English term or phrase:vacuum service packing rings
High working pressures (above 100 bar about) make necessary to select stiffer packing rings which are not easily subject to be extruded or to be excessively packed. Pure PTFE V-rings for example can be used up to a maximum working pressure of 150 bar, while for higher pressures glass loaded PTFE V-rings have to be selected.
On vacuum service packing rings have to grant a perfect
sealing to avoid the reduction of the efficiency of various connected equipments.
