Description 

High-transparency expandable FEP spiral coil hose designed for air and fluid transfer in chemical, pharmaceutical, and industrial applications. Excellent corrosion resistance, temperature stability, and non-stick performance.

【Full Product Description】

Overview

This transparent FEP (F46) spiral coil hose is engineered for air and fluid transfer in demanding environments where corrosion resistance, flexibility, and cleanliness are essential.
Made from 100% FEP (Fluorinated Ethylene Propylene), it offers exceptional chemical inertness, wide temperature resistance from -70°C to +200°C, and a smooth non-stick interior that ensures fast flow and easy cleaning.

The spring-like spiral structure allows the hose to extend and retract, providing excellent flexibility for dynamic operations, machinery movement, and space-limited installations.

Key Features & Advantages

1. Excellent Corrosion & Chemical Resistance

FEP is highly inert and remains stable when exposed to:

• Aqua regia

• Strong acids & alkalis

• Organic solvents

• Aggressive chemical solutions

Ideal for fluid transfer in chemical plants, laboratories, pharmaceutical equipment, and corrosion-sensitive environments.

2. Expandable Spiral Coil Design (Customizable)

Our FEP spiral coil hose can be customized according to customer requirements:
✓ Inner & outer diameter
✓ Coil pitch & stretch ratio
✓ Operating length
✓ Color (standard: transparent)

The spiral structure provides:

• Elastic expansion & contraction

• Excellent flexibility

• Easy movement and routing

• Vibration absorption

Perfect for automation, robotics, mechanical arms, and fluid supply systems.

3. High & Low Temperature Resistance (-70°C ~ +200°C)

The hose maintains excellent performance in extreme conditions:
✓ No cracking at low temperatures
✓ Stable under continuous high heat
✓ Suitable for thermal fluid transfer

4. Low Friction & Non-Stick Surface

Thanks to FEP’s ultra-low friction coefficient, the hose provides:

• Smooth internal flow

• Reduced residue buildup

• Easy flushing and cleaning

• Ideal for viscous fluids without clogging

5. High Transparency & UV Light Transmission

The clear FEP material allows:

• Real-time observation of fluid flow

• Leak detection & process monitoring

• Use in UV disinfection or UV-related applications
