PTFE hoses: an advanced solution for demanding industrial applications

PTFE hoses are designed for industrial applications where maximum chemical resistance, thermal stability and long-term reliability are required. Manufactured from polytetrafluoroethylene, these hoses are commonly known in the industry as PTFE (Teflon) hoses and are used when other materials cannot provide sufficient guarantees.

Thanks to their unique properties, PTFE hoses are used in critical industrial processes, where system safety and fluid integrity are determining factors.

What PTFE is and why it is a key material in industrial hoses

PTFE is a technical polymer renowned for its exceptional behaviour against chemical products, extreme temperatures and ageing. In the form of a PTFE (Teflon) hose, this material provides an almost completely inert and non-stick internal surface.

These characteristics make PTFE hoses particularly suitable for conveying aggressive, sensitive or high-purity fluids, where contamination or material degradation is not acceptable.

Technical properties of PTFE hoses

PTFE hoses stand out for a set of technical properties that place them among the most advanced solutions for industrial fluid transfer:

• Wide operating temperature range.
• Excellent chemical resistance to acids, solvents and corrosive products.
• Low internal friction, facilitating smooth fluid flow.
• High thermal and dimensional stability.
• Long service life, even in continuous processes.

These characteristics make PTFE (Teflon) hoses a safe and durable option for demanding applications.

Construction of an industrial PTFE hose

The construction of an industrial PTFE hose is based on an inner PTFE tube, which can be smooth or convoluted, depending on the required flexibility. An external reinforcement is added over this tube, typically in the form of stainless steel braids.

The number of braids and the construction type directly influence the allowable pressure, bend radius and mechanical behaviour of the hose in service.

Types of PTFE hoses according to design and application

PTFE hoses can be supplied in different configurations to suit the requirements of each industrial process:

• Smooth-bore PTFE hoses, designed to minimise pressure loss.
• Convoluted PTFE hoses, offering increased flexibility.
• PTFE (Teflon) hoses with one or two reinforcing braids.
• Specific configurations according to pressure, temperature or regulatory requirements.

Industrial applications of PTFE hoses

PTFE hoses are used in numerous industrial sectors where reliability and chemical compatibility are essential:

• Chemical and petrochemical industry.
• Processes involving highly corrosive products.
• Pharmaceutical and food applications.
• High-temperature or high-pressure systems.
• Transfer of critical fluids.

PTFE (Teflon) hoses for chemical and critical applications

In chemical applications, PTFE (Teflon) hoses provide a decisive advantage: their ability to handle a wide range of products without reacting or degrading.

This chemical stability helps maintain fluid purity, reduce contamination risks and ensure safe operation even in particularly aggressive processes.

How to choose the right PTFE hose

Selecting a PTFE hose should be based on a prior technical assessment. Some of the key factors to consider include:

• Type of fluid and its chemical aggressiveness.
• Operating temperature range.
• Service pressure and possible pressure peaks.
• Required flexibility and bend radius.
• Regulatory requirements of the process.

Specialised technical advice makes it possible to select the safest and most efficient solution.

Connections, fittings and assemblies for PTFE hoses

In installations using PTFE hoses, the correct choice of fittings, flanges and connections is just as important as the hose itself. An inadequate assembly can compromise overall system safety.

For this reason, PTFE (Teflon) hoses should be supplied as part of a complete solution, with connections adapted to the specific application.

Safety, standards and service reliability

PTFE hoses are commonly used in regulated industrial environments, where safety and traceability are essential requirements.

Their long-term stable behaviour helps reduce risks and maintain continuous, reliable operation of industrial processes.
