The following are the common technical parameters of PTFE fuel hose
The technical parameters of PTFE fuel hose mainly involve material performance, size, pressure resistance, temperature range and other aspects.
1.Material
Inner layer: polytetrafluoroethylene (PTFE), with strong chemical stability, corrosion resistance and high temperature resistance.
Outer layer: usually reinforced with stainless steel wire braid (or Kevlar Fiber Braid), providing high strength and compressive resistance. The outer layer may also have PVC or other protective layers to prevent external wear and contamination.
2. Temperature range
Operating temperature: the operating temperature of PTFE fuel hose is usually between -65° Cand 260 ° C. Some types of PTFE hoses can be used at higher temperatures (up to 300° C), but the appropriate type needs to be selected according to the specific application scenario.
Short time temperature resistance: some PTFE fuel hoses can withstand temperatures up to 260 ° C in a short time.
3. Withstand voltage performance
Working pressure: the working pressure is usually between 1500 psi (about 103 bar) and 3000 psi (about 207 bar), depending on the diameter of the PTFE fuel hose and the outer reinforcement material. Some models can withstand higher pressures and are suitable for high-pressure fuel delivery systems.
Burst pressure: the burst pressure of PTFE fuel hose is usually much higher than the working pressure, which is usually more than 3 times of the working pressure.
4. Inner diameter and outer diameter
Inner diameter: the inner diameter ptfe fuel line hose usually ranges from 3 mm to 25 mm. The common inner diameters are 5 mm, 6 mm, 8 mm, 10 mm, 12 mm, 16 mm and 19 mm.
Outer diameter: the outer diameter depends on the wall thickness of the inner PTFE hose and the use of the outer woven material. Common outside diameters range from 10 mm to 30 mm.
For example, common PTFE fuel hoses of 6 an PTFE fuel line, An8, An10 and other specifications have inner diameters corresponding to 3/8 inch, 1/2 inch and 5/8 inch respectively.
5. Chemical corrosion resistance
PTFE fuel hose has strong corrosion resistance to almost all common fuels, chemicals, solvents, greases and gases. It is not affected by acid, alkali, oil, gas, alcohol, etc., and is widely used in automotive, aerospace, chemical industry and other fields.
6. Bending radius
The minimum bending radius of PTFE fuel hose is usually between 3 times the inner diameter and 5 times the inner diameter. For example, PTFE fuel hose with 6 mm inner diameter has a minimum bending radius of 18 mm to 30 mm. For larger diameter hoses, the bending radius needs to be larger.
7. Abrasion resistance
PTFE material has very low friction coefficient, which makes it have low wear in the transmission of high velocity fluid. The outer braided reinforcement structure of PTFE fuel hose (such as stainless steel braid or Kevlar Braid) improves its wear resistance and can adapt to the worse working environment in vehicles or machines.
8. Quality standards and certification
ISO 9001 certification: ensure the quality control and product consistency in the production process.
SAE J1401:Some PTFE fuel hoses meet this standard and are suitable for the delivery system of gasoline, diesel and other fuels.
9. Special functions
UV protection: some PTFE fuel hoses adopt special coatings to prevent hose aging caused by UV radiation.
Anti static function: in some high-performance systems, PTFE fuel hoses can have anti-static function to prevent potential hazards caused by electrostatic accumulation.
10. Scope of application
Automotive and racing applications: it is suitable for fuel hoses of racing cars and high-performance vehicles because of its excellent compression resistance and high temperature resistance.
For aircraft fuel system, it can withstand extremely high temperature and pressure.
Industrial chemical transportation: widely used in chemical, pharmaceutical, food and other industries, it can safely transport all kinds of chemical substances and corrosive fluids.

FAQ About PTFE Fuel Line
PTFE (Polytetrafluoroethylene) fuel lines are commonly used in various high-performance applications due to their durability, chemical resistance, and temperature stability. PTFE is a fluoropolymer known for its non-stick properties and resistance to corrosion, making it ideal for transporting fuels, oils, and other chemicals in automotive, aviation, and industrial settings.
What material is used for PTFE fuel line?
PTFE fuel lines are made from Polytetrafluoroethylene (PTFE), a high-performance fluoropolymer known for its exceptional chemical resistance, thermal stability, and non-stick properties. To enhance durability and performance, the PTFE core is often reinforced with a stainless steel or nylon braided outer layer. This construction provides superior resistance to high pressure, extreme temperatures, and compatibility with a wide range of fuels, including gasoline, diesel, E85, and biofuels.
Inner is Polytetrafluoroethylene (PTFE)
Outer is stainless steel braid/PU /PVC/Silicone/Glass Fiber/Nylon/EPDM/Polyester/Aramid Fiber
