CA 2081925

A valve insert (40) is adapted to be removably mounted as a unit on a cylinder valve (41) to selectively enable a flow of fluid therethrough when a male cou- pling section (52) is inserted into the outlet of the cylinder valve. The improved insert includes a tubular body (55), a valve member (58) mounted for sealed sliding movement relative to the body, biasing means (97) and a docking member (59) mounted on the valve element and adapted to engage the nose of the male section. When the malesection engages the insert and displaces a sealing cushion (80) off its seat (72), the pressure of fluid will urge the valve element (58) into tighter sealed engagement with the male section.
