Characteristic & main applications

Excellent corrosion resistance together with superior creep resistance and seal ability create a high-grade gasket material for a wide application field.

The best choice for economical plant-wide use on services to 260°C and pressures up to 200 bar subject to application details.

Also available in KLINGER®soft-chem Rigid form.

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.
