Why use PTFE Lined Hose For Fuel? | BESTEFLON

  PTFE hose 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.

  What is PTFE hose?

  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, as automotive uses for PTFE hose.

What is the properties of PTFE hose?

  Chemical inert, compatible for most kinds of fuels

  Low permeability

  Lowest coefficient of friction

  Light weight

  Non-sticky

  Non-wettingl

  Non-flammable

  Weathering / aging resistance

  Excellent electrical properties

PTFE lined fuel hose - types:

  Virgin PTFE fuel hose

The hose core for virgin PTFE fuel hose is made of 100% PTFE resin without any pigment or additive.

Conductive (Anti-static) PTFE fuel hose

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 hose for fuel - options:

  PTFE braided hose with single SS layer - One of the most popular PTFE fuel hose

  PTFE braided hose with double SS layer - To increase the pressure for certain applications

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

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

Compared with rubber fuel hose, why choose PTFE fuel hose?

  PTFE fuel lines are 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 fuel hose in racing car.

  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 PTFE hose has a very high working pressure, again ensuring that you can use it for all types of automotive 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
