Our cork gaskets are designed for durability, flexibility, and excellent sealing properties, making them a trusted choice for engineers and manufacturers alike.
What Are Cork Gaskets?
Cork gaskets are sealing components placed between two surfaces to prevent leakage of air, liquids, or gases. They work by filling surface irregularities when compressed, forming a tight, reliable seal.
Cork gaskets are manufactured in two main types:
- Natural Cork: Comprised of compressed cork grains bonded with a liquid binder, natural cork offers flexibility, lightweight properties, and excellent sealing performance.
- Bonded Cork: Combines cork granules with rubber compounds such as neoprene, nitrile, or synthetic rubber to improve flexibility, chemical resistance, and thermal performance.
Cork is inherently flexible, durable, waterproof, and resistant to mold, making it suitable for applications requiring long-term reliability under varying environmental conditions.

Key Characteristics of Cork Gaskets
- Colour: Natural (black speckles for bonded cork)
- Bonded Materials: Nitrile, Neoprene, Natural, Synthetic Rubber
- Density: 0.56 – 0.70 g/cm³
- Resistances: Oils, Fuels (nitrile bonded), Sound Suppression, Water Resistance
- Temperature Range: -20°C to +120°C
- Thickness: 0.8mm – 25mm (can be laminated for greater thickness)
Cork gaskets can be supplied in sheets or pre-cut custom shapes. Laminated cork gaskets allow for non-standard thicknesses or enhanced performance, increasing versatility for a wide range of applications. Full technical datasheets are available on request or via our online portal.
Why Use Cork Gaskets?
Cork gaskets are highly versatile, combining mechanical flexibility, chemical resistance, and thermal insulation. They are commonly used in industries where vibration damping, sound suppression, and reliable sealing are critical.
Key advantages include:
- Sound and Vibration Absorption: Cork naturally dampens vibrations and reduces noise, making it ideal for heavy machinery, compressors, and engines.
- Thermal Insulation: Provides excellent resistance to temperature fluctuations.
- Chemical Resistance: Certain bonded cork gaskets, like nitrile bonded cork, resist oils, fuels, and other chemicals.
- Flexibility: Cork conforms to uneven surfaces, ensuring a secure seal.
- Durability: Resistant to mold, dampness, and fire, making it suitable for long-term use in demanding environments.
Cork gaskets are easy to cut, shape, and laminate, allowing for tailored solutions that fit precisely within the required application.
