Product Description
Our China Graphite Yarn Braided Packing is engineered for exceptional sealing performance in demanding industrial environments. Manufactured from 100% pure graphite continuous yarns, this packing delivers outstanding durability, thermal stability, and chemical resistance. The high-purity graphite structure provides excellent conformity to shaft and stem surfaces, ensuring a tight seal even under fluctuating operating conditions. With an available size range of 6 to 22 mm and a pressure rating up to 300 bar, this packing is particularly well-suited for feed pumps, high-pressure rotary equipment, and other critical systems. Its naturally low friction coefficient significantly reduces heat generation, wear, and energy consumption, extending equipment service life and minimizing maintenance requirements. Designed to perform reliably in high-temperature and high-pressure service, this graphite yarn braided packing offers: Superior thermal conductivity, allowing efficient heat dissipation Excellent chemical compatibility, suitable for a wide variety of media Minimal shaft/stem wear, thanks to its smooth, lubricated graphite fibers Reliable sealing performance, even under dynamic conditions This makes it an ideal choice for industries such as power generation, petrochemical, oil & gas, and general industrial applications where high reliability, low leakage, and long service life are essential.

As a leading manufacturer of industrial valves, packing, gaskets, and seal kits, Magpie Valve is a research-driven enterprise committed to advancing valve technology through material science, precision engineering, and third-party-verified performance. Our mission is to redefine the role of valves in industrial systems by focusing on the core factors that determine long-term reliability—especially sealing performance. In today’s valve industry, large-scale machining is no longer the primary challenge in China. Instead, the true obstacles lie in the mechanical behavior of non-metallic materials, advanced surface-coating processes, and the study of friction and wear mechanisms. These critical yet often overlooked areas represent the real bottlenecks to achieving high-performance, low-emission valves.
Our multidisciplinary team includes nuclear-grade sealing engineers, valve experts, materials scientists, and electromechanical specialists. By uniting academic research with practical engineering experience, we deliver high-integrity valve solutions built on scientific understanding. Magpie Valve has conducted extensive research in partnership with renowned institutions such as the National Key Laboratory of Friction at Lanzhou University of Technology, the Ningbo Institute of Materials, East China University of Science and Technology, and the Shanghai Institute of Ceramics. These collaborations have enabled systematic studies of low-leakage graphite sealing technology and provided clear resolutions to the root causes of sealing failure.
Supported by rigorous testing and authoritative third-party certification, Magpie Valve has earned numerous internationally recognized credentials, including API 622, API 624, API 641, ISO 15848-1, TA-LUFT, and ISO 15848-1 CC3. To date, we have tested nearly 500 valve products, including gate, globe, and ball valves, under extreme operating conditions—from 400°C to -196°C and pressures up to Class 2500 LB. These efforts not only ensure compliance with international standards but also set new benchmarks for reliability, safety, and innovation across the global valve manufacturing industry.China manufacturer offers high-quality industrial products with competitive pricing and advanced production capabilities.
