ABSTRACT:
A power operated pressure washer having a high pressure liquid supply hose with an inlet fitting formed with an axial stem having a central liquid passageway that can be connected to a pressure washer outlet fitting by a threaded retaining ring. As a feature of this invention, the retaining ring can be unscrewed from the pressure washer outlet for permitting the dissipation and venting of high pressure buildup within the hose while the retaining ring safely retains the hose fitting on the outlet. In one embodiment, the stem has a pair of axially spaced annular sealing members adaptable for sealing engagement with relatively smaller and larger size pressure washer outlets and the stems is formed with a transverse passageway for venting liquid from the central stem passageway around one of the sealing members, as an incident to unscrewing of the retaining ring, while the other sealing member remains in sealed engagement with the pressure washer outlet fitting.
