Vinyl Vs Polyurethane Fuel Line

Late model efi cars now all use a fluoroelastomer fuel line that looks plastic but is actually a material called polytetrafluoroethylene ptfe.

Vinyl vs polyurethane fuel line.

Urethanes are formed by combining urethane based resins and urethane based hardeners which are composed of hydroxyl or amine components. As nouns the difference between vinyl and polyurethane is that vinyl is vinyl while polyurethane is polyurethane any of various polymeric resins containing urethane links. Mainly this was not for pressure related issues but instead for emission reasons where rubber fuel line allowed fuel to vaporize through the line and into the atmosphere. Polyurethane hose can also handle much lower temperatures.

Combining good chemical resistance with excellent weathering characteristics sets polyurethane apart from most other thermoplastics.

It should however not be used on coolant systems oil systems or fuel injection systems that produce pressures higher than 50 psi. Both materials are useful in numerous applications. As a result the terms urethane and polyurethane are used interchangeably. It has exceptional resistance to most gasoline oils kerosene and other petroleum based chemicals making pu tubing and hose an ideal choice for fuel lines although additives in today s gasoline and petroleum.

Fuel line is a petroleum resistant nitrile tube with a covering that resists weathering ozone and heat and can be used for ethanol laced fuels and diesel fuel. Will it be alright to used it to connect gas tank to the carburetor. 2002 jetta sedan alh 01m. Esp retrofit custom greasecar.

Polyurethane tubing is commonly used in medium pressure applications such as solid liquid and gaseous dispensing and fuel line and wire abrasion protection. Polyurethane hose pu polyurethane hose provides the solution where pvc struggles featuring excellent resistance to most petroleum based chemicals. When the resins and hardeners are combined they form a chemical reaction which results in a. Nylon is a common choice in hydraulic lines and refrigeration air conditioning systems fuel and oil transfer and chemical transport.

This makes it an ideal choice for use in most fuel lines although testing might be necessary in some cases.
