ABSTRACT:
A tap comprising a tubular body open at one end and closed at the other end by a flexible resilient diaphragm. The diaphragm is connected to a valve element arranged to close a valve seat at said one end of the body. The body of the tap is made of a material of lower permeability than that of the diaphragm, and the diaphragm is closed to the atmosphere by a cap or a coating. The edge of the valve element is flush with said one end of the body.
