Flange Gaskets to Suit AS2129 Sizing Info.
The gaskets featured on this page are the full-face style of rubber flange gasket. These gaskets take up the full face of the flange, with holes cut for the bolts. Both ring and full-face gaskets can be used on these flanges depending on particular requirements and user preferences.
AS 2129 Flanges are most commonly found in either AS 2129 Table D or AS 2129 Table E which is why gaskets for both are listed here. That said, there are quite a few other tables made and gaskets for these (e.g. Table A, C, F, H) can also be produced upon request.
Why are some Table D and Table E Gaskets the same size while others aren’t?
The AS 2129 Flange Specification is like many others (e.g. ANSI 150) in that many of the smaller sized flanges (and consequently, gaskets) are the same across tables. In the AS 2129 Spec, gaskets made to suit flanges with a nominal bore of up to 80NB are the same no matter if the flanges are listed as Table D or Table E. After this, sizes do differ.
The table below provides more specifics on this.

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.
