KLINGER® Graphite Laminate PSM
The pure graphite gasket material with a stainless steel tang insert
KLINGER® Graphite Laminate PSM has a 0.1 mm thick perforated stainless steel insert. The insert aids material handling properties and also increases the blow-out resistance. The insert is mechanically bonded to pure exfoliated graphite and therefore does not rely on adhesive.
Stable physical properties over the whole temperature range. KLINGER® Graphite Laminates PSM is suitable for hot water and steam at high temperatures up to 842°F (450°C).
In order to prevent the gasket material from sticking to the flange surface (even at high temperatures), the graphite surface can be given a non-stick coating at the customer's request. With this process, the gasket material's surface is coated and not impregnated.

The ability of a gasket to make and maintain a seal depends not only on the style and quality of the gasket material, but also on medium being sealed, the flange design, the amount of pressure applied to the gasket by the bolts and how the gasket is assembled onto the flanges and tightened. These factors are beyond the manufacturer's control. Please take note of our installation manual in TECHNICAL RESOURCES.
