Our grooved gaskets have invariably proven their worth in all industrial sectors, also in the case of difficult
sealing tasks. These are found mainly in both conventional power plants as well as in the primary circuit of
nuclear power plants.
On account of the good resiliency properties the grooved gaskets are ideal for applications with temperature-
and pressure-change stresses. They are therefore also often referred to as composite gaskets. The sealing
surface of the metal core consists of a 45° profiled sealing surface, on which a soft material layer is installed.
The latter consists exclusively of high-quality materials, such as graphite or PTFE. The grooved gaskets can seal
virtually all media, which is due to the selection of exclusively first-class carrier materials and sealing liner.
The enormous advantage of the grooved gasket is the interplay of low minimum surface pressure and high
permissible maximum surface pressure, on account of which an outstanding effectiveness can be achieved. This
characteristic permits a large range of applications, this gasket is as such not only deployed for the sealing of
steam, water, alkalis, organic and inorganic gases, aliphatic and aromatic hydrocarbons, alcohols, ethers,
ketones, but particularly also in the case of many other chemical substances.
The application temperatures are from -200 °C up to +1000 °C. In addition, the grooved gaskets can
without a problem be used to reliably seal a total pressure of up to 400 bar. The grooved gaskets from our
assortment can be used for all standardised flanges from DN 10 up to DN 3600. In case you need special
forms, we can of course also offer tailored solutions, which are also distinguished by a high degree of

the case of lids for fittings in the steam cycle.
