A sanitary fixture is provided having an upstream end and a downstream end, the sanitary fixture includes a mounting housing having a thread which is matingly engagable with a thread provided on a water outlet of a sanitary outlet fitting. The mounting housing has a downstream housing end side with flow-through holes. At least one insertion part can be inserted into the mounting housing as far as an insertion stop. The fixture includes an aerated jet regulator which is configured such that a circumferential wall of the mounting housing includes at least one aeration duct at least in a subregion of at least a double-walled configuration. The at least one aeration duct, which is arranged towards the downstream housing end side, opens out in at least one aeration opening leading into a housing interior of the mounting housing.

A pressure washer spray gun includes a spray gun body configured to be fluidly coupled to a source of pressurized water, a chemical container coupled to the spray gun body, wherein the chemical container is configured to contain liquid chemical, a venturi including a converging section, a throat, and a diverging section, wherein the venturi is coupled to the body, and wherein the chemical container is fluidly coupled to the throat, an air inlet port formed in the diverging section and configured to fluidly couple the diverging section to a source of air, and multiple nozzles, wherein each nozzle has a different orifice diameter, and wherein only one nozzle at a time can be selected to provide a fluid output from the spray gun.

A ball joint connector is provided for linking a showerhead to a water supply pipe. The connector has an internal venturi that draws air into the connector to aerate water being provided to the showerhead. A flow control member is disposed in a fluid pathway connected to the venturi, preventing spraying or leaking out of the air inlet, while reducing noise associated with the air induction.

Wands are used as parts of cleaning systems to conduct cleaning agents into gas turbine engine cores. Wands according to the present disclosure include inlet assemblies adapted to connect to cleaning agents, dispensers adapted to discharge cleaners into gas turbine engines, and conduits that extend from the inlet assemblies to the dispensers.
