Aramid Fiber PTFE Packing: The Industrial Sealing Revolution

Extreme Condition Performance

When refinery valves operate at 280°C and 150 bar, conventional packing fails. Hongwo’s aramid fiber PTFE packing delivers unmatched performance through:

45° fiber braiding (vs standard 90°)
Pre-compressed PTFE matrix
Vibration-optimized fiber density
