Klingersil C4430 Gasket Material is a high-performance grade of versatile gasket fibre widely used in many industries and sealing applications. This compressed, non-asbestos fibre gasket (CNAF) exhibits very good stress retention for long lasting seal performance.

C4430 is available in a large selection of thicknesses and sheet sizes. It is manufactured from a combination of synthetic and glass fibres which are bound with a NBR (nitrile-butadiene rubber) binder. This is then finished with a non-stick coating. The result is a versatile gasket sheet with very good chemical resistance, temperature tolerance and pressure resistance.

This grade is perhaps the most popular of the wide-ranging Klinger gasket sheet selection largely due to this versatility and reliable, high-grade sealing performance.

Maximum operating temperature and pressure are highly dependent on one another, and the medium being sealed. That said, a rough guideline for this material is:

Temperature: +200°C Continuous / +400°C Maximum for very short periods.

Pressure: 100 BAR

We really do suggest utilising the attached C4430 Data Sheet though as this includes pT diagrams showing the inter-relationship between maximum pressure and temperature.

Klingersil C4430 can withstand a wide variety of different chemicals and has been certified in accordance with a number of worldwide standards. These include:

  • Fire safe according to BS 5146.
  • BAM approval in accordance with UVV 28, oxygen( VGB 62) tested up to 100 bar and 85°C.
  • Approved for gas supply in accordance with DIN 3535/6. DIN - DVGW permit NG 5123AN0418.
  • Potable Water approval in accordance with WRc and AS4020.
  • TA Luft (Clean air) approval, tested in accordance with VDI 2440 at 250°C.
