The China M600S Graphite Packing Manufacturer specializes in producing high-quality die-formed graphite rings engineered specifically for cryogenic valve applications. Manufactured from premium expanded graphite, these packing rings are designed to meet the rigorous performance requirements of ISO 15848-1 and API 622, ensuring industry-leading emission control, durability, and sealing reliability.
With a pressure resistance of up to 310 bar (4500 PSI), the M600S graphite packing delivers stable and secure sealing performance even in ultra-low-temperature environments where conventional sealing materials fail. The die-formed structure provides excellent resilience, dimensional stability, and conformity to valve stems and stuffing boxes, ensuring consistent sealing during thermal cycling.
Ideal for LNG systems, cryogenic storage, air separation units, and other applications where extreme cold conditions demand maximum safety and leakage control, these graphite packing rings offer a trusted solution for operators seeking long-term reliability and compliance with global low-emission standards.
