Abstract
Abstract A spray nozzle assembly, especially for spraying liquid manure, has a nozzle body which can be inserted in and fastened to a pipe stud by means of a union suitable for dye coding so that the nozzle can be easily identified. The nozzle body is surrounded by a circumferential metal sealing disk pressed into the union with the rim of the disk cutting into the inner wall of the union during the pressing step.
