Rubber-metal-gasketsare used where safe sealing ofconventional up to special in-dustrial media such as gases and liquids are required underusual installation conditions like temperatures, pressures and forces.

KLINGER®KGS gaskets are suitable for all flange materials.

A flange connection has to be always treated as a coherent system, because the sealingfunctions is determined by the interaction of individual elementsincluding flanges, gaskets andscrews (clamping elements - VDI 2290).

Fields of application

Safe sealing of water, gas, air,acids, alkalis and hydrocarbonswith low sealing forces at temperatures up to 200°C, depending on the elastomer type.

Function and durabilityThe function of KLINGER Gasketsmainly depends on the storage andinstallation conditions on which, we as a supplier, do not have any influence. That is why we only ensure perfectcondition of the material.

Please also observe our instal-lation instructions on this. In case there are special approval regulations, they have to be ob-served.

As for other media or applicationconditions, we would be glad to provide you with further information.

Subject to technical changes.No responsibility is accepted for theaccuracy of this information.Status: May 2015

The following instructions have to be observed so that a reliablesealing connection can be ensured.

1. Gasket selectionThe suitable material quality can be selected from the KLINGER®

information sheet - above all, fromthe resistance chart.

2. FlangesFlanges should be parallel, metallic,clean and dry, the gasket has to bemounted centrically.Please ensure the correct gasket dimensions. The gasket should never tower intothe throughhole (media flow)!

The outer diameter of the KLINGER®KGS gasket is adaptedto the bolt circle of the flange. Therefore safe centering at thescrews is ensured.

3. InstallationThe installation of the gasketsshould be carried out without usingany grease or oil containing sepa-rating/sealing agents or similar.

In no case, oil or grease con-taining products may be used, because they have a negative influence on the safety of the wholeflange connection..

4. ScrewsWhen installing the screws, theyhave to be tightened evenly in twoto three steps crosswise.

The screws should be lubrica-ted. Pay attention to the tighteningtorques.

5. Retightening“Retightening" is not required ifthese instructions are followed.

6. Multiple useFor reasons of safety, the multipleuse of gaskets is generally not recommended.

On request, please make use of advice of the KLINGER GmbH!

KLINGER offers you excellent sealing products for all fields of application
