• Temperature Tolerance: Capable of withstanding extreme temperatures from -100°F to 450°F.

Pharmaceutical Applications

In the pharmaceutical sector, cleanliness and non-contamination are paramount. PTFE lined metal hoses serve this purpose effectively.

• FDA Compliance: Many PTFE products meet FDA standards making them suitable for biopharmaceutical applications.
• Easy Cleanability: The smooth surface of PTFE prevents any buildup of residues.

Food and Beverage Industry

PTFE lined metal hoses are increasingly used in the food and beverage industry due to their hygienic properties.

• Non-stick Surface: Reduces the chance of food contamination.
• Temperature Extremes: Capable of handling both hot and cold applications.

Advantages of PTFE Lined Metal Hoses

Utilizing PTFE lined metal hoses can yield numerous advantages, making them a preferred choice in many industries.

Durability

• Robust Construction: The metal outer layer provides strength, while the PTFE lining enhances chemical resistance.
• Wear Resistance: Can withstand vibration, movement, and pressure fluctuations.

Flexibility

• Bend Radius: Offers greater flexibility than traditional metal hoses.
• Installation Ease: The lightweight nature makes for easier installation in confined spaces.

Leak Prevention

• Seamless Design: Reduced risk of leaks compared to non-lined alternatives.
• High Integrity: The PTFE lining minimizes the chance of failure under pressure.
