Doniflex® GR-A is soft sealing material reinforced with tanged steel insert. Excellent thermal and stress resistance combined with very good adaptability to flange irregularities provides best service in high temperature and stress applications. It is recommended for sealing exhaust air supplies, pipes, intake and exhaust manifolds and exhaust gas recirculation systems in engines, as well as other industrial sealing applications that require high strength and thermal integrity i.e. for transmission flanges and high-pressure pumps.

Branded, without coating. A special silver colored non-stick top and bottom layer as well as other additional surface treatments (silicone, PTFE) are available on request.
