Dual durometer seals 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 product color schemes or the use of pressure-sensitive adhesives (PSAs).

By fabricating dual durometer rubber into a single part, a product such as window seal can have areas with different physical properties to meet application requirements. With window channels, the harder window rubber attaches to the window frame and the softer window rubber faces the glass window. Durometer is not limited to window seals, however, and is used with both sponge and solid profiles.
