The annular seal assembly and seal arrangements including the seal assembly disclosed are useful in high pressure pumps and compressors and the like that include a cylinder having annular grooves therein for receiving the seal arrangements and having a plunger reciprocating in the cylinder through the seal arrangements. The seal assembly includes segmented tangent and radial ring assemblies. Each of the segments in the tangent ring assembly includes tangentially disposed end surfaces that are arranged to sealingly and slidingly engage the adjacent tangentially disposed end surfaces. The radial ring assembly is constructed from a plurality of arcuate segments having an outer periphery sized to be closely fitted into a counterbore formed in one face of the tangent ring assembly. With the radial and tangential rings assembled, the forces exerted by the high pressure fluid on the tangent ring assembly are transferred to the radial ring assembly, providing better lubrication and longer seal life. The disclosed seal arrangements promote better operation and better seal life due to the distribution of the pressure load over several seals.
