  • Economical gaskets for sealing at low pressures & temperatures.
  • Cut in our Australian factory to the precise size requirements of BS 3063.
  • Full range of standard flange tables available. Custom size gaskets also available upon request.

Natural Rubber Insertion (NRI) Flange Gaskets are often used in low temperature and low-pressure sealing. Cut in our Australian factory from our Natural Rubber Insertion sheet, the gaskets featured on this page are all designed to suit BS 3063 Table D and/or Table E flanges.

Widely used in many different industries, Insertion Rubber Gaskets are suitable for sealing applications where temperatures are between 0°C and 70°C. They are often used for hydro-testing or permanent, low pressure flange sealing because of their economic nature.

For more information on this material, please consult our Natural Insertion Rubber Technical Data Sheet. For more info on the gaskets, read on.

Flange Gaskets to Suit BS 3063 Size Info.

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 some pipe nominal bores (e.g. 15NB, 80NB) there’s no difference in gasket size between Table D or Table E (the gasket fits both). In others, there are differences in number of holes or hole diameter.

Where there are differences between Table D and Table E; both are offered. Where there are no differences, a single gasket is listed here which will suit both. The sizing tables below provide more information on which nominal bores use the same gasket and which require their own size.

All the gaskets listed on this page are Full Face rubber gaskets. These are so-named because they take up the full flange face and cover the bolt holes. Both ring and full-face gaskets can be used on these flanges depending on particular requirements and user preferences.

(SWP000300)

Why use a Full Face Gasket rather than a Ring?

In many situations (though not all) it comes down to preference. Full Face (aka FF or Flat Face gaskets) cover the whole flange face which can assist with achieving even compression on the gasket for some flange types. Additionally, they are easier to fit on vertical flange faces as they can be hung from a bolt before flange assembly.
