Our sponge seals are ideal for various marine, automotive and industrial applications. Manufactured in a wide variety of shapes and sizes, these sections provide a solution to most sealing problems. Sponge seals are available in numerous forms, including extruded profiles or cut strip and sheet. These products serve different purposes and offer different levels of compression and recovery. All of these products are manufactured from closed-cell sponge rubber materials so will not absorb water.
Extruded profiles have an external skin and are often manufactured with a hollow centre or external fin to aid compression under minimal force. We also supply an extensive range of sponge strip cut from large sheets of sponge rubber. As these sections do not feature a central hole, they are marginally firmer than similar sized extruded profiles. Most sponge sections, extruded or cut, can be supplied with a self-adhesive backing to simplify the installation process.
As sponge seals are manufactured from soft compressible materials, we recommend that they are compressed by up to 30%. For example, if you have a 10mm gap we recommend using a sponge seal that is approximately 15mm high. When compressed this will create a good watertight seal and minimise the chance of damaging the section with excessive force.
