Sponge Gaskets can be made from a variety of sponge and foam materials, many of which we hold in stock. These gaskets for typically used when moisture, dust, powder, air and gas retention are required. The two types are Open Cell and Closed Cell Sponges. Open cell sponge has connecting cavities which make the sponge more compressible. Closed Cell sponges are void of connected cavities, which makes them ideal for applications where water exclusion and sound and gas retention are paramount.
