  • Quality Pipe Flange Gaskets made from C4430 premium quality compressed, non-asbestos fibre gasket material.
  • Ring type gaskets made from this universal style of gasket sheet with outstanding stress retention and resistance to hot water and steam.
  • Very good compatibility with oils, fuels, alcohols, moderate acids, hydrocarbons, lubricants and more.
  • Cut to size in our Australia facilities and available in the full range of standard sizes.

Klingersil C4430 Flange Gaskets are widely used for medium temperature and medium pressure sealing. These ring type gaskets are produced in our Australian facilities to suit the size requirements of BS 3063 Table D and/or Table E Flanges.

Flange Gaskets to Suit BS 3063 Size Info.

This page lists ring types gaskets (full face for the same flange style listed here). This style of gasket is designed to sit inside the bolts of the flanges and is known by quite a few names, including:

  • RF Flange Gaskets.
  • IBC Gaskets (Inner Bolt Circle).
  • Raised Face Gaskets (as they are often used on raised face type flanges).
  • Ring Face Gaskets.

The gaskets featured on this page are all cut to suit BS 3063 Flanges in either Table D or Table E configurations (the two most common). In almost all pipe nominal bores (except 150NB, 200NB & 300NB) there’s no difference in gasket size between Table D or Table E (the gasket fits both) when using ring type gaskets.

For those where there is a difference, both Table D and Table E variations are offered separately.

We are pleased to also offer Full Face C4430 Gaskets to suit these same flange specifications. You can browse the full Table D & Table E Full Face C4430 Gasket range here.

C4430 Pipe Flange Gaskets Information.

Gaskets made from C4430 exhibit good all-round sealing capabilities and compatibility with a wide range of fluids and media. Performance characteristics include:

Good Pressure and Temperature Resistance.

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 utilised the attached C4430 Data Sheet though as this includes pT diagrams showing the inter-relationship between maximum pressure and temperature.

Certified for Use in a Variety of Critical Sealing Applications.

Klingersil C4430 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 WRS and AS4020.
  • TA Luft (Clean air) approval, tested in accordance with VDI 2440 at 250°C.

For more information on the various certifications and approvals bequeathed on this gasket sheet please refer to the attached C4430 Data Sheet for a full and comprehensive listing.

Good Chemical Resistance.

The full list of chemicals that C4430 Gasket Material can or cannot seal is incredibly long and detailed. The list below is presented as a summary only. For more information on a specific medias’ compatibility please do contact us and we’ll be happy to help.
