Main Products:
Die Formed Graphite Rings
Die-formed graphite ring is made of low-sulphur expanded graphite without any fillers or binders.They are compressed in precise tools to the required density.Due to the high purity of the material(>99%),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.
R Reinforced Graphite Rings
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.
