As a system partner, Zilken supplies seals and sealing components for the full range of industrial applications: from standard O-rings and custom-made products to high-temperature gaskets and standard-compliant flange gaskets.
From NBR, FKM, and EPDM to high-performance materials such as FFKM and PTFE: We understand the properties and application limits of common sealing materials and can help you select the right one based on the medium, temperature, and pressure.
Whether it's DIN EN 1514, DIN ISO 3601, TA-Luft, FDA, or DVGW: We take into account the standards and approvals relevant to your specific application and provide the necessary documentation.
Custom dimensions, special materials, colors, or hardness grades are all part of our daily business. Just tell us your specifications, and we’ll find the right sourcing solution.
From cryogenic temperatures and vacuum to high temperatures and high pressure: We supply seals for demanding industrial operating conditions and a wide range of requirements regarding durability and conductivity.

Thanks to a network of over 400 specialized suppliers and decades of procurement expertise, Zilken ensures that customers always receive the right gasket—whether it’s a standard mass-produced part or a hard-to-find custom-made gasket.
To support its expansion into North America, Zilken developed an integrated assembly kit concept for HSP high-voltage devices. Up to 62 items are assembled into complete, ready-to-assemble kits and made available directly on the production line according to production logic: ready to assemble.
The result: lower process costs, consistent material availability, and a standardized production logic for the sites in Canada and the U.S.
Whether it’s assembly kits based on a bill of materials or custom assemblies, Zilken handles picking, packing, and labeling in accordance with the production process. The parts arrive exactly where they’re needed, ready for assembly. This results in tailor-made solutions for kitting and sets that significantly reduce the workload for purchasing, warehousing, and assembly.
Zilken not only handles the delivery of individual items, but also coordinates bill of materials, suppliers, and logistics for complex procurement requirements—from individual parts to ready-to-assemble kits.
The range is broad: from classics such as NBR, FKM (Viton), and EPDM to high-performance materials such as PTFE, FFKM, and silicone. The right material depends largely on your application; please contact us, and together we’ll find the right solution. We source materials that we don’t have in stock through our network.
Yes, and we go beyond simply delivering the product. We contribute our technical expertise: in selecting seals that comply with standards, in addressing questions about approvals and regulatory requirements, and in technical specifications.
If you're unsure which standard or certification your application requires, we'll work with you to clarify this and provide the appropriate documentation.
It’s especially worth talking to us when dealing with challenging operating conditions. Whether it’s aggressive media, high temperatures, high pressure, or requirements for electrical conductivity or insulation: we listen, understand what really matters in your application, and work with you to develop the right material and design solution. You don’t need to come to us with the perfect specification already in mind—often, it only emerges through our discussion.
Static and rotary seals are at the core of our product line. We source dynamic hydraulic seals—such as rod seals, piston seals, and groove rings, as well as scrapers and guide elements—through our supplier network.
Yes, custom dimensions and customer-specific designs are among our areas of expertise and often serve as the starting point for our collaboration. Based on your drawing, specification, or sample, we review the dimensions, material, color, hardness, and relevant standards and certifications. We then assess the technical and economic feasibility and source the appropriate design through our supplier network.
Fasteners for every application: screws, nuts, rivets, and bolts—DIN-compliant parts and custom-made products, from small quantities to large-scale production runs.
Hydraulic technology for power and precision: pumps, cylinders, valves, and power units for hydraulic and pneumatic systems. Components and assemblies according to DIN standards and drawings.
Elastomer Components for flexible applications: Molded rubber parts, dampers, and profiles offer reliable solutions, ranging from small-batch production to individual custom fabrications.
