A combination quick disconnect coupling and liquid cutoff valve comprises a first tubular member, and a second tubular member having a cylindrical sheath slidably disposed about and extending therefrom, sized for telescopic insertion into the first tubular member. The first and second tubular members may be coupled together and retained in that position as required. Two fluid passageways extend through the second tubular member. A third tubular member is concentrically positioned within the second tubular member and has a resilient, releasable, penetrable diaphragm at one end. A piercing pin is disposed within the movable cylindrical sheath so that when the piercing pin is exterior to the diaphragm, a first liquid passes through the connector, but when the piercing pin is inserted through the penetrable diaphragm, a second liquid passes through the connector and the flow of the first liquid is shut off.

A combination quick disconnect coupling and liquid cutoff valve comprising: a first tubular member connected to at least one length of flexible tubing and having a fluid passageway therethrough; a second tubular member connected to a plurality of lengths of flexible tubing and having a cylindrical sheath telescopically circumscribing a portion thereof and extending therefrom constructed and arranged for telescopic connection with respect to said first tubular member; said sheath being movably disposed with respect to said second tubular member; a third tubular member concentrically positioned within said second tubular member and having a penetrable resilient diaphragm member at a first end and a fluid connection to one of said lengths of said flexible tubing at a second end; and piercing pin means inwardly disposed within and attached to said movable cylindrical sheath and adapted for penetration of said penetrable diaphragm member, said piercing pin means being constructed and arranged for the passage of a first liquid therethrough when said piercing pin means is spaced from said diaphragm member and the passage of a second liquid therethrough when said piercing pin means has been inserted through said penetrable resilient diaphragm member, thereby effecting selective flow of said first or said second liquid as required.
