VIFOR KGM 4400

Basis

Gasket material based on Aramid fibre & organic fibre with NBR binder.

Application

Suitable for oils, fuels, lubricants, alcohols, gases, hydrocarbons, steam, water, cooling liquids, most diluted acids and alkalies for medium stress conditions.

Factors affecting on the gasket

The suitability of a gasket material for an application is dependent upon a multiplicity of factors as shown in the above digram. Max. temperature and pressure values can not define the suitability for application. It is always advisable to consider these factors when selecting a material for a given application.

1 This area refer , the gasket material is normally suitable subject to chemical compatibility.

2 This area refer, the gasket material may be suitable but a technical support is recommended.

3 This area refer, do not install the gasket without technical evaluation.

All information and recommendations given in this brochure are correct to the best of our knowledge . However , in view of the wide variety of possible installation and operating conditions one cannot draw the finel conculusion in all application cases regarding the behaviour in a gasket joint . Therefore , information can only serve as a guideline.
