This graphite valve packing features advanced construction for superior leakage control and high integrity:

  • Strands are square plait braided to form a dense pliable packing and further enhanced with blocking agents
  • The packing’s exterior is densely coated with lubricating agents to reduce stem friction
  • A passive corrosion inhibitor is applied to prevent valve stem pitting
