Chemfluor® Unpigmented PFA Fluoropolymer Smooth Inner Tube EPDM Rubber

Features and Benefits
  • Reduced extractables
    -Lower levels of extractable fluoride ions reduce silicone wafer corrosion
  • Superior chemical and heat resistance
  • Wide temperature range
  • Durable, kink resistant, with no external wire reinforcement to potentially fray
  • Easy-to-clean, non-stick smooth tube for assured sterility
  • Can be cleaned with steam, caustics, solvents or other cleaning agents
