Gaskets with corrugated stainless steel core

The gasket comprises a corrugated stainless steel core with graphite layer on both sides. Layers and corrugation design are adjusted to ensure crest coverage of 0.1 to 0.2 mm when assembled thus achieving a very low cross-sectional diffusion due to highly compressed graphite in these areas.
Even under low seating stress high leak tightness is achieved (σ VU 0,01 = 15 MPa). The gasket further features a good compression and recovery rate, blow-out safety as well as good stability and handling properties.
Corrugated ring gaskets are advantageous at fluctuating pressures and temperatures, in angular flexible or misaligned flange connections and low-stress-to-seal applications.
The gaskets are made in the form of the circle, oval, extended oval and the rectangle.

Fibre quality

The gasket comprises a corrugated stainless steel core (1.4571) partial graphite layer on both sides.
The partial facing reduces the surface area of the gasket for greater unit load. The sealing system can be used in low-stress-to-seal applications. The non-faced simplifies centric positioning between the bolts.

The gasket comprises a corrugated stainless steel core (1.4571) with graphite layer on both sides and a stainless steel inner eyelet (1.4571).
The inner eyelet prevents the graphite layer from impacting the flow medium.
