Design Guide: Information for the Rubber Seal Design Process

Support for Designing Seals, Gaskets and Weather Stripping

This rubber seal and gasket design guide is intended to give design engineers the basic facts needed to begin the process of designing effective rubber seals, gaskets and weather stripping. It is not intended to provide every piece of information available on the process or extrusion—the amount of information available is simply too great. However, it can serve as a starting point and gives engineers the necessary information to better understand what they will need to consider during the design process.
