A geothermal well head assembly that is so operatively associated with the production string of casing in a well bore that the string of casing may expand and contract longitudinally without placing any substantial strain on the assembly. The geothermal well head assembly is also of such structure that interior components thereof that may be damaged due to the abrasive action of high velocity pressurized geothermal fluid may be withdrawn from the assembly for maintenance or replacement without shutting down the geothermal well. Also the geothermal well head assembly is of such structure that it may be operated either manually or by pressurized fluid.
