Abstract
A sealing system for establishing real time sealing between two flange members is provided. The sealing system includes a seal assembly disposed between the flange members. The seal assembly includes an o-ring seal component held between an outer seal component and an inner seal component. A clamp body including a first clamp arm and a second clamp arm receive the flange members and the seal assembly positioned between the flange members. A coupling device of the sealing system is used to apply torque to clamp arms to draw them each other resulting biasing the flange member toward each other to establish sealing. Each of the clamp arms includes at least one window opening to expose a portion of outer seal component that includes an indicator configured for displaying an identification feature of the o-ring seal component of the sealing assembly.
