Abstract: Seals and apparatuses incorporating seals are provided. In one embodiment an apparatus is provided including two relatively machine elements, the first machine (204) element having a gland (202) formed therein. The gland has a first axial wall, a second axial wall and a radial wall disposed therebetween. The apparatus further includes a sealing ring (208) disposed at least partially within the gland, the sealing ring having a radially inner face (212) in contact with the first machine elements, a radially outer face (217), a first axial face (216), a second axial face (214) spaced apart from the first axial face, an angled face (218) extending between the first axial face and the radially outer face, and at least one channel (220) formed in the angled face and extending from the first axial face to the radially outer face. A loading ring (210) is configured to maintain contact with the angled face of the sealing ring, the first axial wall of the gland and the radial wall of the gland.
