Chemfluor® PTFE Fluoropolymer Helically Convoluted Inner Tube
Platinum-Cured Silicone Cover
Stainless Steel Braid, Low Profile

Features & Benefits

See Chemfluor® fluoropolymer inner tubes (WCS/BCS)
Silicone Cover
  • Durable, extremely flexible, ultra pure platinum-cured silicone
  • Extruded directly over WCS Series hose
  • Extremely smooth for easy cleaning and assured sterility
  • No place for bacteria to accumulate
  • Hose assemblies may be autoclaved or SIP cleaned
  • Cover is locked to stainless steel braid reinforcement so that hose and cover flex as one unit, with no bulges or creases; tear resistance also improved due to right fit
  • Braid fraying minimized, reducing risk of hand injuries from wire braid punctures
  • Enhanced thermal insulating properties
  • Burn potential from accidental contact greatly reduced

Details

N/A Construction:

  • Inner Tube:
    -Chemfluro® PTFE fluoropolymer inner tube
  • Cover: Platinum-cured silicone
  • Reinforcement:
    -304 stainless steel braid
    -High tensile strength
Fittings
  • PermaSeal® crimp-style
    -Over 40 styles in a wide range of materials
    -Standard: 316L stainless steel
    -Single stainless steel crimp collar design locks in hose fitting and seals off silicone cover, which prevents cleaning media from seeping under cover
    -This design eliminates the need for a secondary crimp collar or plastic heat shrink tubing
    -Also assures hose pressure rating to rated operating pressure
