Spring energized seal assemblies configured for use in static or dynamic application and methods of using and making same are provided. The seal assemblies can each have a sealing component and optionally a backup ring or a locking ring or both. An annular spring can be used with a spring groove of either the backup ring or the locking to facilitate assembling of the mentioned components of a seal assembly onto each other and the entire seal assembly into a seal cavity of a housing.

Seal assemblies and related methods

Seal assemblies and methods that include a seal lip that comprises an extended portion with generally constant cross-sectional width for low and generally constant friction during wear are described. The seal lip is loaded against a dynamic member by the aid of a spring energizer. The extended portion of the seal lip maintains constant torque resistance during movement of the dynamic member.
