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.

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.
