    What are natural Sponge Rubber Washers?

    A washer is a flat ring with an outer diameter (OD) and inner diameter (ID) measurement that has been cut from a sheet of material and placed between two surfaces to create a level surface, act as a spacer or seal, or spread pressure when tightened.

    Supplied as standard in rolls, natural sponge rubber can be cut and shaped into washers that meet a range of specifications. Unlike its closed-cell counterparts, natural sponge rubber facilitates the circulation of fluids in applications requiring it, while its multi-patterned skin ensures excellent compression and recovery properties.
