Abstract
Supported face seal assemblies and related methods are disclosed. The supported face seal assemblies have spring energized seal element supported by a backing ring. When the two components are joined, they form an interlocking face seal assembly that is less prone to separate during installation and/or service. The methods disclosed include the steps of forming a spring energized sealing element with a convex outer surface, forming a backup or support ring with a concave inner surface, assembling the sealing element into the inner bore of the backup or support ring such that the concave inner surface accepts a portion of the convex outer surface and the sealing element is retained within the backup or support ring.
