In April 2003 Ashton Seals position was strengthened through the acquisition of the gasket cutting company Clough (Croydon) Ltd., a specialist in the production of high quality gaskets, and the supply of sheet jointing, all of which complement the existing Ashton Seals portfolio.

At the start of 2004 Clough (Croydon) was fully integrated into Ashton Seals becoming the Ashton Seals Gasket Division, operating from our premises in Barnsley.

Clough (Croydon) has brought to Ashton Seals over 70 years experience in gasket manufacture and through using the latest CAD/CAM technology Ashton Seals is now able to provide a competitive and responsive service in all materials.

A particularly close relationship exists with Klinger Ltd., and a full gasket service exists for the supply of cut products manufactured in Klingersil and Topchem sheet material. Graphite and metal gasket products also feature within the wide product range.

The expertise and experience that Ashton Seals are now able to offer makes us unique within the industry. Whether your requirement is for a one-off prototype or a multi-thousand run we have the ability to meet your requirement both quickly and competitively.

CUT GASKETS & SHEET

Ashton Seals stock a complete and versatile range of material, including compressed non-asbestos fibre (CNAF), together with commercial rubber, neoprene, nitrile, EPDM, butyl, silicone, viton® and polyurethane 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.

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

Simply advise:-
· 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.

Special Gaskets

Should press cutting not be practical or economical we have the ability and experience to produce hand-made joints to any shape or size.

Cork

The durability and versatility of cork has made it one of the most popular materials for sealing applications. Being a natural product, it possesses many advantages. It can be compounded with a variety of raw materials to provide a comprehensive range of sealing products.

The merits of various synthetic rubber compounds such as neoprene, nitrile and silicone are well known. By blending carefully selected high quality cork granules with these polymers, finished products can be provided which combine all the advantages of rubber:-

High tensile strength, resistance to many fluids, ability to withstand extremes of temperature - with the natural properties of cork - high compression, good recovery and low load sealing.

Neoprene Bonded Cork

It is by far the most versatile and popular of the whole range of cork sheetings. Widely used in the petrochemical industry, in marine and general engineering, on large internal combustion engines, compressors, refrigerator systems, transformers and on any similar application where efficient sealing is required under vibratory or fluctuating conditions.

Nitrile Bonded Cork

Compounded especially for use with automatic, high octane and aviation fuels (kerosene), the range of materials under this heading can also be varied in formula to provide optimum sealing with controlled swell under the most arduous conditions.

Gasket Paper

Made from vegetable fibre, specially impregnated to provide high resistance to petroleum derivatives, solvents and lubricating oils, and suitable for operating at temperatures up to 120°C (250°F). It is available in roll form 1 metre wide and in thicknesses from .15mm to 3mm. A complete gasket cutting service is available in this material.

Plastics

We manufacture gaskets and machined components from many of the different engineering plastics - e.g. polythene, polypropylene, nylon, PVC and fluorocarbons such as viton® and PTFE.

PTFE

PTFE provides excellent resistance to an exceptionally wide range of aggressive substances. Additionally it is chemically inert, increasing its suitability for applications sensitive to external contamination.

Extruded and Moulded Rod and Tube

To BS 4271, BS 3873 and BS 5130. Extruded rod is available in sizes from 4.8mm diameter to 63.5mm diameter and in 1m or 2m lengths. Moulded rod is available in 12" lengths from 54mm diameter to 305mm diameter.

Whatever the application we can supply an efficient solution to meet your requirements.

PTFE Sheeting

To BS 3784. Available in thicknesses from 0.8mm to 51mm and in sheet sizes from 305mm x 305mm to 1220mm x 1220mm. Chemically or mechanically etched sheet and strip is available where bonding to other components or structures is required. Thinner gauge sheeting is also available.

Virgin, Expanded or Filled PTFE

• Virgin PTFE grades are used for Gaskets in the food & pharmaceutical industries
• Expanded PTFE grades are used for damaged flange faces and glass or plastic flanges
• Filled PTFE grades are used where specific physical or electrical properties are required.

PTFE Envelope/Rubber Insert Gaskets

Standard Rubber joints can be provided with an envelope of pure PTFE to protect the exposed joint edge from corrosive attack, or for applications where hygiene conditions are essential. In addition we stock a wide range of PTFE envelopes to suit standard pipe flanges and special envelopes can be fabricated to almost any given size or insert.

RUBBER

We maintain a comprehensive range of rubber sheeting in a variety of thicknesses from which the vast majority of applications can be satisfied.

Rubber sheeting and strip can be supplied in many qualities and cut to suit your requirements. Our technical sales staff will be pleased to advise you on the most economical means of meeting your needs.

Sponge Rubber gaskets and Strip can be supplied is available where a joint is required to be highly compressible under light flange loading. We can produce a wide variety of gaskets, joints and strip in many grades of sponge rubber, with or without a pressure-sensitive adhesive packing.

We provide an efficient service for extruded, moulded and machined components, and will be pleased to discuss your specific requirements.

Rubber Matting

Since the origination of the standard for electrical matting in 1976, BS921 Safety Matting has been widely used in a variety of switchboard, high voltage, test bench & repair shop applications. We supply 15Kv (BS921), in 3 standard roll widths 914mm, 1m & 1.22m) 11Kv matting is also available in these same size.
