Graphite fiber
The graphite-fiber composite flat gasket is a cutting-edge sealing solution for heavy-duty applications. Combining the flexibility of graphite with the mechanical strength of aramid fibers, it is designed to withstand extreme thermal and chemical stresses without compromising safety.
Custom-cut graphite-fiber flat gasket
We work with materials such as Doniflex® G-U, an advanced composite combining graphite, aramid fibers, and mineral fillers. It is engineered to meet the most demanding industrial requirements.
This material stands out for its excellent physicochemical properties. It offers high compressibility and flexibility, allowing it to conform perfectly to irregular surfaces.
Graphite-fiber flat gaskets are ideally suited for steam circuits, heating systems, and chemical industry installations. They feature a high-performance anti-stick coating for effortless replacement, even after prolonged high-temperature service. Available as custom-cut gaskets.
