  • 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. This versatile gasket material is a true general-purpose grade that has good compatability with a wide range of media and fluids, reasonable temperature resistance and pressure resistance. ANSI B 16.5 Flanges and the associated ANSI B 16.21 Gaskets are widely used in a variety of industries around Australia. The following sections provide more information on the ring gaskets listed on this page, the capabilities of C4430 as a gasket material, and the individual gasket sizes for each standard, ring-face table gasket up to 600NB.

C4430 CNAF Flange Gaskets to Suit ANSI Size Info.

This page lists ring type gaskets. 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 the size requirements of ANSI B16.21 and used with ASME B16.5 Flanges. This specification contains 5 different flange tables listed below:

  • ANSI 150 (Class 150)
  • ANSI 300 (Class 300)
  • ANSI 600 (Class 600)
  • ANSI 900 (Class 900)
  • ANSI 1500 (Class 1500)

Ii many nominal pipe sizes (NB), the Class 300 and Class 600 call for the same size gasket. The same is true with Class 900 and Class 1500. When this is true, a single gasket is offered that will fit both (denoted on the list as Class 300 / 600). When the specification calls for different size gaskets, individual options for each are listed.

What this means in practice is…

ANSI 150
Does not share it’s sizing with any other flange table at any nominal bore.

ANSI 300
Shares it’s sizing with ANSI 600 up to 80NB (3”). For pipes larger than this, individual gaskets are offered as the sizes differ.

ANSI 600
Shares it’s sizing with ANSI 300 up to 80NB (3”). For pipes larger than this, individual gaskets are offered as the sizes differ.

ANSI 900
Shares it’s sizing with ANSI 1500 up to 65NB (2.5”). For pipes larger than this, individual gaskets are offered as the sizes differ.

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.

In general, C4430 is compatible with…

  • Water
  • Steam
  • Oils,
  • Gases
  • Fuels
  • Alcohols
  • Moderate organic and inorganic acids.
  • Hydrocarbons
  • Lubricants
