Generally speaking, there are two major considerations that determine the seal profile for an application: geometry and environment. Consider the generic rubber seals profile above. Each of the labeled dimensions is defined by touching the cursor to the label.
Defining the geometry of your application means describing what you intend for the seal to do mechanically in the application, and how you envision the seal's placement in the application. In other words, we need to know how much room there is in the application to mount the seal, and how far the seal will need to "stroke" to meet the striking surface.
A sketch/drawing of your application is most helpful for Seal Master Engineers in determining the best inflatable seal approach for your application. Consider the generic seal profile above. Each of the labeled dimensions is defined by touching the cursor to the label. To determine if your application requires the seal to function in the axial, radial-in, or radial-out direction, feel free to revisit "Seal Master Inflatable Seal Basic Geometry"
