Bonded Seal - Biggest European Stock

We produce and stock millions of metal and rubber washers; metric and imperial sizes. Stainless steel or steel; NBR, FKM

We manufacture and maintain a large permanent stock of bonded seals and metal-plastic gaskets (also known as Usit gaskets or metal-rubber washers). As manufacturers specializing in high-pressure sealing systems, we produce solutions according to standards in standard metric and imperial sizes (BSP, NPT, UNF), as well as custom-developed solutions for demanding mechanical and hydraulic environments. Advantages of our high-pressure metal-plastic gaskets: Custom manufacturing and special projects: We machine the metal body and vulcanize the rubber lip to adapt to non-standard dimensions or complex technical requirements. Self-centering design: Our metal-plastic washers incorporate an internal lip that positions them concentrically on the thread, speeding up assembly and preventing leaks due to misalignment. Continuous stock and immediate delivery: We have thousands of part numbers ready for shipment in hydraulic fittings, avoiding production line or maintenance downtime. Reusable airtight seal: The chemical bond between the metal ring and the elastomer withstands high pressure impulses and vibrations without suffering deformation or extrusion.
