A selection of gaskets in a few different materials.

With nearly 100 years' experience in Gasket Manufacture and through using the latest CAD/CAM technology, we provide a competitive and responsive service in a range of materials, including Compressed synthetic fibre (CSF), together with Commercial Rubber, ​Neoprene, ​Nitrile, ​EPDM, Butyl, ​Silicone, Viton® and Polyurethane elastomeric sheet. In addition, we maintain large stocks of various grades and thicknesses of plain and rubber-bonded cork, gasket paper, felt, plain and reinforced graphite, vulcanized fibre, plastic and sponge materials and virgin, filled and/or expanded PTFE. As might be expected of a company with our experience, we recognise and can certify to most British and many other foreign standards.

Whilst with Ashton Seals you will also be able to enjoy the benefits of our existing drawing & template database as well as the skills of our in-house draughtsmen.


Tooling is available to produce all standard pipe flange gaskets (BST, ASA, DIN etc.) from any material.

Simply advise us of:

  • Grades required
  • Thickness
  • Flange specification (e.g. BS 10, ASA 300, BS 4504)
  • The nominal bore
  • Whether inside bolt circle (ring joint) or full face

For individual requirements to customer specification, new tooling can be produced and gaskets cut in many instances on a 24-hour basis.

Should press cutting not be practical or economical we have the ability and experience to produce hand-made joints to any shape or size. A complete gasket cutting service is available from Ashton Seals in a large range of materials.

Graphite and PTFE Packings.


Ashton Seals have the capability to manufacture gaskets making use of fast, accurate, automated cutting with the latest CAD/CAM technology. We have the capability to work to samples, drawings or CAD files (DWG files, DXF files etc).


The Artios Kongsberg Cutting System is designed for gasket production, but is suitable for most other 'soft' materials without the need for expensive tooling.

For prototype work or short and medium production runs the Artios Kongsberg computer-aided design and manufacturing system ensures quick and accurate cutting of gasket sheeting and many other materials. Shapes may be amended quickly and permanently stored digitally or on disk for future use.

Most designs can be cut twenty times faster than by hand with the added advantage that ​cutting dies and other ​tooling is no longer required.

Cost effective, just-in-time manufacture of complex gasket shapes is now a reality. But not just gaskets - this advanced method of cutting materials lends itself to a variety of other industries. Offering the latest and most powerful software and cutting technology, our investment in the Artios Kongsberg Cutting System further enhances the traditional service we offer to industry.


At Ashton Seals we consider ourselves to be specialists in Soft & Semi-Rigid Material Conversions rather than purely a Gasket manufacturer. For further information on Soft & Semi-Rigid Material Conversions please click here.
