The Expanded Graphite Valve Packing Plant produces high-performance valve stem packing engineered for demanding industrial applications. Made from expanded graphite, carbon fiber, and Inconel wire, this packing ensures exceptional durability and reliability. Designed for valve stems ranging from 4 mm to 18 mm, it can withstand pressures up to 300 bar and meets PN300 standards. Its advanced composition and design make it ideal for high-temperature environments, delivering superior sealing performance and long-lasting operation in critical conditions. https://www.magpievalves.com/graphite-packing.html
Our Fugitive Emission Control Gasket Plant specializes in manufacturing high-performance gaskets designed to meet strict environmental standards. Combining metal strips with non-metallic fillers, these gaskets ensure reliable sealing while minimizing emissions. Engineered to comply with ISO 15848 standards, they guarantee a maximum leakage rate of just 50 ppmv. Capable of withstanding pressures up to 50 MPa, these gaskets are ideal for demanding high-pressure applications. Their exceptional sealing performance makes them the perfect choice for industries seeking durable and environmentally responsible solutions. https://www.magpievalves.com/graphite-gasket.html
The Custom Metal Jacketed Gasket Plant specializes in manufacturing premium gaskets for critical sealing applications in valves and heat exchangers. Constructed from durable materials such as SUS 304, SUS 316, aluminum, or carbon steel, these gaskets withstand high pressures of up to 25 MPa. With flexible graphite or PTFE fillers, they deliver exceptional sealing performance, making them suitable for a wide range of industrial environments. The plant provides fully customizable solutions tailored to specific customer requirements, ensuring reliable, long-lasting performance in even the most demanding applications. https://www.magpievalves.com/graphite-gasket.html
Graphite sheets and yarns are versatile materials prized for their durability and flexibility. Available in various forms—including reinforced composite sheets, rolls, and tapes—they are extensively used to manufacture gaskets and sealing components across industries such as petrochemical and steel. With their high carbon content and strong tensile strength, these graphite products are well-suited for demanding applications requiring reliable performance.
Additionally, specialized graphite yarns are produced for weaving into packing materials, while graphite fabrics serve as raw material for cutting precise gasket shapes used in pipeline sealing and other critical sealing applications.

PTFE packing, made from polytetrafluoroethylene, is widely recognized for its outstanding chemical resistance and low friction properties. These gland packings are manufactured using carefully selected PTFE filaments or exfoliated graphite acrylic fibers, braided to form a strong yet flexible structure with consistent quality. This construction makes them ideal for continuous operation across a broad temperature range.
Our PTFE packing range includes valve stem packings and chemically resistant packings designed for pumps and rotary equipment. They can withstand exposure to nearly all known chemical substances and offer excellent temperature resistance up to +260°C. The PTFE dispersion finish ensures a smooth, low-friction surface that prevents leakage through the braid, delivering reliable sealing performance and extended service life.
