Zusammenfassung:	A sealing apparatus for sealing against an inner surface of a tubular in a wellbore. The apparatus comprises a mandrel (110) having a first groove (130, 250) and a second groove (130, 250) and a seal ring (125) disposed in the first groove. The seal ring has one or more anti extrusion bands (141, 142) embedded within the seal ring (125), and the seal (125) ring is configured to engage the inner surface of the tubular. The apparatus further comprises a wiper ring (250) disposed in the second groove, and an o-ring (245). The wiper ring (250) is configured to wipe the inner surface of the tubular prior to the seal ring engaging the inner surface of the tubular. The o-ring (245) is disposed in the second groove (130, 250) between the wiper ring (250) and a bottom wall of the second groove (130, 250).
