The gasket comprises a corrugated stainless steel core (1.4404) covered with graphite layer on either side using the adhesive-free LE-SAFE technology and a stainless steel inner eyelet (1.4404). The inner eyelet prevents the graphite layer from impacting the flow medium.LE-SAFE corrugated gaskets impress by a very high pressure application limit, low leakage rate and are therefore suitable for extreme operation conditions [e.g. cryogenic, oxygen, hydrogen].

BAM [Bundesanstalt für Materialforschung und -prüfung] holds a critical view and does not recommend using, zircon or zircon alloys, titanium and titanium alloys or alloys containing titanium [e.g. stainless steels 1.4541, 1.4571] or metallic materials containing more than 2.5% aluminum for applications involving oxygen. However, the stainless steel 1.4404 used in all LE-SAFE products as a standard material is suitable for this [other suitable metallic materials are available on request - e.g. 1.4828, Hastelloy etc.]
