PVC and other plastics are not well suited for usage with fuel gas or kerosene due to their composition. In high-temperature conditions, PVC and other polymers deform readily and may leak or break.
Will PVC pipe be harmed by gas?
2) PVC and fuel, particularly gasoline, are a terrible mix because gasoline dissolves PVC. You may get 3/8″ gasoline hose from any auto supply store and rest assured that it will not cause any issues.
Is it possible to use plastic pipe for gasoline?
The most extensively utilized plastic piping material for natural gas distribution is polyethylene (PE) gas piping. PE’s inertness to both the external soil environment and natural gas has been widely demonstrated.
What kind of plastic can be used to store gasoline?
The extremely combustible fumes created by the gas are one of the most serious hazards and risks related with gasoline storage. The most serious danger in the case of oil is a spill. Plastics made from petrochemicals and oil help to ease these key difficulties. High-density polyethylene (HDPE) is a strong plastic that is often used to produce plastic gas cans and barrels because it insulates the contents and protects the gas from the heat of the environment. It’s also antimicrobial and rust-resistant, which means nothing will leak out of corroded portions.
Many modern oil and gas barrels have a “double-wall” structure that combines plastic and steel. The inside layer is made of petrochemical polymers to keep it liquid-tight and well insulated, while the exterior layer is made of steel to deter theft and help maintain internal pressure. They work together to keep your gasoline and oil safe and ready to use when you need it.
Is PVC resistant to gasoline?
Many alcohols, fats, oils, and aromatic free gasoline are resistant to PVC. Most common corrosive agents, such as inorganic acids, alkalis, and salts, are also resistant to it. PVC should not be utilized with esters, ketones, ethers, aromatic or chlorinated hydrocarbons, or aromatic or chlorinated hydrocarbons. These compounds will seep into PVC, causing swelling and a loss in tensile strength.
Considerations for PVC Pipe
PVC pipes are completely unaffected by soil and water pollutants when used for standard water supply. Toxic resistance is only likely to become an issue if they are employed in unique locations or to transport chemical compounds. Health regulations should be followed for applications that are classified as food conveyance or storage. On the use of PVC pipes, specific guidance should be sought. PVC-O is chemically equivalent to conventional PVC-U, however rates of attack may differ, making it unsuitable for use in chemical environments or for chemical conveyance. PVC-M is intended to operate chemically similarly to regular PVC-U in most conditions. However, if concentrated chemicals will be in contact with PVC-M for an extended period of time or if elevated temperatures are expected, preliminary testing to evaluate the material’s appropriateness is required.
Sewage Discharges
Anything that is normally contained in sewage effluent will have no effect on PVC. However, most chemicals are more likely to harm the rubber ring (common to all current pipe systems) than the PVC pipe if an unauthorized discharge is performed. PVC can be safely utilized in any municipal sewerage network, including locations accepting industrial wastewater, due to contemporary pollution controls on sewage discharges.
Chemical Resistance of Joints
It’s crucial not to disregard the effect of the environment on the jointing materials while assessing the performance of pipe materials in chemical settings. Solvent cement joints can be utilized in almost any situation where PVC pipe is suitable. The rubber ring, on the other hand, may require special attention.
Rubbers can be attacked chemically in two ways. Swelling can develop as a result of chemical absorption. It may become weaker and more vulnerable to mechanical harm as a result of this. On the other hand, it might help keep the sealing force in place. Alternatively, the chemical attack could cause the rubber to degrade or modify its chemical structure. Chemical concentration, temperature, rubber compounding, and component dimensions all have an impact on both types of attacks. The attack’s severity may also be influenced by the amount of surface area exposed to the environment.
For information on the chemical resistance of rubber compounds widely used in pipe seals, see Chemical Resistance of Elastomers.
Chemical Resistance Table
The information presented here is based on the findings of immersion tests performed on specimens in the absence of any stress. It may be necessary to conduct additional tests to examine the behavior of pipes and fittings under internal pressure or other stressors if the preliminary categorization suggests high or limited resistance.
