What is PTFE fuel hose | BESTEFLON

PTFE hoses were initially used in automotive sector and quickly became popular. Hoses made from polytetrafluoroethylene perform better than rubber hose in automotive applications due to its high commercial availability and its excellent performance, so their commercial use in automotive is on the rise.

The PTFE hose is a tube composed of an inner PTFE lining and an outer stainless steel braided layer as a protective cover. The PTFE liner is similar to a PTFE tube with an external protective cover, increasing its pressure resistance

PTFE hose characteristics:

Chemical inert

lLow permeability

lLowest coefficient of friction

lLight weight





lWeathering / aging resistance

lSolvent resistant

Excellent electrical properties

PTFE hose core options:

100 % Virgin PTFE inner core

Our virgin PTFE inner tube is made of 100% PTFE resin without any pigment or additive.

Conductive (Anti-static) PTFE inner core

Statically dissipative or fully conductive for the dissipative elimination of static charges affecting combustible fluid transfer. To run with E85 and Ethanol, or Methanol Fuel, conductive PTFE inner core is necessary.

PTFE fuel hose options:

PTFE hose with stainless steel braided - One of the most popular PTFE fuel hose

PTFE hose with double stainless steel braided - To increase the pressure for certain applications

PTFE hose with stainless steel braided and black Nylon covered - Good protect to stainless steel layer and abrasion resistance

PTFE hose with stainless steel braided and PVC coated - Good protect to stainless steel layer and make it look fancier to your vehicle

Advantages of PTFE fuel hose compared with rubber fuel hose:

Polytetrafluoroethylene (or polytetrafluoroethylene) hose is an excellent substitute for rubber hose. With the right manufacturing and housing, they can be very durable and very simple to install into the system. Although they do not provide the same elastic range made of rubber, PTFE hoses are highly resistant to most chemicals, and they do not often release fumes, which is important for any kind of enclosed space. This chemical resistance also means that PTFE hoses decompose much slower than rubber hoses.

 The surface friction of PTFE is also lower than that of rubber, which means that the flow rate can be improved by using a PTFE hose. Although rubber is easily decomposed at extreme temperatures, PTFE is resistant to high temperatures, making it an ideal choice for various industries.

 The surface friction of PTFE is also less than that of rubber, which means that the use of PTFE hose can improve the flow rate. Rubber is easy to decompose at extreme temperatures, and PTFE is resistant to high temperatures, making it an ideal choice for various industries.

 First, the PTFE hose acts as a vapor barrier to prevent gasoline odors from leaking into the garage or store and burning when your ride rests.

 Second, the PTFE-lined hose has the highest chemical resistance and supports a bunch of automotive fluids, which is not possible with ordinary rubber. The most common is that the blended gasoline contains ethanol. Ordinary rubber hoses decompose when they come into contact with this gasoline, and eventually decompose to the point where they may begin to leak or inject fuel-which is very dangerous.

 Third, the PTFE lined hose has very high temperature resistance-in fact, the operating temperature range of the hose sold by our fuel hose is -60 degrees Celsius to +200 degrees Celsius. It is very suitable to open the water pipe on your sports car.

 Fourth, our fuel hose PTFE lined hose has a very high working pressure, again ensuring that you can use it for all types of automotive and hot rod applications. AN6 size is suitable for 2500PSI, AN8 size is suitable for 2000psi-even for the most demanding applications, there is enough pressure.

What Fuel Line Do You Need to run with E85 and Ethanol, or Methanol Fuel?

The use of ethanol and methanol fuels has become more and more popular in recent years, especially with the rise of high-horsepower turbocharged supercharged engines. E85 or ethanol has proven to be a cost-effective fuel that can provide demanding applications with octane rating and power potential. In addition, it can also produce a cooling effect on the intake air.

However, ethanol is corrosive, in some cases it will form a gel-like substance, and may damage fuel system components, otherwise it will not be affected by gasoline and racing gas.

A special fuel filter must be used. Of course you have to make sure that your fuel pump is compatible, but what about the fuel line?

The PTFE hose can be provided with stainless steel braid and black coating. This conductive style PTFE uses an outer braid and an inner PTFE liner, which is highly resistant to chemical substances and thermal decomposition. Conductive wire is important to use and consider whether to choose the PTFE option, because the electrostatic charge generated by the fuel flow will actually arc/burn and cause the charge, which will cause a fire.

PTFE is more difficult to assemble, but its life is not easily affected by temperature and pressure. This makes it an excellent choice for corrosive fuels, as well as power steering lines, turbine oil lines, etc. For these reasons, it is also a good choice for E85 and ethanol fuels and methanol
