Abstract
A main body housing includes a main body port. An O-ring sleeve is contained in the housing. The O-ring sleeve includes an O-ring sleeve port and O-rings mounted on either side of the O-ring sleeve port. The O-ring sleeve is not rotatable with respect to the main body housing and is translatable with respect to the main body housing between an open O-ring sleeve position and a closed O-ring sleeve position. The O-ring sleeve port aligns with the main body port when the O-ring sleeve is in the open O-ring sleeve position and the O-ring sleeve port is sealed from the main body port by the O-rings when the O-ring sleeve is in the closed O-ring sleeve position.
