Abstract
The present invention is a hydraulic coupling with an O-ring seal and a stop wall. The O-ring sealing works conventionally to provide a hydraulic seal, while the stop wall limits the range of adjustment for the male fitting. The male fitting is prevented from further inward axial movement because of the abutment of the stop wall with the annular edge of the fitting.
