Introduction to Graphite Sealing Rings

Graphite sealing rings feature precise dimensions and controllable density, and contain absolutely no added fillers or binders. With a graphite purity exceeding 98%, they require no further anti-corrosion treatment. Typically, the cross-section of these packing rings features a 45-degree or 30-degree bevel, making them suitable for high-pressure applications. Characterized by excellent self-lubricity, high resilience, and corrosion resistance, this product is ideal for both dynamic and static sealing applications in equipment such as valves and pumps.

Reinforced graphite self-sealing rings are manufactured by molding pure flexible graphite around a metal liner; the reinforcing material consists of stainless steel foil, mesh, or other suitable materials. This reinforcement enhances pressure resistance, making the product suitable for operating conditions involving both high pressure and high temperature.
