Special Features  
  
  
Optimal tightness in toward meter-reading position  
  
Description  
  
As is generally known, the use of flat sealing washers of   soft  
or nonferrous metals for pressure gauges, valves and other  
fittings   is often problematic. The screwed connections have  
to be tight, and   simultaneously the parts that are to be  
connected have to be in a specific   position to each other.  
The problem is that either the pressure gauge or   valve does  
not have the desired reading or operation position, or is   not  
in the ideal position to seal effectively.  
Consequently, it becomes   necessary to unscrew and replace  
flat sealing washers by washers with   different thicknesses  
several times, until the desired sealing quality is   achieved.
