pT diagrams

The Klinger pT diagram provides guidelines for determining the suitability of a particular gasket material for a specific application based on the operating temperature and pressure only. Always refer to the chemical resistance of the gasket to the fluid.

1. In area one, the gasket material is normally suitable subject to chemical compatibility.
2. In area two, the gasket materials may be suitable but a technical evaluation is recommended.
3. In area three, do not install the gasket without a technical evaluation.

Function and durability

The performance and service life of KLINGER gaskets depend in large measure 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 observe our installation instructions.

Certain grades of Klinger sheet jointing materials can be supplied with either a wire mesh or expanded metal reinforcing.

For information on fire safe materials in accordance with API or ISO as well as the international application approvals to which Klinger materials have been tested, please contact us.
