ABSTRACT:
BACKGROUND OF THE INVENTION
Garden hose female fittings, when tightened onto a faucet spigot, typically do not allow the hose to rotate relative to the fitting. Therefore, if a torsional twisting force is applied to the hose, as when moving the hose from place to place, the hose will typically kink and deform. This disrupts water flow and also can damage the hose.
SUMMARY OF THE INVENTION
The female hose fitting of this invention comprises two components, namely a female hose connector and an elongated swivel nipple interfitted with the connector to allow the nipple and a hose thereon to swivel relative to the connector in response to torsional force on the hose. The nipple is retained on the connector by a pair of axially spaced, radially outwardly extending annular flanges on the nipple. An O-ring seals the space between the components.
These and other features, advantages and objects of the present invention will be further understood and appreciated by those skilled in the art by reference to the following specification, claims and appended drawings.