Variations in chemical component analysis, as well as operating circumstances (pressure and temperature), can greatly alter the real chemical resistance of materials in comparison to the given value in this chart.
It is important to note that these ratings are merely meant to serve as a starting point for learning about the material to be chosen. They may not cover the precise use in question, and the effects of changing temperatures or concentrations may require testing under specific conditions.

What kind of gasoline hose can I use?
Standard neoprene fuel hose can be used for fuel, PCV and EEC systems on all vehicles where working pressures are under 50 psi or vacuum ratings are under 24-in. Hg for 7/16-inch and smaller inside-diameter sizes (10-in. Hg for 1/2-inch diameter hose).
Is it possible to use black pipe for gasoline?
Pipes are needed to supply water and gas to houses and businesses. Stoves, water heaters, furnaces, and other appliances run on gas. Water is both necessary and obvious. Black pipe and galvanized pipe are the two most prevalent types of steel pipe used to transport water and gas. Homeowners and even some professionals are often perplexed as to where and when to use these steel pipes.
Galvanized steel pipe has a zinc coating applied to it to make it more corrosion resistant. Galvanized pipe is mostly used to bring water to homes and structures. The zinc also helps to prevent mineral deposits from clogging the water line.
Because it is uncoated, black steel pipe differs from galvanized pipe. The black color is due to the iron oxide that formed on the surface during production. Black steel pipe’s principal function is to transport natural gas into homes and businesses. The pipe has no seams, making it a stronger and safer pipe for transporting gas. Because black steel pipe is more fire resistant than galvanized pipe, it is also utilized for fire sprinkler systems.
In summary:
- Steel is used to make black and galvanized pipe.
- Black pipe does not have a zinc coating, whereas galvanized pipe does.
- Galvanized pipe is great for transporting water but not for transporting gas.
- Because of the zinc coating, galvanized pipe is more expensive.
- Galvanized pipe is more resistant to corrosion.
Because of the galvanized coating, you should not use galvanized pipe for gas. Galvanized steel bits will flake off over time and block your gas regulators and burner units.
If you mix galvanized and black iron, corrosion will be accelerated where they come into contact.
What is the best fuel line material?
Fuel lines are built of a variety of materials, each with its own set of advantages and disadvantages. The majority of fuel lines are reinforced rubber. Fuel lines should be made of this material since it prevents kinking and cracking. Make sure you choose a fuel line that can handle both vapor and liquid fuel. Stainless steel, plastic, steel coated with zinc, and nylon are some of the other materials used in gasoline lines. It is critical to read several reviews and learn how a specific fuel line performed for other users before making a purchase.
Q. What Is The Best Material For Fuel Lines?
The ideal gasoline line material is determined by your requirements. Polytetrafluoroethylene, or PTFE, is the ideal material for gasoline lines. Teflon is a type of plastic that is used to make PTFE fuel lines. This gasoline line material is resilient to degenerative fuel effects that might cause vapor barriers to form. It does, however, have drawbacks, just like everything else. Because it is inelastic, it is prone to kinking. However, if you use a proper bending tool while producing bends and curves, you can avoid this.
Q. Can I Replace Metal Fuel Lines With Rubber?
If your metal gasoline lines have rusted and begun to leak, you should repair them immediately to minimize further damage. Yes, rubber fuel lines can be used in place of metal gasoline lines. Some individuals prefer to repair only the rusty portion of the gasoline line, however it is more prudent to replace the entire fuel line. Rubber components in fuel lines are strengthened and can withstand high pressure from current injection systems. Rubber gasoline lines are also quite sturdy and will last a long time.
Q. Can Fuel Line Be Submerged In Fuel?
The sort of fuel line you wish to submerge in petrol will determine how long it takes. Fuel lines can be submersible or non-submersible. Even when buried in fuel, submersible fuel lines can survive. Non-submersible gasoline lines, on the other hand, are only meant to be used from the inside. As a result, depending on how and where you intend to use the fuel line, always check whether it is submersible or non-submersible before purchasing it.
