Abstract: A split mechanical composite seal assembly for providing a seal between a rotating shaft and a static surface. The split mechanical composite seal assembly includes first and second axially adjacent annular seal elements. The first and second seal elements each include a sealing edge contacting the shaft to provide a respective seal between the first and second seal element and the shaft. A static housing receives the first and second seal elements and engages the static surface to provide a static stationary seal, while concomitantly providing a flex region that engages the seal elements to form a dynamic seal therewith. A holder assembly receives one seal element and may include a double-angled lead-in to facilitate installation of the seal element. The holder assembly may include a detent groove for receiving and retaining an O-ring disposed about the seal element. The static housing may comprise two mating segments having overlapping surfaces.
