Abstract
A device for reducing or eliminating the dead space in a fitting and tubing used on a disposable container by using a flexible elastic fitting that can accommodate a pinch valve or a clamp or the like closer to the flange portion of the fitting. The fitting is formed of a flange and a neck portion with a bore running through them. The neck may terminate in either a tubular section or a hose barb. The neck end section especially when in the form of a hose barb can be reinforced to provide a platform for attaching a tubing to it.
