A coupling seal assembly is described for directing a pressurized abrasive fluid between a non-rotating conduit member and a rotating second conduit member. The seal assembly includes a first ceramic floating seal member secured to the non- rotating conduit member and a second ceramic seal member secured to the rotating conduit member. Enhanced service life of the seal assembly under high pressures and high rotary speeds is achieved.
