PTFE Braided Hose is a high-performance hose constructed with a PTFE inner tube as its base, reinforced with an outer layer of stainless steel wire or other high-strength fiber braided layers. This type of hose is widely used in fluid conveyance systems requiring high temperatures, high pressures, strong corrosion resistance or high purity.

Braided PTFE hose Advantages and Features

High-temperature resistance

Can withstand operating temperatures of up to 260°C or higher.

Strong Corrosion Resistance

Resistant to almost all industrial chemicals, including strong acids and alkalis.

High-Pressure Resistance

The outer stainless steel wire braid provides excellent pressure-bearing capacity.

Non-Stick Property

The PTFE inner wall does not easily adhere to substances, is easy to clean, and is suitable for high-purity applications.

Low Friction Coefficient

The smooth inner wall reduces fluid flow resistance.

Aging and UV Resistance

Suitable for indoor and outdoor environments.

Customer Application Cases for PTFE lined braided hose

Case 1: Pharmaceutical Company CIP System

A European GMP-certified pharmaceutical factory selected our anti-static PTFE braided tubing for its CIP/SIP system. After two years of use under high-temperature sterilization (121°C) and strong alkaline liquid rinsing conditions, the tubing maintained stable performance. The customer reported a 30% improvement in cleaning efficiency and a significant reduction in product contamination risks.

Case 2: Racing Brake System

An international racing team used our PTFE stainless steel braided brake fluid tubing in their high-performance race cars to replace traditional rubber tubing, significantly improving brake response speed and burst resistance, ensuring safety and precise control during races.

Case 3: Chemical Conveyance in Semiconductor Factories

A large Asian wafer fab selected our ultra-clean PTFE braided tubing for conveying high-purity ammonia water and hydrofluoric acid. Through customized outer sleeves and explosion-proof protective layers, the tubing maintains high chemical stability while meeting Class 100 cleanroom standards.

FAQ

Q: 1. What is a PTFE braided hose used for?

A: PTFE braided hoses are widely used for transferring aggressive chemicals, high-purity fluids, steam, gases, and high-temperature media. Common applications include pharmaceutical processing, chemical transfer, automotive brake lines, food-grade fluid handling, and semiconductor manufacturing.

Q: 2. Is PTFE braided hose compatible with all chemicals?

A: PTFE is chemically inert and offers excellent compatibility with nearly all industrial chemicals, including strong acids, alkalis, and solvents. However, compatibility should still be confirmed for specific fluids like molten alkali metals or highly reactive fluorinating agents.

Q: 3. Can PTFE braided hose be used for food and beverage applications?

A: Yes. PTFE braided hoses are available in food-grade versions that comply with FDA, 3-A, and USP Class VI standards. They are ideal for transferring milk, juice, wine, syrups, and cleaning agents in hygienic environments.

Q: 4. What temperature range can PTFE braided hose withstand?

A: Standard PTFE braided hoses can operate continuously from -70°C to +260°C (-94°F to +500°F). Some high-performance versions may support even higher peaks depending on construction and reinforcement layers.

Q: 5. Does PTFE braided hose prevent leakage and permeation?

A: Yes. The PTFE inner core offers low permeability, and the stainless steel or fiber braided outer layer provides mechanical strength, minimizing leakage and diffusion. For critical applications, multi-layer and anti-static designs are also available.

Q: 6. How long do PTFE braided hoses typically last?

A: Service life depends on the working environment, pressure cycles, temperature exposure, and chemical media. Under optimal conditions, PTFE braided hoses can last 5–10 years or more. Regular inspection and preventive maintenance are recommended.
