One of Advanced Seals & Gaskets' more popular products is washers. We manufacture 1000’s gaskets daily in our newly renovated facilities using a range of materials which include Anti-Vibration cork. All our washers are manufactured in-house using a combination of a skilled workforce and high-spec machinery.
Using either our oscillating knife or one of our many presses, depending upon size, thickness and quantity required, our range of machinery means we can manufacture cork washers to match your specified dimensions in any quantity quickly and efficiently, which in return passes on a quality product and a cost-saving.
Cork washers are produced using either samples, drawings or dimensions provided by customers, which would detail the Outer Diameter (OD), Internal Diameter (ID) and Thickness. Our washers can be manufactured in a plain or self-adhesive or foil-faced finish, as singular cut parts or kiss cut on a roll.
What are Anti-Viabration Cork Washers?
A ‘washer’ is a flattened ring of material that is placed between 2 surfaces in order to reduce friction and prevent unsteadiness, creating a level surface for nuts, bolts and other fixings to rest on, improving the fit for fixings and can be used as a water or air tight seal. Anti-vibration cork washers are highly compressible and suitable for low to medium bolt pressure, with excellent durability and flexibility.
All cork materials can be used as insulation against vibration, however, cork bonding with synthetic rubber such as EPDM, neoprene, Nitrile or SBR increases the natural corks flexibility and gives it resistance towards oils, petrol, acids and higher temperatures.

Why use Anti-Viabration Cork Washers?
Anti-vibration cork washers offer a multitude of solutions including sound absorption, sealing against oil, air or chemical leaks and protection for moving parts with machinery and equipment from abrasive damage.
Anti-vibration cork washers can be found used in heavy industrial machinery, railway production, automotive, industrial refrigeration, generators and acoustic suspension buildings where they help dampen or eliminate the noise and vibrations that are generated from large machinery, these vibrations, if not treated with anti-vibration cork gaskets, can cause damage to building foundations, users hearing and the machine itself which can lead to further dangerous issues.
The Advantages of Using Anti-Viabration Cork Washers
There are many advantages to using anti-vibration cork as a gasket material, such as noise and vibration control, thermal insulation, doesn’t absorb water or allow for the growth of mould and is naturally flame retardant. Anti-vibration cork washers are often used for the reduction of noise and vibration, usually produced by heavy machinery or equipment.
The high level of vibration or shaking caused by such machinery not only causes further damage to surrounding foundations and creates an unsafe environment for workers, but can also create excess noise leading to hearing impairment.
Cork as a material is safe to work with as it is non-toxic and doesn’t shed like some foams and fibrous materials meaning it will not cause irritations to those with allergies.
Benefits of Anti-Viabration Cork Washers
- Sound Suppression
- Thermal Properties
- Bonded with other materials for use with different applications
- Oils, chemical, fuel & acid resistance (varies between grades of cork)
- Vibration dampening
- Durable with abrasion and friction resistance
Different Grades of Cork Washer Available
Washers can be manufactured using a range of different cork materials, all of which can offer vibration dampening benefits, but when bonded with rubber, can offer a number of additional properties, these include:
Neoprene bonded cork is suited to sealing at higher temperatures and resistant to weathering and oil. Neoprene Bonded cork is suited to oil, engineering, electrical, anti-vibration and soundproofing 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.
Natural Cork – consists of grains of cork with no other added chemicals other than a liquid binder known as ‘agglomeration’ to adhere the particles together. Natural Cork is relatively cheap compared to sponge and rubber and can be used as a simple coaster, air/dust/water seals, thermal insulation, acoustic and anti-vibration applications.
Synthetic Cork (SBR) - a combination of synthetic rubber granules and natural cork creates a highly compressible material suitable for low and medium bolt pressure. The rubber used in this grade provides good flexibility and resilience and improved resistance to oil and fuel. This material is often used for automotive and industrial gaskets and within construction or plant rooms for noise and vibration reduction.
