PTFE Corrugated Tube for Base Station Liquid Cooling

Unmatched Temperature Range: -196°C to +700°C

Most base station liquid cooling hoses on the market are rated for -40°C to +150°C — barely meeting the outdoor demands of 5G AAU installations. SUKO’s PTFE corrugated tube operates from -196°C to +700°C. That’s a 500°C+ safety margin at the high end and a 150°C+ margin at the low end.

PTFE Corrugated Tube for Base Station Liquid Cooling

Why this matters for 5G base stations:

Product Overview

PTFE corrugated tube is a flexible pipeline component manufactured from polytetrafluoroethylene through continuous extrusion on specialized corrugating machines. Its corrugated wall structure provides excellent bending performance and fatigue resistance, while retaining PTFE’s inherent chemical inertness and ultra-wide temperature stability.

Key Features:

Core Advantages:

• Effectively absorbs vibration, noise, and thermal expansion from pipeline systems

• Compensates for minor deviations in pipe connections and eliminates residual stress

• Suitable for repeated motion in high-temperature areas with excellent anti-fatigue performance

• Good flexibility, high-temperature resistance, and corrosion resistance

• Outstanding coefficient of friction — among the lowest known

• Excellent acid and chemical resistance

• Water repellent and electrically resistant

Why Base Station Liquid Cooling Needs PTFE Corrugated Tube

5G base station liquid cooling systems have four critical requirements that make PTFE corrugated tube the superior choice:

1. Extreme Outdoor Temperature Variations

AAU (Active Antenna Unit) is installed on outdoor towers, exposed to severe temperature swings from -40°C to +85°C. PTFE corrugated tube operates from -196°C to +700°C — far exceeding real-world requirements with a massive safety margin. Rubber hoses harden and crack in extreme cold; PTFE remains flexible. Rubber hoses soften and degrade in high heat; PTFE remains stable.

2. Long-Term Maintenance-Free Operation

Base stations are widely distributed with high maintenance costs, requiring pipeline service life of 10+ years. PTFE material is aging-resistant, weather-resistant, and does not become brittle — significantly outlasting rubber hoses under identical operating conditions.

3. Vibration and Thermal Expansion Absorption

Fans, compressors, and other equipment inside AAU generate continuous vibration. PTFE corrugated tube effectively absorbs vibration, noise, and thermal expansion while compensating for minor connection deviations and eliminating residual stress.

4. Coolant Compatibility

Base station liquid cooling commonly uses ethylene glycol, propylene glycol, fluorinated fluids, and deionized water. PTFE offers excellent acid and chemical resistance — no swelling, no leaching, no degradation.

Customization Options