Q. Can Vinyl Tubing Be Used For Fuel Line?
Vinyl tubing isn’t the ideal fuel line material unless it’s specifically designed for it. Gasoline, ethanol, and other hydrocarbons should not be transported in plain vinyl tubing. After some time, this tubing turns yellow. After conveying fuel, vinyl tubing becomes rigid and brittle. Only use Vinyl Tubing for fuel lines that are specifically designed for the job.
Q. Can Copper Be Used For Fuel Lines?
Another fuel line material available on the market is copper. It is one of the most appealing materials for fuel lines. It establishes a long-term gasoline or oil line and connection. As a result, copper fuel lines are acceptable. However, because new copper gasoline lines are easier to install than old tubing, it is recommended to utilize them instead of old tubing. If you’re working with old copper tubing, heat it to soften it and make it easier to bend. Some copper gasoline lines can be bent nicely with time and patience, but you’ll require bending equipment in your mechanic toolbox if this isn’t the case.
Q. Can You Replace Steel Fuel Lines With Nylon?
Yes, nylon fuel lines can be used in place of steel gasoline lines. Many people prefer nylon gasoline lines because they are more cost-effective. They’re also quite adaptable and simple to set up. Even without bending tools, some nylon fuel line materials may generate elegant bends and curves. These fuel lines are available in various lengths and can be used to replace a single segment or the full fuel line.
Is PVC hose resistant to oil?
Thermoplastic materials such as PVC and polyurethane can be shaped into a variety of shapes, including tubing and reinforced hose. Both materials have a wide range of uses. However, depending on parameters such as temperature, chemical compatibility, and the usage of plasticizers, one product may perform better in a given application than the other. This article explores the advantages, disadvantages, and widespread applications of each material as they relate to goods that are widely available in a range of industries.
PVC
Although no single form of plastic tubing can handle all applications, PVC (polyvinyl chloride) tubing covers one of the broadest variety of applications of any type of plastic. Chemical and corrosion resistance, good abrasion and wear resistance, rubber-like flexibility, visual contact with the flow (with clear styles), and superior flow characteristics are all features of flexible PVC tubing. These characteristics, as well as varied construction alternatives such as wire, spiral, or braid reinforcement or unreinforced tubing, and different formulas (industrial, fuel and oil grade, 3-A, FDA, NSF, USP Class VI), make PVC appealing for a wide range of applications. (See Illustration 1)
Chemical processing, waste product lines, viscous fluid handling, wet or dry food handling, beverage transfer, dairy processing, granular material conveyance, air and gas supply, vacuum lines, pump discharge, spray systems, small engine fuel lines, protective jacketing, potable water, and irrigation systems are just a few examples.
PVC has a number of drawbacks, including the potential for it to harden and become less malleable when certain fluids, such as powerful acids and alkalis, are passed through it. PVC tubing does not react well with fuels and oils, hardening and cracking the tubing. For fuel and oil applications, such as those involving small engines, special PVC formulations are available.
Medical, industrial, laboratory, chemical, food, beverage, and dairy, appliance, cleaning apparatus, pool and spa, and energy are some of the industries that employ PVC tubing.
Polyurethane
Polyurethane, often known as PU, PUR, or TPU, is a material that combines the greatest qualities of both plastic and rubber. It has high elongation values (stretchability) similar to rubber and greater abrasion resistance to PVC. Polyurethane is a naturally flexible material that does not require the addition of any additives to maintain its flexural capabilities.
Polyurethane distinguishes itself from other thermoplastics by combining outstanding chemical resistance with great weathering qualities. Polyurethane is more resistant to pressure and vacuum applications than PVC or rubber of comparable sizes. It also withstands cuts better than most other thermoplastics. (Refer to Figure 2)
What happens to plastic when it’s exposed to gasoline?
Certain types of plastic can disintegrate in gasoline, resulting in more spillage. If the gas comes into contact with a spark, it might start a life-threatening fire. For storing flammable substances, officials recommend using a Transportation Department-approved container with an appropriate lid.
