MultiFlex™PTFE Hose for Higher
Pressure Applications




Combines Excellent Flexibility with a High Pressure Rating

MultiFlex combines excellent flexibility with a high pressure rating. The seamless open pitch spiral PTFE convolutions facilitate cleaning because they're self-draining. MultiFlex is perfect for demanding high purity and chemical applications. Available in sizes 1/2" to 3".

UltraFlex Braids

MultiFlex Advantages

  • Corrosion Resistant - PTFE is fully resistant to the broadest range of industrial chemicals and has a zero corrosion rate with lower life cycle costs.
  • Cleanable - Non-Stick, low porosity tube is self cleaning and does not trap bacteria and can be cleaned with steam, detergents, caustics or solvents.
  • Sanitary – FDA- approved materials meet or exceed Pharmacopoeia class VI and 3A standards.
  • Compatible - Will not contaminate or impart a taste, color or odor to any media.
  • Flexible - Ultra flexible engineered design that resists cracking and stress corroding.
  • Durable - Engineered for extended use in hostile environments involving severe chemical, thermal, and mechanical stresses. Does not suffer from aging or embrittlement like rubber even with extreme thermal cycling.
