NA 718

Expanded pure graphite braided packing with a reinforcement of high grade structural carbon yarns in interlock braid

  • A true multipurpose packing for a wide range of applications
  • High grade carbon yarns criss-cross the packing to emerge at the corners, providing mechanical strength and extrusion resistance to the packing
  • Excellent dry running capabilities reduce plant wide flush water use
  • A corrosion inhibitor prevents stem pitting
  • The packing fills into worn out surfaces and pittings, thus cutting out leak paths.
  • Dissipates heat without chemical hardening, resistant to chemicals

Available in rope and ring forms
