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.

Function and durability
The performance and service life of KLINGER gaskets depend to a large extent on proper storage and fitting - factors beyond the manufactor’s control. We can, however, vouch for the excellent quality of our products. With this in mind, please also take note of our installation manual.
