Abstract
A pressurized fluid delivery apparatus, such as a pressure washer or sprayer, includes a pump for providing a pressurized fluid, a conduit fluidly connected with the pump to receive the pressurized fluid, a fluid accessory fluidly connected with the conduit to receive the pressurized fluid from the conduit, and a quick-disconnect assembly selectively fluidly connecting the fluid accessory and the conduit. The quick-disconnect assembly includes a male fitting coupled to one of the fluid accessory and the conduit. The male fitting includes a male component and a non-circular outer surface. The quick-disconnect assembly also includes a female fitting coupled to the other of the fluid accessory and the conduit. The female fitting includes a female component having an opening for receiving the male component and a non-circular inner surface coupled to the non-circular outer surface to prevent rotation between the male fitting and the female fitting.
