Chemfluor® PTFE Fluoropolymer Helically Convoluted Inner Tube
Polypropylene Braid
Open Pitch

Features and Benefits

Chemfluor® PTFE inner tube
Polypropylene braid
  • Ultraviolet stabilized
  • Offers good chemical resistance against many types of acids
  • Resists abrasion better than stainless steel reinforcements
  • Lightweight, with minimum force to bend
    -Easy to transport, connect and disconnect
    -Less strain on adjoining equipment/scales
  • Braid fraying minimized, reducing risk of hand injuries from wire braid punctures
  • Does not conduct internal heat as readily as stainless steel braided hoses
  • Burn potential from incidental contact greatly reduced
