Tygon fuel line is a popular choice for fuel systems due to its flexibility, durability, and resistance to many chemicals. However, one common question that arises is whether Tygon fuel line is ethanol resistant. Ethanol, also known as ethyl alcohol, is a common additive in gasoline and can cause damage to certain types of fuel lines. In this blog post, we will delve into the intricacies of Tygon fuel line and its compatibility with ethanol, providing you with the necessary information to make informed decisions about your fuel system.
Understanding Tygon Fuel Line
Tygon fuel line is a type of thermoplastic tubing made from a family of polymers known as “Tygon.” These polymers are characterized by their excellent flexibility, resistance to chemicals, and durability. Tygon fuel line is available in various sizes and formulations, each designed for specific applications.
Ethanol Resistance of Tygon Fuel Line
The ethanol resistance of Tygon fuel line depends on the specific formulation of the tubing. Not all Tygon fuel line is created equal, and some formulations are more resistant to ethanol than others. Here are the different types of Tygon fuel line and their ethanol resistance:
- Tygon R-3603: This formulation is not ethanol resistant and should not be used in applications where ethanol is present.
- Tygon S-54-HL: This formulation is moderately ethanol resistant and can withstand up to 10% ethanol concentration.
- Tygon 2375: This formulation is highly ethanol resistant and can withstand up to 50% ethanol concentration.
Factors Affecting Ethanol Resistance
In addition to the formulation of the tubing, several other factors can affect the ethanol resistance of Tygon fuel line:
- Ethanol Concentration: The higher the ethanol concentration in the fuel, the more likely it is to damage the fuel line.
- Temperature: Ethanol’s effects on Tygon fuel line are amplified at higher temperatures.
- Exposure Time: The longer the fuel line is exposed to ethanol, the greater the potential for damage.
Applications for Ethanol-Resistant Tygon Fuel Line
Tygon 2375, with its excellent ethanol resistance, is suitable for various applications, including:
- Ethanol-blended gasoline fuel systems
- Fuel lines for vehicles using flex-fuel engines
- Industrial processes involving ethanol handling
- Laboratory applications where ethanol is present
Alternatives to Tygon Fuel Line
If you require a fuel line that is resistant to high concentrations of ethanol, there are alternatives to Tygon fuel line available:
- Polyethylene (PE) Fuel Line: PE fuel line is highly resistant to ethanol and can withstand concentrations up to 100%.
- Nylon Fuel Line: Nylon fuel line is also ethanol resistant and can withstand concentrations up to 50%.
- Stainless Steel Fuel Line: Stainless steel fuel line is the most ethanol-resistant option, offering excellent durability and resistance to high temperatures.
Choosing the Right Tygon Fuel Line
When selecting Tygon fuel line for your application, it is essential to consider the expected ethanol concentration, temperature, and exposure time. Choose a formulation that meets your specific requirements and ensure that the fuel line is properly installed and maintained.
Final Note
Tygon fuel line is a versatile and durable option for fuel systems, but its ethanol resistance varies depending on the formulation. By understanding the different types of Tygon fuel line and the factors affecting their ethanol resistance, you can make an informed decision about the best fuel line for your application. Remember, proper installation and maintenance are crucial for ensuring the longevity and performance of your fuel system.
