Abstract:
High pressure seals for pressure control fittings are disclosed, where such pressure control fittings are located at a wellhead, for example. Embodiments of cam lock seals, a spring-driven ball race seal and wedge seals are disclosed.

Claim (Index 6):
A pressure-retaining seal, comprising:\n a generally tubular adapter having first and second adapter ends, the first adapter end configured to mate with pressure-retaining equipment, the second adapter end providing an external adapter rib, the adapter rib providing an adapter sloped surface formed thereon; a generally tubular pressure seal assembly having first and second assembly ends and a longitudinal centerline, the centerline defining (a) an axial direction parallel to the centerline and (b) radial directions perpendicular to the centerline; the first assembly end providing a seal receptacle for receiving the second adapter end, the second adapter end and the seal receptacle further each providing cooperating abutment surfaces, the cooperating abutment surfaces forming a pressure seal between the second adapter end and the seal receptacle when the second adapter end is received into the seal receptacle; and a wedge assembly, the wedge assembly configured to engage both the second adapter end and the first assembly end when the second adapter end is received into the seal receptacle, the wedge assembly, including at least one wedge surface for engagement with the adapter sloped surface; wherein, when the second adapter end is received into the seal receptacle, constriction of the wedge assembly towards the centerline engages the at least one wedge surface onto the adapter sloped surface so as to compress the cooperating abutment surfaces together.
