99% pure, flexible, expanded graphite splice with expanded stainless-steel mesh insert. The material offers excellent medium strength and offers maximum reliability in load changes. The metal insert (1.4404, AISI 316 L) is particularly resistant to acids and, thanks to its 3D dimensional geometry, significantly improves the containment properties of the joint itself. The combination of the high-quality reinforced graphite and the expanded metal insert has many advantages: pressure is optimally distributed, containment is optimised by the material's recovery properties, the gaskets are reduced in size due to the grid's gemoetric properties, fault tolerance during use is optimal, and the gasket is safe in handling even when the material is accidentally damaged.
