Product Features

 

Superior chemical resistance

The FEP lining can withstand strong acids (such as sulfuric acid and hydrochloric acid), strong alkalis, organic solvents (such as acetone and ethanol), and oxidizing agents, with minimal reaction.

01

High cleanliness and low adsorption

The inner wall is smooth and pore-free, preventing microbial growth or medium residue, and meets GMP/FDA standards for the pharmaceutical and food industries.

02

High-Temperature and High-Pressure Resistance

The operating temperature range is typically -40°C to 240°C, with some models capable of withstanding short-term temperatures up to 232°C (e.g., steam sterilization). The stainless steel wire reinforcement layer significantly enhances pressure resistance.

03

Flexible and Kink-Resistant

The steel wire reinforced structure provides support, ensuring the inner wall remains smooth without wrinkles when bent, making it suitable for complex piping layouts.

04

Safety and compliance

Adhesive-free design eliminates contamination risks, certified to USP Class VI and other standards.

05

 

Applications
 

Pharmaceutical/biotechnology

Used for sterile fluid transfer, bioreactor connections, and CIP/SIP (clean-in-place/sterilize-in-place) systems.

Chemical/semiconductor

Conveys corrosive chemicals, high-purity solvents, or ultra-pure water.

Food and Beverage

Hygienic fluid transfer for dairy products, juices, etc., preventing flavor adsorption.

Laboratory and Industrial

High-temperature steam, hot oil, or gas transfer, replacing traditional silicone tubing to extend service life.

 

Selection Tips

 

 

1

Liner Material: Prefer FEP (no PTFE) for its greater flexibility and high transparency, facilitating fluid condition observation.

2

Reinforcement Layer Design: 316L stainless steel wire, suitable for high-pressure or vacuum environments (e.g., pharmaceutical filling lines).

3

Certification Requirements: Confirm certifications such as FDA, USP Class VI, or ISO 8031, especially for medical/food industries.

4

Dimensions and Bending Radius: Select inner diameter based on flow rate and ensure the minimum bending radius fits the installation space.

FAQ

 

 

Q: How to choose between FEP and PTFE-lined Silicone hose?

A: FEP: High transparency, more flexible, suitable for clean applications at temperatures ≤177°C (e.g., pharmaceuticals, food).
PTFE: Higher temperature resistance (260°C), suitable for high-temperature, highly corrosive environments.

Q: Can it withstand steam sterilization?

A: It can withstand 30 minutes of steam cleaning at 130°C, but prolonged exposure to high temperatures (>177°C) may shorten its lifespan.

Q: How can corrosion of the steel wire layer be prevented?

A: Select the 316L stainless steel wire reinforced model and regularly inspect the integrity of the outer coating in acidic environments.

Q: How is the bending radius determined?

A: The minimum bending radius is generally 2–3 times the tube diameter; excessive bending may damage the steel wire layer.

Q: Can it be used for negative pressure suction?

A: The steel wire-reinforced type can withstand certain negative pressure, but must avoid exceeding the vacuum limit (e.g., -0.95 bar).

Q: How do you determine when the silicone hose needs to be replaced?

A: Cracks or hardening of the outer silicone layer, or fogging or leakage of the inner lining layer.
