Flange Gaskets

Queensland Gaskets manufactures and supplies flange gaskets for pipework, equipment and industrial applications across Australia.

We manufacture cut gaskets to common Australian and international flange standards, including AS 4087, AS 2129 and ANSI specifications, with a range of commercial off-the-shelf gaskets also available for replacement and urgent requirements.

Flange Gaskets to Suit Common Standards

Getting the correct flange gasket starts with matching the gasket to the flange standard, nominal size and pressure class.

Queensland Gaskets manufactures flange gaskets to standards including:

  • AS 4087
  • AS 2129
  • ANSI B16.21
  • DIN 2690
  • BS 4865

Have designs and know your gasket requirements? Get in touch to discuss so we can quote your project.

What Size Flange Gasket Do I Need?

Flange gaskets fit between two mating flange surfaces to create a seal within the connection.

Gasket dimensions are generally determined by the nominal bore of the pipe and the flange standard being used. Depending on the system, the specification may also include a table, PN rating or ANSI class.

Useful information can include:

  • Nominal bore or DN/NB size
  • Flange standard
  • Table, PN or class rating
  • Gasket dimensions
  • Thickness
  • Required material

If you have a drawing, flange specification or existing gasket details, these can also be supplied with your enquiry.

Choosing the Right Flange Gasket Material

The right gasket material depends on the application and the conditions the gasket will experience in service.

Factors that may affect material selection include:

  • Operating temperature
  • Operating pressure
  • Water, gas or other process media
  • Oils, fuels or chemical exposure
  • Required gasket thickness
  • Flange and equipment requirements

Queensland Gaskets works with a broad range of gasket materials, including rubber, fibre, high-temperature materials, plastics, metals and other specialist sealing products.

If you know the flange specifications but are unsure which material to use, send our team the operating conditions and media being sealed so we can review your requirements.
