A hose swivel connection apparatus for connecting a pair of hose sections, the swivel member having male and female swivel members with underlap and overlap portions, respectively, forming radially-facing annular ball grooves between which bearing balls are captured to provide swiveling and to hold the swivel device together, and a seal between the swivel members, preferably a ring seal positioned between a pair of axially-facing opposed seal-abutment surfaces. The invention also involves hose-end couplings on swivel members of a swivel device, the couplings each having a sleeve member over and permanently secured to a hose section and being adapted for snap-engagement with one of the swivel members. |
