KLINGERSIL® C-4409

More safety at high thermal and mechanical stress

 
KLINGERSIL® C-4409 has an expanded metal reinforcement. The galvanized low carbon steel insert makes this material suitable for conditions with high thermal and mechanical stress.

C-4409 is excellent in hot gases and can replace spiral wound gaskets in some applications.

This material is manufactured with synthetic fiber reinforced with a nitrile binder.

The pressure/temperature graphs shown are the most current method of determining the suitability of a gasket material in a known environment. However, chemical compatibility must also be considered.

In area 1 the gasket material is suitable using common installment practices subject to chemical compatibility

In area 2 appropriate measures are necessary for installation of the gasket to ensure maximum performance. Please call or refer to KLINGERexpert for assistance.

In area 3 do not install gaskets in these applications without first referring to KLINGERexpert or contacting Thermoseal Inc.'s technical support service.
 
The ability of a gasket to make and maintain a seal depends not only on the style and quality of the gasket material, but also on medium being sealed, the flange design, the amount of pressure applied to the gasket by the bolts and how the gasket is assembled onto the flanges and tightened. These factors are beyond the manufacturer's control. Please take note of our installation manual in TECHNICAL RESOURCES.
