PTFE hoses

PTFE hoses are hoses that are used for transporting different substances in food, chemical, automotive industries and many more. PTFE hoses are distinguished not only by its exceptional resistance to almost all chemicals, but also by its wide operating temperature range, hygienic properties and longevity. Its properties make it applicable in virtually all industries. PTFE hose is used for transporting steam, hot oil, fuels, paints, adhesives, high-pressure gases, all kinds of chemicals (including very aggressive ones), and due to hygienic reasons also food, cosmetic or pharmaceutical substances. Usually we import this type of hoses only on special order of the customer. Therefore, in most cases, they are not available in the permanent offer.

PTFE hoses - Teflon hoses

What are the properties of PTFE hose?

The key properties of PTFE hose are its high chemical resistance and a wide range of operating temperatures. PTFE hose has several important properties that make it an extremely versatile and attractive technical hose for industry. We list each of them below:

  • very high chemical resistance - it can withstand contact with concentrated (very aggressive) acids and bases, as well as all known solvents without losing its properties; 
  • wide range of permissible operating temperatures - PTFE hoses are suitable for use in temperatures from -70 to 260 degrees Celsius (however, from 130 degrees Celsius there is a gradual decrease in pressure and mechanical properties); 
  • resistance to ageing and weathering - as Teflon does not absorb water, and remains insensitive to ozone, oxygen and UV radiation, PTFE hoses are suitable for use in various conditions, even several decades of regular atmospheric changes will not change the properties of this material; 
  • low coefficient of friction and surface energy - this feature means that substances do not adhere to the walls of the hoses, so the latter have self-cleaning properties and guarantee a high degree of hygiene; 
  • high electrical resistance - this is a property that can be dangerous when transporting a substance that is a poor conductor (in which case an antistatic PTFE blend with graphite is used); 
  • self-extinguishing properties - PTFE hose self-extinguishes when the source of fire is cut off and does not spread fire; 
  • moderate abrasion resistance - this makes it possible to transport moderately abrasive substances.

How are PTFE hoses constructed?

PTFE hoses are constructed in different ways, depending on the type and purpose of the hose. There are four basic varieties:

  • corrugated and smooth-walled PTFE hoses without a braid (not reinforced) - are used for low-pressure operation, in addition (as they have a semi-transparent wall) they allow visual control of the flow of the medium; 
  • smooth-walled braided PTFE hoses (usually made of stainless steel) - have one or two layers of reinforcement and are suitable for use with virtually all media in any industry, which is due to the fact that they combine the versatility of Teflon with the ability to withstand operating pressures of up to 400 bar; 
  • corrugated braided PTFE hoses (made of stainless steel or other materials) - similar to the smooth-walled variety with reinforcement, the only difference is that they are less resistant to pressure, but more flexible; 
  • three-layer hoses (smooth inner PTFE layer, textile braid and/or steel spiral reinforcement, rubber outer layer) - all layers of this type of hose have been permanently connected to the inner Teflon covering, so the product most resembles a standard hose but is mainly used in the chemical industry.

What material versions of PTFE hoses are there?

Among the most popular material versions of PTFE hoses are:

  • Teflon FEP, 
  • PFA/MFA Teflon, 
  • Tefzel (ETFE), 
  • Halar (ECTFE).

Admittedly, the name itself reveals what material PTFE hoses are made of, but, contrary to appearances, there may also be some differences in this respect. This is due to the fact that Teflon copolymers are also used in the production of hoses.

This gives the hoses slightly different properties (for example, better mechanical strength or higher temperature resistance).

FAQ

How to choose the right PTFE industrial hoses?

arrow-up

When you choose PTFE industrial hoses, pay attention first to the working pressure, which is due to the design of the hose. For example, a steel braided PTFE hose will be much more durable in this regard than a non-braided PTFE hose.

Are PTFE hoses suitable for transporting food and pharmaceutical substances?

arrow-up

Yes, PTFE hoses are suitable for transporting food and pharmaceutical substances because they are physiologically inert and have self-cleaning properties. They meet all the requirements necessary for operation in industries where hygiene plays a big role.

What kind of end fittings for PTFE hoses?

arrow-up

For PTFE hoses, we usually use special fittings that were developed just for this type of hose. However, for some varieties of hoses, hydraulic fittings and even some standard (industrial) ones will also work.
