Abstract

A coating system applicator component, e.g. a valve or bell cup, which may be used to be wetted and/or flown through at least in some sections by a coating agent, is provided. The applicator component includes a cylindrical holding part configured to releasably couple a mount of the coating system, as well as an applicator thread on the holding part. The applicator thread includes first and second applicator flank surfaces each obliquely oriented to a radial direction of the holding part, the first and second applicator flank surfaces being asymmetric about the radial direction of the holding part. The first and second applicator flank surfaces are configured to be parallel to and interface with first and second mount flank surfaces of a thread of the mount, respectively, upon a coaxial, threaded engagement between the holding part and the mount.
