BOLT TORQUE

Bolt tightening torques and patterns are necessary to assure a leak tight vacuum seal on Conflat (CF) flanges. All fasteners and threads will be precision cleaned. This requires that lubrication is added to the threads to prevent galling. The following lubricants may be used on fasteners for MPEX Device CF flanges.
