This disclosure relates generally to hose couplings useful for mining applications, more particularly to a fluid coupling capable of generally fully tightened by hand, including a visual lock for visual indication and safety when in a hand-tightened position. The coupling generally includes a male portion, a female portion, a retaining member and a locking member. The male portion passes through the retaining member, and the retaining member threadingly engages the female member. The locking member prevents unthreading of the retaining member from the female member.

Hand tightened hydraulic fitting

An improved quick connect hose coupling for connecting a hose to a fixture has a hose stem portion including a hose insert portion, a fixture portion including a fixture connection portion, and a joinder portion. The joinder portion includes a male connection portion and a female connection portion. Each of the male connection portion and the female connection portion are adapted to join in a sealing and locking manner upon being pushed together. The coupling further includes threads and wrench mating flats adapted to disconnect the hose from the fixture. It is improved by the male connection portion being a unitary structure having a leading support cylindrical surface, a following support cylindrical surface, and a transition, surface intermediate therein between. The leading support cylindrical surface has a leading radius. The following support cylindrical surface has a following radius. The following radius is larger than the leading radius.

Quick connect coupling

A quick connect coupling having a clip, a port having an interior annular groove adapted to support the clip, a forward cylinder, a rear cylinder, and a first transition ramp, and defines a port peak distance. The coupling also has a sealing element. Additionally, the coupling also has a stem having a male connection portion including a forward annular seal groove adapted to receive the sealing element, an annular lead-in surface, a leading support cylindrical surface, a following support cylindrical surface, a camming ramp, and defines a stem peak distance. The port has an intermediate cylinder between the forward cylinder and the rear cylinder and has a second transition ramp between the forward cylinder and the intermediate cylinder and the male connection portion has a centering ramp and an intermediate support cylindrical surface between the leading support cylindrical surface and the following support cylindrical surface.
