Grooved gaskets are excellently suited for sealing of media under extreme operating conditions, such as high operating pressures and temperatures. They combine the specific properties of soft material gaskets (great alignment onto the flange sealing surface) and metal gaskets (high stability and rupture strength). Very low diffusion level and very high density ensure very low leakage rates. Grooved gaskets are ideal replacements for problem applications associated with other similar gaskets as metal jacketed, solid metal, solid graphite or PTFE gaskets. The metal core profiling, layer thickness and material are so aligned that the layer material is highly compressed, thus presenting low cross-sectional diffusion.
Due to the reduced sealing area, only low seating stress and low bolt load are required.

- Sealing layers.
GASKET DIMENSIONS AND SIZES:
Standard sizes are made according to EN or ASME/ANSI, non-standard sizes are available on request. Dimensions of grooved gaskets can be from 15 mm to 4000 mm.
