Custom gaskets

Let’s us design your custom gaskets for best bespoke solution – optimally designed for your application

Custom gaskets are sealing solutions designed to meet the specific needs of industrial applications, whether in aerospace, petrochemical, hydroelectric, automotive, or water treatment. The gaskets, manufactured in a wide range of materials such as rubber (nitrile, EPDM, silicone), advanced polymers (PTFE, Viton), metals (stainless steel, copper), or composites (aramids, graphite), offer exceptional performance in the face of the most extreme pressures, temperatures, and chemical environments.

Their custom design allows them to adapt to complex shapes, specific sizes, or unique conditions, ensuring a reliable seal for flanges, valves, heat exchangers, or other critical equipment. Versatile and robust, custom gaskets are essential for ensuring the safety and longevity of systems.

Whether you’re looking to seal an electric battery cover, a pharmaceutical mixing tank, or the modules of the first permanent lunar base, ELASFOR will be there to take the time to study your project in detail. We excel at providing custom gaskets, designed to precisely meet our customers’ needs. Whether you need a gasket in a specific material to withstand corrosive fluids, a custom shape for specific equipment, or a solution for very high pressures, our expertise allows us to supply gaskets in all known materials and all imaginable dimensions.
