This tap is used in particular at times when a tap with a long tube would be a hindrance when 

 not in use. The elbow, which is well ground on, and prevents kinking of the tubing on the tap, can 

 be turned outwards or sideways as desired and the tubing does not require to be taken off the elbow 

 after use. This operation can also be carried out with the utmost ease after removing the elbow from 

 the tap.
