Overview
Ultra-Flexible Convoluted PTFE Hose for Heavy Duty Applications
- Corrosion Resistant
- Cleanable
- Flexible
UltraFlex™ heavy duty hose is made with the thickest seamless PTFE liner in the industry and offers the largest size range (1/2" - 6") which makes it ideal for nearly all demanding high purity and chemical applications. The open pitch spiral convolutions facilitate cleaning because they're self-draining, and the tight bend radius of UltraFlex hose is perfect for space-constrained locations. To ensure continuous fluid contact with PTFE throughout the hose assembly, the PTFE liner can be cuffed and flared through for a continuous fluid conduit.
UltraFlex™ 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 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 ernbrittlement like rubber, even with extreme thermal cycling.
Flared-Thru Fittings
UltraFlex™ thick PTFE liner can be passed through the end fitting and flared radially outward against the sealing face to provide a continuous PTFE fluid conduit.
