Reinforced Graphite Packing

Inconel Reinforced Graphite Packing Set – Low Fugitive Emission, Fire Safe Certified

The Inconel Reinforced Graphite Packing Set is a high-performance sealing solution engineered for demanding industrial applications requiring low fugitive emissions, chemical resistance, and fire-safe integrity. Designed with precision and built to meet international standards, this packing set is ideal for use in gate valves, globe valves, and ball valves conforming to API 600 or API 6D specifications.

This 5-ring packing set features an inner diameter of 20 mm and an outer diameter of 33.2 mm, offering a precise fit for optimal sealing efficiency. The base material is high-purity graphite (≥99%) which provides excellent thermal stability, chemical resistance, and lubricity. It is reinforced with 20% Inconel 600/625 metal wire, enhancing mechanical strength, pressure resistance, and blowout protection under severe service conditions.

Certified under TA-Luft, ISO 15848, and API 589 (Fire Safe), this packing set delivers exceptional sealing performance even in high-risk and environmentally sensitive applications. Its design prevents stem binding caused by over-tightening of gland bolts and incorporates a buffering function that absorbs impact and vibration from stem motion—making it especially effective in pneumatic control valve assemblies.

Capable of withstanding temperatures from -200°C to +400°C in most media and up to +550°C in steam, the packing set is suitable for a wide pH range (0 to 14) and pressures up to 25 MPa. It also supports shaft speeds of up to 2 m/s, making it versatile across a wide array of process conditions.
