Cork Gasket

Here at Advanced Seals & Gaskets, we offer a range of high quality gaskets, some of which are produced using different grades of cork including natural or cork bonded with neoprene, Nitrile, and synthetic rubber.   As our gaskets are produced in-house on state of the art machinery, we can manufacture bespoke items to match our customer's samples/drawings, from a simple picture frame gasket, to a more complex shape with cut-outs - our team can help.

Whether it’s a small sample batch or a multi-thousand run, we have a machine to quickly and accurately produce perfectly formed gaskets.  Our cork material is available in a range of standard manufactured thicknesses, however using our expertise, specialised splitting machinery, and in-house laminating service, we are able to offer other thicknesses or combinations of laminated material layers on request from which the gaskets can be cut.

Cork gaskets are most commonly used for sealing, vibration isolation, and sound deadening within applications such as electrical transformers and switchgear, valve covers, and fuel tank seals.  To discuss which grade of cork is best suited to your application, please give our sales team a call.

What are Cork Gaskets?

Gaskets when under compression, including those made of cork act as a seal between uneven surfaces and fill irregularities. Natural Cork gasket material consists of compressed cork grains with no other added chemicals other than a liquid binder known as ‘agglomeration’ to adhere the particles together. 

Bonded cork material is also manufactured using cork grains but is mixed with rubber granules (namely neoprene, nitrile, or synthetic rubber) which gives it greater flexibility and added properties for use in different applications and environments.   Cork material is flexible,  lightweight, waterproof, and practical, found in a vast range of applications including outdoor furniture and lighting, engineering, and automotive.

    Gaskets

    Here at Advanced Seals & Gaskets, we produce gaskets in many materials such as Neoprene, EPDM, Solid Rubbers, Felt, Plastics, Polyethylene, PVC, Silicone, and Sponge Rubber as well as many more materials.  Our gaskets are used by our customers in a wide array of applications such as automobiles, Aerospace, Manufacturing, Machinery, Production, and Safety Equipment.

    We produce these gaskets to specified drawings in house using our state of the art machinery such as our oscillating Knife and atom Press. For more information please get in touch.

    Why use Cork Gaskets?

    Cork gaskets can be made from natural cork or Neoprene, Nitrile, and Synthetic Bonded Cork. Cork Gaskets have many desirable qualities mainly thermal insulation, noise and vibration absorption properties,   and sealing against air, oil, and chemical leaks. Cork gaskets are used in many engineering industries where they are used underneath compressors and heavy plant machinery to control and reduce noise and vibration. 

    Cork is chemically inert, resistant to fungus and mould growth, flame retardant, anti-static, flexible, and durable.  Cork material is easy to work with, it is an easy material to cut to shape, it holds adhesive well, and due to its flexible nature cork gaskets fit and adhere to most surfaces.

    Benefits of Cork Gaskets

    • Sound Suppression & Anti-vibration
    • Thermal Properties
    • Bonded with Other Materials Based on Application
    • Oils Resistance
    • Flame retardant
    • Flexible

    Different Grades

    Advanced Seals & Gaskets Ltd can offer different grades of cork gaskets for use within various industries each with its own unique characteristics, depending upon the material with which it is blended.  

    Natural Cork –  a combination of grains of cork and a liquid binder.  Natural Cork is relatively cheap compared to sponge and rubber and can be used as air/dust/water seals, in thermal insulation, acoustic, and anti-vibration applications.

    Resin bonded cork –  a lightweight, flexible cork, produced using cork granules bound together using a synthetic resin.  This grade of cork is resilient to certain acids and is often used in water retaining applications.

    Nitrile bonded cork – manufactured using a combination of cork and nitrile rubber granules, giving a speckled appearance.  Gaskets made from this material can be used where oil and fuel resistance is required, or where high temperature resistance is required, industries include automotive and general engineering.

    Neoprene bonded cork – Neoprene bonded cork is a combination of cork and neoprene rubber granules, bound together.  This grade has the same speckled appearance as the Nitrile Bonded cork, but with different properties, with the addition of the Neoprene rubber, the cork is suited to sealing at higher temperatures and resistant to weathering and oil.  Neoprene Bonded Cork gaskets are suited to oil, engineering, electrical, anti-vibration, and soundproofing applications.

    Advantages of Using Cork Gaskets

    The various grades of cork come with countless advantages and properties that are ideal for many industries.  Not only is cork aesthetically appealing, but it is also non-toxic,  water-resistant, resistant to mould and damp, extremely fireproof, and has excellent sound, vibration and thermal properties.  Cork gaskets can be supplied in specifically cut shapes sizes, split down or laminated together to produce non-standard thicknesses, laminated to other materials for added properties.  Cork gaskets can be easily produced using one of our many presses, kiss-cut machines, and even our oscillating knife for larger/thicker gaskets.
