KLINGER® Graphite Laminate SLS
The pure graphite gasket with a smooth stainless steel insert
KLINGER® Graphite Laminate SLS is especially suitable for weak flanges at high temperatures up to 450°C.
Basis
The gasket material consists of expanded layers of graphite, wich are stuck to a 0.05mm thin smooth sheet metal foil made of 1.4401. The adhesive layer is applied via a precisely controlled process, wich makes it possible to keep the amount of adhesive below 1% of the amount of graphite in order to ensure uniform distribution of the adhesive.
Areas of application
KLINGER® Graphite Laminate SLS is suitable for universal use especially in combination with weak flanges (Email, glass) and for sealing of liquid level gauges.
Key features
- Stainless steel foil as insert
- Excellent chemical resistance
- Excellent high temperature resistance
Benefits
- Provides excellent adaptability to any sealing surface
- Seals irregular flanges
- Conforms easily
- Stable physical properties over the whole temperature range

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.
