Understanding PEX pipe sizes and thicknesses

PEX pipes are a popular choice for plumbing applications due to their flexibility, durability, and cost-effectiveness. However, understanding the different sizes and thicknesses of PEX pipes can be confusing, especially for those who are new to plumbing. In this blog post, we will discuss the different sizes and thicknesses of PEX pipes and how to choose the right size for your plumbing project.

PEX Pipe Sizes

PEX pipes come in three main sizes: 3/8-inch, 1/2-inch, and 3/4-inch. These sizes refer to the outside diameter of the pipe. The most common size used in residential plumbing is 1/2-inch PEX, which is suitable for most applications. The 3/4-inch size is typically used for larger commercial applications, such as high-rise buildings or large industrial projects. The 3/8-inch size is less common and is typically used for small projects or in areas where space is limited.

It’s important to note that PEX pipes are not measured by their internal diameter like other types of pipes. This is because PEX pipes have a thinner wall thickness than traditional pipes, which allows for a larger internal diameter.

PEX pipes come in two different thicknesses: PEX-A and PEX-B. PEX-A pipes are cross-linked using a peroxide process, which results in a more uniform and consistent product. PEX-A pipes are more flexible and resistant to damage from freezing, making them a good choice for cold weather climates. They are also more expensive than PEX-B pipes.

PEX-B pipes are cross-linked using a silane process and are less expensive than PEX-A pipes. However, they are also less flexible and more prone to damage from freezing. PEX-B pipes are a good choice for warm weather climates or for indoor plumbing applications where freezing is not a concern.

When choosing the thickness of your PEX pipes, it’s important to consider the specific needs of your plumbing project. If you live in an area with cold winters, you may want to consider using PEX-A pipes to prevent damage from freezing. On the other hand, if you live in a warm climate or are working on an indoor plumbing project, PEX-B pipes may be a more cost-effective option.

PEX Pipe Color

PEX pipes come in a variety of colors, but these colors do not indicate the size or thickness of the pipe. Instead, the colors are used to identify the specific type of pipe and its intended use. The most common colors for PEX pipes are red, blue, and white.

Red PEX pipes are typically used for hot water lines, while blue PEX pipes are used for cold water lines. White PEX pipes are used for both hot and cold water lines and are the most common color used in residential plumbing installations.

It’s important to note that some PEX pipes may be labeled as “oxygen barrier” or “non-oxygen barrier.” Oxygen barrier PEX pipes have a layer of oxygen-resistant material that prevents the diffusion of oxygen into the water supply. These pipes are typically used in radiant heating systems or in areas with high levels of dissolved oxygen in the water supply.

Choosing the Right PEX Pipe Size and Thickness

Choosing the right size and thickness of PEX pipes is an important step in any plumbing project. Here are some factors to consider when selecting your PEX pipes:

• Water pressure: The size and thickness of your PEX pipes should be able to handle the water pressure of your plumbing system. If you have high water pressure, you may want to consider using thicker PEX pipes.
• Length of pipe runs: Longer pipe runs may require larger PEX pipe sizes to ensure adequate water flow.
• Climate: If you live in an area with cold winters, it’s important to choose PEX-A pipes that can resist freezing and prevent damage to your plumbing system.

• Budget: PEX-A pipes are more expensive than PEX-B pipes, so you may want to consider your budget when choosing the thickness of your PEX pipes.
• Intended use: Red PEX pipes are intended for hot water lines, blue PEX pipes are intended for cold water lines, and white PEX pipes are intended for both hot and cold water lines.

It’s important to consult with a plumbing professional or reference plumbing codes and standards to determine the appropriate size and thickness of PEX pipes for your specific project.

In addition to their flexibility, durability, and cost-effectiveness, PEX pipes also offer several other benefits for plumbing applications:

1. Corrosion-resistant: PEX pipes are resistant to corrosion, which helps prevent leaks and extends the life of your plumbing system.
2. Easy installation: PEX pipes can be easily installed using simple tools and techniques, which can save time and money on installation costs.
3. Reduced noise: PEX pipes have a smooth interior surface that reduces noise from water flowing through the pipes, which can be beneficial in residential and commercial buildings.
4. Energy-efficient: PEX pipes have low thermal conductivity, which helps maintain the temperature of hot water in the pipes and reduces energy loss.
5. Safe for drinking water: PEX pipes are approved by most plumbing codes and standards for use in drinking water applications, making them a safe and reliable choice for residential and commercial plumbing systems.

Overall, PEX pipes offer a wide range of benefits for plumbing applications, including flexibility, durability, cost-effectiveness, and ease of installation. Understanding the different sizes and thicknesses of PEX pipes can help you choose the right pipes for your specific plumbing project, ensuring reliable and efficient performance for years to come.
