PPR Pipes VS PEX Pipes

When it comes to piping systems, two popular choices are PPR and PEX pipes. They are both used in plumbing systems, but each have their own unique characteristics. PPR pipes are commonly used in residential and commercial buildings for hot and cold water systems, while PEX pipes are used in residential and commercial buildings for hot and cold water systems as well as radiant heating systems. In this article, we will compare them and highlight their differences.

PPR pipes

PPR stands for polypropylene random copolymer. It is a type of plastic that is commonly used for pipes and fittings in plumbing systems. PPR pipes are known for their durability and resistance to high temperatures. They have a maximum operating temperature of 90 degrees Celsius, which makes them ideal for hot water systems. PPR pipes are also easy to install, as they come with a range of fittings that can be easily connected together.

PEX pipes

PEX stands for cross-linked polyethylene. It is a flexible plastic tubing that is commonly used in residential and commercial plumbing systems. They are known for their flexibility and ability to bend and curve around obstacles. They are also resistant to corrosion and scale buildup, which makes them ideal for use in areas with hard water. The pipes have a maximum operating temperature of 82 degrees Celsius, which makes them suitable for hot water systems and radiant heating systems.



The first major difference between them is their material. The former is made of polypropylene, while the PEX pipe is made of fused PVC. The PPR pipe has greater strength, which makes it less flexible. PEX pipe is flexible, so it is easy to install and can be adjusted according to the shape of the installation space.

Highest Working Temperature

The highest use temperature of PPR tubing is higher. It can withstand temperatures up to 90 degrees Celsius, while PEX tubing can withstand temperatures up to 82 degrees Celsius. This means that PPR tubing is more suitable for hot water systems.


PPR tubing is easier to install. It is equipped with a series of accessories that can be easily joined together, and is more rigid, allowing easy straight-line installation. While PEX tubing requires special tools to connect them together, it is also more difficult to bend and twist. over obstacle,


PPR tubing is generally more expensive. It is more durable, has a longer service life, resulting in a higher cost. PEX tubing is cheaper, but has a shorter service life and may require more frequent replacement.


In short, PPR and PEX tubing are popular choices for plumbing systems. The former has greater toughness, the highest working temperature, and easier installation, but the price is more expensive. The latter is more flexible, more easy to use, and the cost is lower, but the highest The working temperature is lower and the service life is shorter. When selecting pipe, it is important to evaluate your needs and select the pipe best suited for your specific application.
