Gaskets & Sheet Jointings

These exceptionally versatile gaskets solve many flange sealing problems for industry. They have either a metal core with sealing materials on both flat surfaces, or a pliable core encased in a thin metallic casing.

A range of highly proven non-asbestos sheet jointings that covers flange gasket duties with most fluid media from ASME Class 150 to Class 600 ratings, plus some special applications.

Our range of Supagraf^® expanded graphite jointings combines excellent chemical resistance with an exceptionally wide temperature range to provide outstanding sealing integrity over extended periods.



Prime features of Supagraf^® jointings

• Temperatures from cryogenic to above +400°C in oxiding environments.
  
• Maximum working temperature of +2500°C in inert conditions under certain circumstances.
• Excellent resistance to stress relaxation, even at elevated temperatures. 
• Totally compatible with steam, air and water.
• High levels of joint stability.
• Accommodates flange distortions where traditional sheet jointings fail to seal.   

James Walker's Fluolion^® PTFE, WL Gore's ePTFE, and Garlock's Gylon^® modified-PTFE gasket products provide outstanding chemical resistance for duties where hygiene and non-contamination are essential.






They offer many unique features:

• Outstanding chemical resistance.
• Non-corrosive, non-wetting, non-contaminating and odourless.
• Tolerate temperatures between -200°C and +260°C.
• Excellent electrical and thermal insulation when in virgin PTFE form. 

Nebar^® cork-elastomer jointings are the obvious choice for numereous flange sealing duties with oils, fuels and water in the electrical, automotive, marine, aerospace and general machinery sectors.

We in-house process and/or supply wide ranges of commercial and specification grade elastomers for flange sealing and other duties.

We offer a variety of gasket types or materials for specific applications - plus our compact hand tool for cutting circular flange gaskets from compressed fibre jointings, rubber and cork-elastomer sheets. Also, our RotaBolt^® tension control fasteners are widely used on high integrity flange jointed systems.

The vital role of the flange gasket is too often overlooked. Our on-site and workshop-based services are based on the vast technical expertise of James Walker companies in the selection, manufacture and supply of the optimum gasket products and flange sealing capabilities.

Our CAD/CAM controlled water-jet, abrasive water-jet, and laser cutters produce precision cut gaskets and other complex profiles to any shape, size and quantity from virtually any sheet material.
