Natural Sponge Rubber Washers
Natural sponge rubber is a lightweight, open-cell material commonly manufactured in thicknesses ranging from 3mm to 25mm. Natural sponge rubber washers offer excellent anti-vibration and acoustic absorption properties, along with durability and flexibility. Advanced manufacturing technology allows us to add self-adhesive backings, films, or laminate layers to create bespoke products tailored to specific applications. Using state-of-the-art machinery, including atoms, autos, kiss-cutting presses, and CNC/oscillating knife equipment, we produce washers efficiently while maintaining high quality and minimising lead times.
At Advanced Seals & Gaskets Ltd, all conversions are completed on-site, providing total quality control at every stage of production. Whether producing a one-off sample or a high-volume batch, we work closely with customers to deliver fully customised solutions. Our highly trained workforce ensures that every product meets exact specifications, providing reliable, long-lasting performance.
Natural sponge rubber is also available in other forms, including:
- Seals
- Pads
- Gaskets

What Are Natural Sponge Rubber Washers?
A washer is a flat ring with an outer diameter (OD) and an inner diameter (ID) that is cut from a sheet of material and placed between two surfaces. Washers act as spacers, seals, or to distribute pressure when fastening nuts and bolts evenly.
Natural sponge rubber washers are typically supplied in rolls and can be cut to meet a wide range of specifications. Unlike closed-cell foams, natural sponge rubber allows fluid circulation when required while maintaining excellent compression and recovery due to its multi-patterned skin.
Why Use Natural Sponge Rubber Washers?
Natural sponge rubber washers are available in a variety of grades, lengths, and thicknesses, ready for dispatch. Alternatively, they can be custom-cut and shaped to meet individual requirements.
These washers are frequently used to seal against dust, air, water, and other contaminants on uneven surfaces. Their superior anti-vibration and acoustic absorption properties make them ideal for protective packaging, sound-reducing floor strips, and other industrial or commercial applications.

Advantages of Using Natural Sponge Rubber Washers
Natural sponge rubber washers combine a soft, flexible feel with an open-cell structure, allowing moisture to circulate slowly while maintaining durability.
Available in multiple grades and thicknesses, these washers are ideal for sealing uneven surfaces, complex shapes, or delicate components. Their superior compression recovery and vibration absorption make them suitable for flooring, packaging, machinery, and other applications requiring reliable cushioning and protection.
