See lessWhat is an acceptable leak rates for o-rings?
An o-ring should not leak when tested with a helium mass spectrometer in the range of 10-6 or 10-7 Torr. Acceptable leak rates would be subjective and relate to the materials being processed in the furnace and the hot zone deterioration that can be tolerated with a leaking o-ring or system.

Typically if maintained well the life expectancy of a vacuum furnace should be 30 years or more. The critical component is the vessel. It is like the foundation of a house, and if maintained it will last a long time. Cooling water quality is critical to vessel life and longevity. All other components can be repaired or replaces, but when the vessel deteriorates furnace life begins its demise.
