e6.3.Graphite Ring

CONSTRUCTION:
TRG 241 Die formed Graphite Ring
  TRG die formed ring are made of low-sulphur expanded graphite  without any fillers or binders. They are compressed in precise 
moulding tools to the required density. Due to the high purity of the
  material (>98%), no special corrosion protection is required. In general, it has square section and also has V-shaped and 
  wedge-shaped section, the rear two kinds style are suitable for high  pressure sealing. 

TRG 241E-Reinforced Die formed Graphite Ring
  Moulded from pure flexible graphite with reinforcement, the insert  materials stainless steel foil or mesh etc. are available on request. To  protect against oxidation, the stainless steel cap is necessary. 

   241K-Die formed Graphite Ring with Corrosion Inhibitor  Corrosion inhibitor acts as a sacrificial anode to protect the valve stem 
and the stuffing box.
    241EK is reinforced graphite ring with corrosion inhibitor. 

APPLICATION:
It has all properties of expanded graphite, can bear violent alteration of temperature and  pressure. It is ideal packing for valves and static seal in almost all applications. Can be used  as stand-alone packing or in combination 244 high carbon fiber anti-extrusion packing rings,  except when stems are severely damaged.  TRG have cooperation with more famous Valve manufacturer in the world.
