Angle Valves, Up to Air Valve, and Pressure Gauge Attached to RbQ Vacuum Chamber

[Jeff, Daniel]

We attached the 2.75" CF Angle Valve, the 2.75" All Metal Angle Valve (angled so that the Residual Gas Analyzer fits), the up-to-air valve, and the Agilent FRG702 pressure gauge to the RbQ Vacuum Chamber. None of the bolts are tightened. So that the magnet doesn't move, we used 1.25" long 1/4-28 bolts to attach the pressure gauge. Hopefully this works well.

I tightened all the bolts until there was flange to flange contact around the whole connection. The 1.25" long bolts did fine, but I still think longer bolts are generally advisable to avoid stripping a thread.
