Can You Use PVC for Air Lines?
Proper piping in compressed air systems is crucial for your business's operational efficiency and safety. While some might consider polyvinyl chloride (PVC) because of its durability, versatility and affordability, it's not the best piping for compressed air.
So if I can’t use PVC, what type of piping should I use for my compressed air?
Both stainless steel and aluminum piping are highly recommended for compressed air transportation. Stainless steel piping is strong, durable and will not rust. Aluminum piping is light-weight, easy to handle, non-corrosive and cost-efficient. AirNet offers both stainless and aluminum solutions that are easy to install and comes backed with a 10-year warranty.
Although it may seem like a cheap, easy option to install PVC for transporting your compressed air, the high risk of fines, damage, injury and even death greatly outweigh the perceived benefits of using PVC pipe.
Safety Concerns With Using PVC for Air Lines
PVC is a synthetic polymer used for pipes to transport liquids. When PVC piping leaks when transporting water, the pipe just splits and releases water at a lower pressure. PVC pipe in any compressed air application is hazardous.
However, the situation is different with air, which is compressible. PVC is not designed for high-pressure systems. Compressed air inside the piping can swell and burst, leading to catastrophic failure.
Using PVC pipe in any compressed air application is extremely dangerous and not recommended by multiple associations and manufacturers.

How many times a month do I have to drain the water from my compressor?
Every time you operate your air compressor, the atmospheric air that fills your compressor tank contains a certain percentage of water vapor, and if left alone, this water vapor can accumulate and damage the internal structure of your air compressor.
When do you need to change your air compressor air filter?
An air compressor is a big purchase for any business. It is visibly important to properly maintain the air compressor and filter elements to protect that investment. An unclean air or oil filter causes the compressor to run less efficiently.
What Does Air Treatment Mean?
Investing in air treatment is a sort of insurance of compressed air system. Air treatment extends air compressor’s lifespan and saves you money in the long run.
Pressure Rating Issues
Most PVC pipes are rated for pressure ranging from 300 pounds per square inch (PSI) to 600 PSI, while industrial compressed air systems are pressurized between 100 PSI and 125 PSI. Based on this information, you might think PVC pipes can handle compressed air. However, the PSI rating is:
- For the pipe only, not including seals and joints. PVC pipes fail at the joints because most PVC adhesives are not compatible with air compressor lubricants.
- Temperature-dependent. PVC pipelines are more prone to brittleness and shattering if the temperature drops below freezing point.
- Cut in half when it drops at extremely high temperatures. The maximum rated temperature of most PVC piping is 140 degrees Fahrenheit. Once the air inside the pipe reaches 110 degrees Fahrenheit, the pipe rating is cut in half, leading to a higher risk of an explosion.
Health Risks
When PVC is under pressure or heated, harmful chemicals are at risk of explosion and contamination. If it is burned improperly, it can also emit a highly toxic compound called dioxins.
Wear and Tear
PVC pipes become brittle over time, and the deterioration of the pipes increases the chance of a leak or explosion.
What Types of Piping Are Suitable for Compressed Air?
For safety and durability, manufacturers and multiple associations recommend either:
- Stainless steel air compressor pipes: Stainless steel is strong, durable and rust-resistant.
- Aluminum piping: Aluminum is lightweight and cost-efficient, and its noncorrosive properties ensure durability and longevity.
