ABSTRACT:
A coupling mechanism for removably connecting a fluid line to an apparatus such as a mass flow controller and includes a flange member for connection to the apparatus so that it is cantilevered from the apparatus and provides a fluid connection with a bore opening that is vertically aligned. A yoke member is dimensioned to extend over the flange member and have a corresponding fluid conduit and bore that can be aligned vertically with the bore opening on the flange member. A seal member can be positioned between the yoke member and the flange member. A spacer member is mounted in the yoke member and a fastener member can be aligned vertically to exert a force on the flange member to apply a sealing pressure to the seal member while locking the yoke member to the flange member.
