Nitrile Cork Washers

Nitrile Cork Washers

Advanced Seals & Gaskets produce high-quality washers from an array of materials including Nitrile Bonded Cork. Our washers are manufactured in-house using a combination of a skilled workforce and high spec machinery in practically any size and quantity, with a plain or self-adhesive finish to one or both faces and in a choice of individually cut parts or kiss cut in roll for quick and easy application.

Nitrile bonded cork washers are based on either samples, dimensions, or drawings provided by our customers which would outline the Outer Diameter (OD), Internal Diameter (ID), and thickness. 

Nitrile bonded cork washers are often used by customers within the automotive, construction, manufacturing, engineering, and fuel industries as the material are oil, fuel, hydrocarbon, and weather resistant. 

What are Nitrile Bonded Cork Washers?

Washers are a flattened ‘ring’ of material that is placed between 2 surfaces to reduce friction and prevent unsteadiness, it creates a smooth, level surface for nuts/bolts to rest on or for a better bit for nuts/bolts and, can be used as an air/watertight seal. 

Nitrile bonded cork is made from an amalgamation of cork and nitrile rubber granules bound together, creating a brown colored material with black pigments scattered throughout.  The nitrile adds properties to the cork such as resistance to oil, fuel, hydrocarbons, and water, with a durable physicality.  This material is manufactured in sheet and roll form from which washers can be cut.

    Washers can be used as a gap filler, seal, cushion or spacer to reduce friction and wear and tear between surfaces and fittings.  We manufacture washers using an extensive range of materials such as EPDM, neoprene, silicone, solid rubbers, sponge, plastics, polyethylene, PVC, Polyester, cork, textiles and many more, using specialist machinery including presses and kiss cut machines.  Our lamination service also allows us to supply washers in greater thicknesses, with a choice of self-adhesives or foil faces.

    Why use Nitrile Bonded Cork Washers

    Cork washers can be found utilised in many industries, the choice of material and grade is determined by factors such as environment, cost, and the application itself.   Nitrile bonded cork material has a vast range of desirable properties including anti-vibration, weathering, water, oil, and solvent resistance.  It is flexible and a relatively cheap material choice which is also good for use with petrol and will seal at temperatures up to 120°C. 

    As our nitrile bonded cork washers are manufactured in-house, we have the capabilities to manufacture them with a range of finishes, adhesive tapes or laminated to any of the other materials in our catalogue, combining properties and creating a unique and robust product.  Our Nitrile bonded cork washers are highly utilized in the automotive, engineering, construction, industrial, and manufacturing industries. 

    Different Grades

    Cork gaskets can be produced in various other grades, such as natural cork, or bonded with other materials other than nitrile such as neoprene and synthetic rubber.

    Natural cork holds thermal and sound suppressing properties, it also provides an excellent seal against air/dust and water.

    Neoprene bonded cork has the core properties of cork while adding the base properties of neoprene such as the high water and weather resistant qualities, ensuring the material continues to perform as an excellent seal when exposed to UV rays and ozone.

    Synthetic bonded cork is highly compressible and offers flexibility, oil/fuel resistance, and anti-vibration properties.
