O-rings of PTFE
are mainly used against aggressive media and at high temperatures of -200°C to +260°C and are resistant to virtually all chemicals.
The FEP encapsulated seals
consist of an elastomer core and a seamless capsule of FEP are resistant to virtually all media. It can therefore be used in applications requiring high chemical resistance and elasticity of the seal.
The operating temperature of -60°C to +200°C with a silicone core and -25°C to +200°C with a core of fluorocaoutchouc.
Gasket rings 4FC
are used in the foodstuff, chemical and pharmaceutical industry. They are used in clamp connections with inside profile (knuckle clamps per ISO 2852 and DIN 32676) and in pipe and tube connections per DIN 11850 and DIN 11851 respectively.
Gasket rings for food industry fittings
are mainly used in the foodstuff industry to seal fittings and screwed pipe connections according to DIN 11851. Many special sizes are also available in various materials and profiles, e.g. for use in knuckle thread connections according to DIN 11887 and fitting connections according to DIN 11852.
are mainly used for static sealing of screw and small flange connections. Advantages are the simple fitting, a wide range of applications and their high sealing performance.
with intermediate layers of PTFE or graphite have proven their worth as reliable sealing elements in many fields of process plant engineering and the chemical industry. They are mainly used where the seal is exposed to extreme conditions
such as high temperatures, high pressures or aggressive media.
PTFE flat gasket tapes
are mainly used for static sealing of flanges, containers and covers and in hydraulic and pneumatic systems. Being quick and easy to fit, malfunctions that would normally lead to relatively long and expensive production stoppages can be repaired immediately.
