KLINGER® Graphite Laminate PDM
The more highly compressed pure graphite gasket with two rough sheet metal inserts.
Adhesive-free and manufactured from expanded graphite, this gasket material features two 0.1 mm thick tanged stainless steel inserts. Ideal for high-pressure, hot water and steam at temperatures up to 450 °C, this gasket material is free of resins, impregnations or other organic compounds. Furthermore, it displays stable physical properties across the entire temperature range.
Basis composition
Expanded graphite with two 0.1 mm thick tanged stainless steel inserts.

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.
