Graphite self sealing ring consists of low sulfur expandable graphite by moulding, precise size, density can be determined, and without any additional filler or adhesive. Graphite purity greater than 98%, do not need to carry out anti-corrosion treatment. Generally, the cross section of the packing ring is square, and it can also be wedge shaped or V shaped, and the two parts can be used for high pressure.

Enhanced graphite self sealing ring
Molded from pure flexible graphite, lined with metal, stainless steel foil, mesh, or other materials.
Application
With the characteristics of expanded graphite, can withstand severe alternating temperature and pressure, is the valve and all kinds of static sealing ideal filler. In addition to the stems are severely damaged avoid use. It can used alone, but also with JJ-771 high carbon fiber packing end ring used in combination, can prevent filler extruding.
