A sealing assembly is disclosed for creating a seal between first and second mating members or components. The sealing assembly basically includes a seal retainer with one or more annular seals coupled thereto. The seal retainer including a substantially flat body portion lying in a plane and with at least one resilient retaining element integrally formed with said body portion as a one-piece, unitary member for engaging the seal(s) to retain the seal(s) thereto. The seal retainer has an indicator formed on its body portion to indicate if the seal retainer has been used. In the preferred embodiment the indicator is a raised protrusion which normally extends outwardly from the plane of body portion of the seal retainer. Once the seal retainer is used, the raised protrusion of the indicator is deformed inwardly into the plane of the body portion of the seal retainer.
