  • BIGPIECE

    Vacuum line has four ports, made up of two valves each - one extending from the inert line and the other from the vacuum line, both are bent to a 90° angle. Spacing between ports is 170 mm. The inert gas line has a 18/9 ball joint connection for use with a bubbler or inert gas source. Both of the ends of the manifold have a #9 o-ring joint and are supplied complete with a cap style stopper.

    The manifold connects to our dual-trap assembly with a shut-off valve. The dual-trap is approx. 55 mm OD X 200 mm in length and has two 35/20 socket joints to connect it to the manifold and main trap. Main trap assembly has two high-vacuum valves. O-rings used: Sizes-112, -217, -226

    The inert line is approximately 45" wide X 23" height.
