Graphite Rings

---

Characteristics

• Excellent thermal stability: Resistant to low and high temperatures (-200 to 650 °C) in oxidation environments and 3000°C in inert or reducing environments.
• Chemically inert: Resistant to fluids with a pH range of 0-14 (except strong oxidizers such as nitric or sulphuric acid).
• Low coefficient of friction.
• Ease of installation.

Applications

• High temperature, high pressure steam.
• Hot water, oil, heat exchange fluids.
• Low-temperature liquids.
• Organic and inorganic fluids except for strong oxidizers such as nitric or sulphuric acid.
• High temperature and pressure liquid valves.
• High temperature and pressure gas valves.
• High temperature joints.
• Packing rings, turbine rings, and piston rings.
• Special vacuum furnace applications.
