PA11 vs. PA12: Which Material Should You Choose?
Although PA11 and PA12 are both high-performance polyamide materials, their characteristics make them suitable for somewhat different application requirements.
PA11 Tube
PA11 is particularly attractive for applications requiring a combination of fuel resistance, flexibility, toughness and long-term mechanical performance. It has been widely used in automotive and industrial fluid systems where the tubing may be exposed to fuels, oils, hydraulic fluids or other hydrocarbon-based media.
PA11 is a strong candidate for fuel lines, fuel vapor systems, oil transfer lines and applications where improved flexibility and resistance to environmental stress are important.
PA12 Tube
PA12 offers excellent dimensional stability, low moisture absorption, chemical resistance and flexibility. It is widely used in pneumatic systems, automotive fluid lines, fuel-related applications and industrial equipment.
Its relatively low moisture absorption compared with some other polyamide materials helps maintain stable mechanical and dimensional properties in changing environmental conditions.
The final choice between PA11 and PA12 should be based on the actual medium, operating temperature, pressure, environmental exposure, installation method and required service life.
Materials & Construction
Yozonetech PA tubing is manufactured through controlled extrusion processes to achieve consistent dimensions and stable wall thickness. The tubing can be produced using PA11, PA12 and other polyamide grades according to application requirements.
For oil and fuel-related applications, the material formulation is particularly important. Tubing performance is influenced not only by the nominal polymer type but also by resin grade, additives, processing conditions, wall thickness and the specific fuel or oil being transported.
For demanding applications, the tubing can be developed with customized formulations or constructions to improve resistance to fuel permeation, temperature, pressure, vibration and environmental exposure.
Black tubing is commonly selected for outdoor and automotive applications because it provides improved protection against UV exposure, while natural or transparent options may be selected when visual inspection of the internal medium is beneficial.

Material compatibility testing is recommended for critical fuel-system applications.
Why Use FKM for E30 Gasoline?
Ethanol-blended gasoline creates additional material-selection challenges compared with conventional gasoline.
Ethanol is a polar solvent and can interact differently with elastomers, additives and fuel-system components. Long-term exposure may cause some materials to swell, soften, harden, lose mechanical strength or experience increased fuel permeation.
For this reason, a fuel hose intended for E30 gasoline should not be selected solely based on its appearance or nominal rubber type.
Appropriately formulated FKM can provide a combination of:
- Gasoline resistance
- Hydrocarbon resistance
- Ethanol-blend resistance
- Oil resistance
- High-temperature stability
- Low fuel permeation
- Good aging resistance
- Long-term dimensional stability
For small engines and fuel equipment, the tubing formulation should also be evaluated against the actual fuel mixture, including gasoline additives and storage conditions.
E30 Fuel Compatibility
E30 refers to gasoline containing approximately 30% ethanol and 70% gasoline by volume.
For fuel tubing, ethanol concentration is only one part of the compatibility equation. The actual performance can also be influenced by:
- Gasoline formulation
- Ethanol concentration
- Fuel additives
- Operating temperature
- Fuel pressure
- Continuous or intermittent exposure
- Static immersion versus dynamic flow
- Fuel vapor exposure
- Storage conditions
- Required service life
Yozonetech therefore recommends providing the actual fuel specification when ordering FKM fuel tubing for E30 applications.

Sistema de control de calidad de todo el proceso
Detección de la presión del aire
Nuestra fabricantes de tubos de ptfe utiliza un equipo de prueba de presión de aire con sensor importado totalmente automático. Todos los tubos de PTFE se prueban con 8 kg de presión de aire en el interior y la presión se mantiene durante 60 segundos para evitar todas las fugas de gas.
Detección de impurezas con luz intensa
La fuente de luz de detección se compone de varias fuentes de luz monocromáticas y fuentes de luz compuestas para comprobar diversas impurezas, como las impurezas negras y la parafina, que no son fáciles de encontrar en el proceso de producción de los tubos interiores de PTFE.
Controlador de diámetro láser
Puede controlar de forma continua y precisa los diámetros interior y exterior y las tolerancias durante todo el proceso de producción de tubos de PTFE.
Banco de pruebas de impulsos a alta temperatura
Tubo de ptfe al por mayor es el primer banco de pruebas de impulsos a temperatura media alta (+260°) de la industria, que puede probar la frecuencia de impulsos de tubos de politetrafluoroetileno a diferentes temperaturas medias.
