Graphite packing is a highly efficient sealing material valued for its self-lubricating properties, dimensional stability, and exceptional resistance to gases, fluids, and corrosion. Designed to perform under the most demanding conditions, it delivers superior sealing performance, extends equipment life, and minimizes maintenance requirements.

This packing is especially suitable for dynamic sealing applications, such as centrifugal pumps, valves, and other rotating or reciprocating equipment handling water, petroleum derivatives, steam, and various chemicals. It performs reliably in high-speed and high-pressure environments, operating effectively at temperatures up to 450°C, with a wide pH tolerance from 0 to 14, and linear velocities reaching 40 m/s.

Made from high-quality graphite, the material offers a low coefficient of friction, high thermal conductivity, and outstanding chemical resistance. It remains soft, pliable, and resilient even under extreme temperature and pressure, ensuring consistent sealing integrity and long-term performance in critical industrial applications. https://www.magpievalves.com/graphite-packing.html

Graphite Packing Manufacturer from China | Magpie

China Graphite Packing Manufacturer Provides Low-E Flexible Graphite Packings, Reinforced with Fibers or Steels, for Valves & Pumps in Harsh Conditions.

PTFE gaskets, made from a synthetic fluoropolymer of tetrafluoroethylene, are highly regarded for their exceptional versatility and performance. Known for being hydrophobic and having an extremely low coefficient of friction, they provide reliable sealing in environments where chemical resistance and purity are essential. PTFE gaskets exhibit outstanding resistance to almost all chemicals, making them ideal for a wide range of industrial and process applications.

To improve mechanical strength and minimize creep under high pressure and temperature, PTFE can be reinforced with fillers such as carbon or graphite. These gaskets are available in several variants—including virgin PTFE, glass-filled, carbon-filled, etched, and expanded PTFE—each designed to meet specific sealing and operational requirements.

Key advantages of PTFE gaskets include exceptional chemical inertness, high dielectric strength, broad temperature tolerance (from -200°C to +260°C), and excellent resistance to moisture and aging. Because of these properties, PTFE gaskets are widely used in piping systems, flange connections, and industries such as food processing, water treatment, chemical manufacturing, and pharmaceuticals, where cleanliness, durability, and reliability are critical.

PTFE / EPTFE Gasket Manufacturer from China | Magpie

PTFE Gasket Manufacturer from China: Low Emission Gaskets, Typically Spiral Wound Gaskets, PTFE/EPTFE Fillers, Metal Inner or Outer Rings, Low Friction.

Graphite gaskets are extensively utilized across industrial sectors for their outstanding performance and reliability. Renowned for their excellent resistance to corrosion, high pressure, and extreme temperatures, these gaskets are engineered to perform under the most demanding conditions. Made from soft yet exceptionally strong graphite materials, they provide superior sealing efficiency with low friction, minimizing energy loss and heat generation during operation.

To enhance mechanical stability and resilience, filler or reinforcement materials are often incorporated. Graphite gaskets are available in various types—such as reinforced, tanged, foil, pure, unimetal, unigraph, and eyelet versions—each tailored to meet specific application needs. Their construction may include pure graphite or graphite composites combined with metal cores to ensure optimal performance in harsh environments.

With their broad temperature tolerance, flexibility, durability, and impermeability to gases and liquids, graphite gaskets are widely used in high-pressure and high-temperature systems. They are particularly well-suited for applications involving steam, aggressive chemicals, and other challenging media where long-term sealing stability and reliability are essential.
