Dual Durometer Rubber Seals

Dual durometer rubber products are extrusions with different areas of hardness. Typically, the harder rubber is used for attachment while the softer rubber is used for sealing. Sometimes, different materials are used because of design considerations such as product color schemes or the use of pressure-sensitive adhesives. This rubber seal strip has solid and sponge advantages. It provides more options to fill the space of equipment.
