Abstract
A tube coupling assembly particularly suited for ultra-high vacuum applications comprises a pair of coupling components having through passages and abutting end faces. Each end face includes an annular continuous rib or bead. A threaded coupling nut acts to drive the ribs into sealing engagement with the opposite sides of flat annular sealing washer gasket positioned between the end faces. To prevent relative rotation between the end faces and the sealing gasket, as well as to prevent torque transmission to related system components, protrusions are provided which engage the coupling components to produce a driving connection between the gasket and/or the two coupling components prior to engagement of the ribs with the gasket. Also, a resinous plastic bearing washer is used between the coupling nut and the associated coupling component to reduce torque transmission during make-up.
