    What Are Nitrile Cork Strips?

    Nitrile cork strips are commonly used as sealing or gasket strips, positioned between two surfaces to prevent leakage of liquids, gases, or air. They are also used as vibration and sound isolation strips, reducing unwanted noise in machinery or structural applications.

    Manufactured by combining natural cork granules with nitrile rubber, the resulting material is flexible, durable, and resistant to oil, fuel, hydrocarbons, and water. Nitrile cork strips are typically produced from sheets or rolls, with custom widths, lengths, and thicknesses available to suit individual project requirements.

    Applications of Nitrile Cork Strips

    Nitrile cork strips are widely used in industries that require chemical resistance, durability, and vibration or sound dampening, including:

    • Automotive: Sealing valve covers, fuel tanks, and sumps

    • Construction & Engineering: Surface protection, spacers, and industrial gaskets

    • Manufacturing & Industrial Machinery: Anti-vibration pads, covers, and sealing strips

    • Fuel & Oil Handling: Resistant to hydrocarbons and fuels

    • Electrical Applications: Transformers, switchgear, and inspection doors

    Different Grades of Cork Strips

    We offer nitrile cork in multiple grades to suit different requirements:

    • Nitrile-Bonded Cork: Combines cork’s natural flexibility with nitrile’s oil, fuel, and water resistance.

    • Neoprene-Bonded Cork: Adds UV, ozone, and weather resistance to natural cork properties.

    • Synthetic Rubber-Bonded Cork: Enhances cork for specialised chemical or fuel resistance applications.

    • Natural Cork: Maintains sound insulation, thermal properties, and sealing against air, dust, and water.

    Benefits of Nitrile Cork Strips

    • Sound & Vibration Suppression: Reduces noise and vibration in machinery.

    • Chemical Resistance: Protects against exposure to oil, fuel, and hydrocarbons.

    • Thermal Resistance: Performs effectively up to 120°C.

    • Flexible & Durable: Maintains integrity under compression and repeated use.

    • Customisable: Available in laminated, self-adhesive, or foil-backed finishes.

    • Natural & Sustainable Material: Eco-friendly and safe for industrial use.

    Advantages of Using Nitrile Cork Strips

    Nitrile cork strips are highly versatile and are trusted across automotive, manufacturing, and construction industries. Key advantages include:

    • Sealing & Protection: Ideal for surfaces that require protection against oils, fuels, and ozone exposure. 
    • Vibration & Sound Isolation: Minimises noise and vibration in mechanical components. 
    • Temperature & Chemical Resistance: Maintains performance in harsh environments. 
    • Custom Fabrication: Can be laminated, cut, or bonded with other materials for specific applications. 
    • Wide Industrial Use: Commonly used in sumps, inspection doors, valve covers, transformers, switchgear, and general-purpose sealing. 

    Nitrile Cork Strips from ASG provide a robust, oil-resistant, and flexible sealing solution suitable for a wide range of industrial and commercial applications.
