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, which 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, which 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

CERTIFICATES & APPROVALS

  • DIN-DVGW
  • Fire-Safe acc. to DIN EN ISO 10497
  • BAM tested

Benefits

  • Provides excellent adaptability to any sealing surface
  • Seals irregular flanges
  • Conforms easily
  • Stable physical properties over the whole temperature range

Function & Durability

The performance and service life of KLINGER gaskets depend to a large extent on proper storage and fitting – factors beyond the manufacture’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.
