Natural Cork Washers

Premium Natural Cork Washers for Sealing, Insulation, and Anti-Vibration Applications

At Advanced Seals & Gaskets Ltd, we specialise in the supply and in-house conversion of natural cork materials into high-quality washers. Available in standard sheets and rolls, our natural cork can be cut, laminated, or finished with self-adhesive backing to meet a variety of industrial, automotive, and engineering requirements.

Our on-site production capabilities ensure precision and consistency. Using customer-provided drawings or specifications for outer diameter (OD), inner diameter (ID), and thickness, we can manufacture both one-off samples and large production runs with equal efficiency. Depending on quantity and complexity, we utilise presses, kiss-cut machines, or CNC cutting equipment to produce cork washers tailored to exact needs.

What Are Natural Cork Washers?

Natural cork washers are made by compressing cork grains with a liquid binder, resulting in an eco-friendly, lightweight, and flexible material. Cork is a cost-effective alternative to sponge and rubber, offering excellent sealing, insulation, and vibration absorption properties.

Washers act as flattened rings that distribute load, reduce friction, and provide a smooth, level surface for fastenings. Cork washers are ideal for creating seals that resist air, dust, water, and moisture, while also serving as thermal, acoustic, and vibration dampers.

Our natural cork washers can be supplied plain, laminated with other materials, or adhesive-backed, making them versatile for prototyping, custom applications, and high-volume production.

    Why Use Natural Cork Washers?

    Natural cork washers are highly valued across multiple industries for their strength, flexibility, and resilience under pressure. Key applications include:

    • Automotive industry: Sealing components, vibration reduction, noise suppression

    • Heavy plant and machinery: Pumps, compressors, and moving parts

    • Industrial equipment: Anti-vibration pads and insulation

    • Construction: Water, air, and dust seals for outdoor applications

    Natural cork washers offer several advantages over rubber and sponge alternatives:

    • Excellent thermal insulation – protecting components from temperature extremes

    • Sound and vibration damping – reducing noise and equipment wear

    • Chemical and odor resistance – suitable for harsh environments

    • Water and air impermeability – reliable sealing performance

    • Eco-friendly and non-toxic – safe for industrial and consumer applications

    Benefits of Natural Cork Washers

    • Sound suppression for quieter operation of machinery and vehicles

    • Thermal properties that protect against heat and cold

    • Anti-vibration performance for improved stability and reduced wear

    • Weather-resistant and durable in outdoor and high-moisture environments

    • Easy to cut, convert, and laminate to meet specific requirements

    • Non-toxic and mold-resistant

    • Aesthetically appealing compared to some rubber alternatives

    These benefits make natural cork washers a versatile choice for engineers, manufacturers, and designers seeking reliable, durable, and cost-effective solutions.

    Different Grades of Cork Washers

    While natural cork is ideal for many general applications, other cork grades provide specialized properties for more demanding environments:

    • Neoprene Bonded Cork: Combines cork with neoprene rubber granules, offering higher temperature resistance, oil resistance, and enhanced durability. Ideal for oil, engineering, electrical, anti-vibration, and soundproofing applications.

    • Resin-Bonded Cork: Lightweight and flexible, made from cork granules bound with synthetic resin. It is resilient to certain acids and suitable for water-retaining applications.

    • Nitrile Bonded Cork: Combines cork with nitrile rubber granules, producing a speckled appearance. Offers excellent resistance to oils, fuels, and high temperatures, making it perfect for automotive and general engineering industries.

    By selecting the appropriate cork grade, customers can tailor washers to specific performance requirements, from chemical resistance to vibration damping and thermal insulation.

    Applications of Natural Cork Washers

    Natural cork washers are widely used in:

    • Automotive components – engine seals, bushings, and vibration dampers

    • Machinery and industrial equipment – pumps, compressors, and hydraulic systems

    • Electrical equipment – insulation and anti-vibration washers

    • Construction and building – water, air, and dust seals for doors, windows, and outdoor fixtures

    • Prototyping and custom engineering – adaptable for one-off or bespoke projects

    Their versatility, cost-effectiveness, and environmentally friendly composition make cork washers a trusted choice for engineers and manufacturers worldwide.
