  • Swiveling hose coupling
    Patent number: 6508492
    Abstract: A swiveling hose coupling comprising first and second nipples and a cylindrical shell. The cylindrical shell includes a swivel shell, and first and second retaining rings. The swivel shell is set between the first and second retaining rings. The first and second nipples are in proximity with one another within the cylindrical shell, but are separated by antifriction bearings. The first and second nipple rotate independent of one another to prevent inhibition of liquid flow in a hose coupled to the swiveling hose coupling. The first and second nipples are set in the cylindrical shell, using journal bearing grooves on the first and second nipple, in which the journal bearing grooves abut the first and second retaining rings. Reference points for the application of a hose coupling clamp are provided by an indexing ring on each of the nipples.
