Graphite Packing
Graphite packing is precision-braided from high-quality graphite yarn, often reinforced with fibers or metal wires (stainless steel, copper, nickel, carbon fiber, pre-oxidized fiber, or glass yarn) to enhance strength and durability. Except for a few strong oxidizers, it is suitable for sealing hot water, superheated steam, heat transfer fluids, ammonia solutions, hydrocarbons, and cryogenic liquids. It is widely used for valves, pumps, and reactors in demanding high-temperature, high-pressure, and corrosive applications, making it a truly versatile sealing solution.
Key Features
Superior High-Temperature Resistance
Continuous operation: 450–650°C ;Short-term peaks: up to 800°C ;Slightly lower limits in strongly oxidizing atmospheres
Excellent Chemical Stability
Inert to most chemical media ;Resistant to acids, alkalis, steam, and solvents ;Only a few strong oxidizers are not compatible
Self-Lubricating Performance
Layered graphite structure reduces friction ;Minimizes wear on shafts and valve stems ;Extends equipment service life
High Strength & Compressibility
Flexible and resilient ;Maintains reliable sealing even under high pressure
Thermal & Electrical Conductivity

Product Handling & Storage Guidelines
Never use the product at its maximum rated temperature and pressure. Consult the manufacturer for further information.
The peak temperature can be sustained only for short exposure periods.
With weakly oxidizing agents and hot air, the temperature must be limited to 450 °C.
With steam and non-oxidizing fluids, the temperature must be limited to 650 °C.
Flexible graphite and carbon yarns shall not be used with oxidizing fluids.
