FIELD: electrical engineering.
SUBSTANCE: proposed gasket allows easy and simple assembly-disassembly of vacuum tube. Inner and outer contact surfaces of said gasket are smooth, each consisting of two cylindrical parts of different taper (31A, 31B and 32A, 32B). At least one of lateral surfaces comprises annular recess (35). Each gasket has inner and outer contact surfaces. Invention allows ruling out partial electric discharge, on the one side, between the case inner contact surface and gasket outer contact surface, and, on the other side, between vacuum tube outer surface and gasket inner surface. Inner and outer contact surfaces are cylindrical or tapered with respect to gasket axis. Each lateral surface consists of convex and concave parts. Lateral surfaces consists of two different-inclination parts. Gasket cross section features square shape.
EFFECT: easy and simple assembly-disassembly of vacuum tube.
