KLINGER®sealex

Characteristic & main applications

Klinger Sealex is a joint sealant material manufactured from specially processed 100% pure PTFE in a unique process. It is composed of specially prepared fluorocarbons with excellent resistance to aggressive chemicals as well as offering secure sealing under high internal pressures.

The high compressibility of Sealex® enables it to effectively fill flange imperfections for a tight, leak-free seal.

Unlike conventional PTFE which is prone to cold flow, Sealex has good creep resistance and bolt torque retention properties. Its form-in-place versatility also cuts maintenance and storage costs. It has an adhesive backing to assist installation.

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.


Temperture: -196 to 260°C
Pressure: up to 140 bar depending on application

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.
