A yarn texturizing nozzle is disclosed which has two confronting sections that are separable along a separating plane projecting through and longitudinally of a yarn duct that extends through the nozzle and that is supplied with a pressurized fluid such as hot air. A piston within a cavity of one of the nozzle sections is biased by the pressure of fluid within such cavity into abutting engagement with the confronting surface of the other of the nozzle sections. The piston is so designed as to deform, under the force of such engagement, sufficiently as to conform to any unevenness of the confronting surface of the other nozzle section, and so as to minimize fluid leakage at the interface of the nozzle sections.
