Graphite Gaskets and Sheeting Material 

Graphite has become a very popular gasket choice for sealing applications requiring high performance combining excellent chemical resistance with an exceptionally wide temperature range from cryogenic to above +400⁰C and having excellent resistance to stress relaxation at elevated temperatures. 

This exfoliated graphite material is available in purity grades of 95% to 98% and 99.5% for nuclear applications 

There are many different versions within this family of graphite based materials ranging from plain homogenous graphite to being laminated and reinforced with stainless steel, nickel, aluminium and many other metals should such service conditions require. Materials are also available with ‘multi-layers’ offering even greater resistance to higher pressures or with polymeric layer ‘clean’ coating to aid handling. 

  • Outstanding resistance to high and low temperatures 
  • High compressibility 
  • Resistant to virtually all media 
  • High pressure  
  • Unlimited storage life  

Although we have many versions available within the graphite family most applications are covered with four primary options 

Plain Homogenous Graphite 

This material is manufactured from expanded graphite foil without any form of insert or reinforcement. This is available in purity of 98% for standard grades and 99.5% ultrahigh purity for use in applications within the nuclear industry. 

  • Maximum Temperature (oxidising media) +400⁰C 
  • Maximum Temperature (inert/reducing media) +2500⁰C 
  • Minimum Temperature -200⁰C 
  • Low coefficient of friction and excellent residual stress 
  • Very easy to cut 

Nickel Reinforced Graphite 

This is a jointing of 98% purity exfoliated graphite sheet with a reinforced adhesive bonded layer of nickel foil. Recommended for use in general sealing applications.  

  • Maximum Temperature (oxidising media) +400⁰C 
  • Maximum Temperature (inert/reducing media) +1000⁰C 
  • Minimum Temperature -200⁰C 
  • Excellent sealing integrity 
  • Very easy to cut, handle and install 

    Stainless Steel Reinforced Graphite

    This is a jointing of 98% purity exfoliated graphite sheet with a reinforced adhesive bonded layer of flat 316 stainless steel. Recommended for use to seal a wide range of media in both high and low temperature and pressure applications.

     

    • Maximum Temperature (oxidising media) +400⁰C
    • Maximum Temperature (inert/reducing media) +700⁰C
    • Minimum Temperature -200⁰C
    • Excellent sealing integrity
    • Very easy to cut, handle and install
    • High Compressibility
    • Resistant to virtually all media
    • Good leakage properties

    Stainless Steel Tanged Graphite 

    This is a jointing of 98% purity exfoliated graphite sheet with a reinforced mechanically bonded layer of tanged 316 stainless steelThis insert allows the product to be used for applications involving high sealing stresses and requiring high blow-out resistance in industries such as petrochemical and process. 

    • Maximum Temperature (oxidising media) +450⁰C 
    • Maximum Temperature (inert/reducing media) +2500⁰C 
    • Minimum Temperature -200⁰C 
    • Exceptional resistance to blow-out and crushing 
    • Strong composite construction without adhesives 
    • Excellent resistance to steam 
    • Extra strength for ease of handling and installation 
    • High Compressibility 
    • Resistant to virtually all media 
    • Good leakage properties
