Ethanol's Impact on PVC NBR Fuel Lines
Ethanol, a common additive in gasoline, has a significant impact on the performance and longevity of fuel lines, particularly those made from PVC (polyvinyl chloride) and NBR (nitrile butadiene rubber). When using ethanol-free gasoline, the compatibility of these materials becomes a critical consideration for vehicle owners and mechanics.
PVC fuel lines are known for their durability and resistance to chemicals, making them a popular choice for fuel delivery systems. However, when exposed to ethanol, PVC can undergo a process called hydrolysis, where the ethanol's oxygen atoms react with the PVC's chlorine atoms, leading to the breakdown of the material. This reaction can cause the fuel lines to become brittle, crack, and eventually fail, resulting in fuel leaks and potential engine damage.
NBR, on the other hand, is a synthetic rubber commonly used in fuel lines due to its flexibility and resistance to fuel degradation. While NBR is generally more compatible with ethanol than PVC, it is not entirely immune to its effects. Ethanol can cause NBR to swell and lose its shape, leading to reduced flexibility and potential cracking over time. This can result in fuel leaks and decreased performance, especially in high-temperature environments.
