  • Economical, General-Purpose Compressed Non-Asbestos Fibre (CNAF) Flange Gaskets.
  • Used for medium pressure pipe sealing up to 220°C.
  • Compatible with water (certified for potable), steam, fuel, oils, natural gas and diluted acids.
  • Cut to size in our Australia facilities and available in the full range of standard sizes.

Conafi Flange Gaskets are a great option for general-purpose sealing requirements. These gaskets are a step up from (most types of) rubber in terms of pressure and temperature resistance yet are still quite economical.

The styles and sizes listed on this page are all made from 1.5mm thick Conafi CNAF to suit BS 3063 Flanges and are available in Ring Face. 

Conafi Gasket Sheet Information

Conafi is a general-purpose gasket fibre sheet material that is made from a combination of mineral and aramid fibres that are secured with an NBR (Nitrile Butadiene Rubber) binder. Gaskets cut from this quality material offer several benefits, including:

Wide Ranging Chemical & Media Compatibility.

Conafi Gaskets have been engineered to hit the sweet spot between versatility and economy. To achieve this, the material has been produced using only quality ingredients with the result being a gasket material with excellent compatibility with various types of media, fluids and chemicals.

Conafi is highly compatible with:

  • Water.
  • Potable Water (Certified by KTW).
  • Gas (DVGW Certified).
  • Oils.
  • Petrol.
  • Salts.
  • Alkalis.
  • Mild Acids.
  • Many other types of chemicals, gases and fluids.

Conafi CNAF Gasket Material PT DiamgramGood Temperature Resistance.

Conafi generally withstands sealing applications with temperatures between -30°C and +220°C. Like most gasket materials, the maximum operating temperature of Conafi Gaskets have a direct relationship with the pressure they are sealing.

The chart on the right illustrates this relationship showing that at its maximum pressure rating (6MPa) Conafi should only be used for applications up to about 180°C (this is also true when used to seal steam). Higher temperatures are possible where the operating pressure of the joint is lower.

Excellent Sealing Characteristics.

In addition to Conafi’s ability to handle a wide range of temperatures and media, this material has excellent sealing properties. Many are summarised in the table below with more information available on the attached Conafi Technical Data Sheet.

Base Materials Kevlar Aramid Fibres, Mineral Fibres and an NBR Binder
Maximum Continuous Operating Pressure 6 MPa
Density 2 g/cm³
Compressibility 11.7% (ASTM F 36)
Recovery 58.8% (ASTM F 36)
Creep Relaxation 20.3% (ASTM F 36)

Flange Gaskets to Suit BS 3063 Size Info.

This page lists ring types 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.

Theseg askets 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.
