The gaskets are made from sheets consisting of a natural or synthetic rubber compound with a suitable vulcanized. They are particularly suitable for corrosive fluids and plastic pipes. The use of rubber seals is limited by the properties of the material itself, which guarantees excellent performance up to a maximum temperature of 100°C and a maximum pressure of 20 Bar. The most commonly used types of rubber are nitrile, isobutyl, polycroroprene (neoprene) and ethylene-propylene copolymers (Dutral- EPDM)
