals and O-Rings to ED Seals, WALFORM seals and hydraulic sealing solutions. Our range includes both standard products and more specialised solutions in materials such as NBR, FKM, HNBR, EPDM, FFKM, polyurethane and PTFE.

For us, a seal is about more than finding the right dimensions. Media, temperature, pressure, material selection, design and documentation requirements can all be decisive when choosing the right solution. We therefore place great emphasis on understanding the application and helping the customer find the right product.

With more than 50 years in the industry, STEMA has built experience supplying sectors including hydraulics, marine and offshore, process industry and mechanical industry. We supply individual products, larger series and products adapted to specific technical requirements.

As a small and specialised company, we have short decision paths and close contact with our customers. This allows us to remain flexible, respond quickly to technical questions and work with products that can be difficult to source through ordinary distribution channels.

Our goal is simple: to be a knowledgeable and reliable partner when the customer needs the right seal – whether the solution is standard or requires something more.
