ABSTRACT:
The invention is an improved hydraulic coupling wherein the male and female fittings include complementary tapered surfaces and the male fitting is axially urged into engagement with the female fitting by means of a threaded nut. The male fitting is provided with a shoulder behind its tapered surface and abuts a surface on the female member to thereby limit the axial movement of the male member and prevent nose collapse.
