Static Seals

are used in all industrial sectors. They come in a variety of shapes and materials, e.g. for extreme temperatures, media and pressures, and with foodstuff approvals or sterilisable for the medical and pharmaceutical industries.

Static Seals

Static seals for radial sealing or as flange seals are available for a wide range of applications. Seals for pipe connections, milk pipe seals according to DIN 11850 or DIN 11851 and clamp seals – or seals for clamp connections – according to DIN 32676. Many of these seals are often a good solution for sealing with little dead space and are available with foodstuff and pharmaceutical approvals, as well as in detectable materials.

For extreme temperatures that no longer permit the use of elastomers and plastics, we offer metal seals that can be supplied in a wide variety of materials and with various coatings, suitable for the application in question. Other high-temperature materials such as ceramics, glass or graphite (also with tanged sheet insert and non-stick coating) are also available.
