KLINGERSIL Hochdruckdichtung

KLINGER® Graphite Laminate SLS

The pure graphite gasket with a smooth stainless steel insert

Combining pure exfoliated graphite with stainless steel foil reinforcement, this gasket material promises improved cutting and handling.

Basis composition

Expanded graphite and a plain glued stainless steel insert.

Areas of application

Thanks to its graphite-based conformability characteristics, it is suitable for low bolt-load and damaged flange scenarios. Resistant to virtually any type of medium, it is also temperature-resistant (up to 450°C) and highly compressible.
