W201 Flexible Graphite Ring
W201D 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 moulding 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.
