Abstract
The invention describes a leak proof shaft seal for valves and other pressurized vessels, wherein the shaft seal can deform elastically by either stretching or twisting without loosing its ability to seal all, or a portion, of said shaft from harmful fluids. Furthermore, the elastic shaft seal is immune to static pressures, since it closely surrounds a shaft and thus is protected from collapse.
