A world of packings, seals gaskets & lubricants

NA 731CC - Acrylic + PTFE Dispersion + Copper Corner Braided Packing

A high grade unconventional braided packing made from acrylic fibre yarns with PTFE impregnation and break-in lubricant having copper wire on outer corners in interlock braid

  • Latest development for knife gate valve industry replacing conventional packing set of acrylic fibre or PTFE braided packing with copper wire braided anti-extrusion ring at top and bottom
  • The unique structure of the packing makes it ideal in terms of heavy duty corrosion and abrasion resistance for the toughest liquid slurry and dry material handling applications
  • Copper wire on the corners eliminates distortion under maximum differential pressure while an acrylic fibre PTFE impregnated face ensures tight sealing
  • Copper, being very soft and ductile, reduces wear and tear
