Notes
6 notes- *Production can be carried out in different dimensions.
- Meter / weights may vary.
- General application area, provided that chemical compatibility conditions and known installation principles are applied.
- Maximum performance is ensured by adhering to the appropriate technical values in connection design and gasket installation. It is recommended to seek consultancy services.
- Limited application area. Technical consultancy is mandatory.
- NOTE: The information provided above has been prepared with many years of experience in the production and operation of gasket materials. Considering countless assembly and operational conditions, it is not accurate or technically sound to expect the same results from gasket materials in all applications. Therefore, the information provided does not warrant any right to complaint by the user. It is strongly recommended that you test the gasket material under your own operating conditions to reach a definitive conclusion before proceeding to continuous application. Our expert personnel will be pleased to assist you in the selection of gasket materials.
