Convoluted Hose, PTFE, High Pressure Rating, Excellent Flexibility
The MultiFlex™ Convoluted Hose, PTFE Hose 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".
Product Features & Benefits
- 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.
Braid Options Available

Hose Options
Electrically Heated Option
Electrically heated options may be applied to many of the hose assemblies available from PureFlex®. Our superior insulations and precisely applied heating elements provide the most temperature-stable heated hoses on the market. PureFlex heated hoses are excellent for maintaining viscosity control, freeze protection, and dispensing temperature-sensitive media. Temperature options available from ambient to 450°F (hose selection dependent).
