What You'll Learn
Polyurethane is weaker than traditional fuel lines
Polyurethane is a material that can be used for fuel and oil lines. However, it is weaker than traditional fuel lines, and there are several factors to consider when choosing a fuel line material. Firstly, polyurethane has been observed to have adverse reactions to fuel. It is also prone to becoming brittle and failing after a short period of use. This can pose a safety risk, especially in the event of an accident, as the lines may tear more easily and create a fire hazard.
When compared to traditional fuel lines, polyurethane is less durable and may not be suitable for long-term use. Traditional fuel lines are designed to withstand the high pressures and temperatures associated with fuel systems. They are typically made from materials such as rubber or metal, which have superior strength and resistance to degradation.
Another factor to consider is the compatibility of polyurethane with fuel additives. Some sources suggest that polyurethane has not been extensively tested with modern fuel additives, and there may be potential issues with compatibility. This lack of testing raises concerns about the reliability and safety of using polyurethane fuel lines in certain applications.
Furthermore, the cost of polyurethane fuel lines is relatively high compared to traditional options. While polyurethane hoses are available in auto parts stores, they are often more expensive than standard fuel lines. This is an important consideration, especially for those on a budget or looking for cost-effective solutions.
Lastly, the regulations and approvals surrounding polyurethane fuel lines should be taken into account. In some cases, polyurethane fuel lines may be labelled "For Race or Off-Road Use Only" and may not be approved by organizations such as C.A.R.B. or E.P.A. for street-legal vehicles. It is essential to check the local regulations and requirements before installing any fuel line to ensure compliance and safety.

Polyurethane is more resistant to gasoline than blue fuel lines
Polyurethane is a suitable material for fuel lines, especially in motorcycles and aircraft. However, it is important to note that it is not C.A.R.B. or E.P.A. approved for street-legal vehicles. While polyurethane can be used for fuels and oils, some charts indicate that it may have adverse reactions to fuel additives. It is also weaker than traditional fuel lines, posing a potential fire risk in the event of an accident.
On the other hand, blue fuel lines, which are commonly used in planes and snowmobiles, need to be replaced every 2-3 years before they become brittle and crack. This is a shorter lifespan compared to polyurethane fuel lines, which are known to last longer.
Polyurethane fuel lines are also more resistant to gasoline. While blue fuel lines are reported to last about a year before exhibiting issues, polyurethane is a more durable option. It is important to note that the yellow Tygon line, which is a type of polyurethane fuel line, is highly resistant to gasoline, oil, and ethanol. This makes it a popular choice among pilots and aircraft enthusiasts.
In terms of cost, polyurethane fuel lines are generally more expensive than blue fuel lines. However, their longer lifespan and resistance to gasoline make them a more economical choice in the long run.
When choosing between polyurethane and blue fuel lines, it is important to consider the specific application, regulations, and cost. While polyurethane offers better resistance to gasoline, it may not be suitable for all vehicles due to approval and compatibility concerns.

Polyurethane is extremely resistant to chemical corrosion
Polyurethane is a versatile material with a high resistance to chemical corrosion, which makes it suitable for many industrial applications. Its chemical resistance is dependent on its formulation, and it is important to identify the specific chemicals it will be exposed to in order to tailor the formulation for optimal resistance. Polyurethane's chemical resistance varies, but in general, polyester-type polyurethane demonstrates greater resistance to oils, solvents, and weak acids/bases. On the other hand, polyether-type polyurethane is more resistant to water exposure.
The chemical resistance of polyurethane is rigorously tested by immersing samples in specific chemicals, with typical testing lasting several days at room temperature. Exposure time, temperature, chemical concentration, and aeration are critical factors that influence the outcome. Polyurethane's resistance to a wide range of chemicals has been assessed and graded, including common substances such as acetic acid, acetone, ammonia, ammonium salts, and various oils.
In the context of fuel lines, polyurethane's compatibility with fuels is a point of consideration. While some sources suggest that polyurethane is not suitable for delivering chemicals or petroleum products, others indicate that it can be used with gasoline. It is worth noting that the durability and safety of polyurethane fuel lines have been questioned, with concerns raised about their longevity and potential fire risk in the event of an accident.
To ensure the safe and effective use of polyurethane in fuel lines or any other application, it is crucial to consult manufacturing data and seek expert advice. The chemical resistance of polyurethane can be tailored to specific needs, making it a versatile option for a range of industrial uses. However, the variability in polyurethane formulations underscores the importance of thorough testing and consultation with specialists in the field.

Polyurethane is not suitable for long-term use in fuel tanks
Polyurethane is extremely resistant to chemical corrosion, which makes it perfect for fabrication and as a protective coating to extend the lifespan of oil and gas products. For example, polyurethane coating has been used for over 30 years to protect offshore oil and gas structures. However, this does not mean that polyurethane is suitable for use as a fuel line.
The best alternative to polyurethane fuel lines is Tygon. Tygon is extremely resistant to fuel additives and durable in sunlight. It is also very resistant to gasoline, oil, and ethanol. While Tygon is softer than polyurethane and can kink in tight areas, it is still the best option for fuel lines.
Overall, while polyurethane has its uses in the oil and gas industry, it is not suitable for long-term use in fuel tanks due to its adverse reactions to fuel and weakness compared to traditional fuel lines. Tygon is a much better option for fuel lines and will ensure the safety and durability of your fuel tank.

Polyurethane is cheaper than other hoses
Polyurethane hoses are a cheaper alternative to other hoses, such as rubber. They are made from the same material as the wheels on in-line roller skates, which makes them highly durable. This is especially important if the hose is pulled across rough or sharp surfaces such as rocks, or around stone corners. In comparison, rubber hoses have a softer outer cover that is easier to tear and more susceptible to marks when dragged across surfaces.
Polyurethane hoses also offer greater storage capacity. The rubber hose's thicker cover means less of it can be stored on a hose reel. For example, a standard reel can hold a maximum of 125 feet of polyurethane hose, compared to only 100 feet of rubber hose.
Polyurethane hoses are also more resistant to kinking. When a loop is formed in a rubber hose, its high pliability and flexibility cause it to collapse into a kink. Rubber also retains a high "kink memory", meaning that once kinked, it will repeatedly kink in the same spot. Polyurethane hoses, on the other hand, tend to flip' out of a loop rather than collapse, and they have zero kink memory.
In terms of warranty, polyurethane hoses offer a longer guarantee. ELEY, for instance, backs their polyurethane garden hose with a 10-year, no-leak, no-fail warranty, whereas the longest warranty found for a rubber garden hose was two years.
While polyurethane hoses may be more cost-effective and durable, it is important to consider their limitations. Polyurethane hoses are less pliable and can be more challenging to coil into a circle or wrap uniformly on a hose reel. Additionally, their springier nature may not be desirable in certain applications.
