ABSTRACT:
Valve assembly for sealed reception of an elongated object, which includes a valve body defining at least one opening configured and dimensioned to permit entry of the elongated object, a valve member formed of a resilient material and defining an aperture in general alignment with the opening of the valve body, the aperture being configured and dimensioned such that insertion of the object into the aperture causes the resilient material defining the aperture to resiliently engage the outer surface of the object in a substantially fluid fight manner and a manually rotatable control mechanism associated with the valve member to selectively open and close the aperture to permit entry of the object therethrough.
