What is Type L Copper?
Type L copper is a type of copper tube commonly used in residential and commercial plumbing. It is made up of a combination of copper and other elements such as phosphorus and lead, which strengthen the material and make it more resistant to corrosion. Type L copper pipes are known for their medium thickness, which makes them a versatile option for a variety of plumbing applications.
One of the main benefits of using type L copper pipes is their ability to withstand high water pressure. They are also highly durable and can last for decades without needing to be replaced. However, it is important to note that type L copper pipes are not as flexible as other types of pipes, which can make them difficult to install in tight spaces.
What is Type K Copper?
Type K copper is a type of copper pipe that is known for its thickness and durability. It is the thickest of all copper pipe types, with a wall thickness of .049 inches, making it suitable for use in applications that require high pressure levels.
Like type L copper, type K copper is made from high-quality copper alloy. However, type K copper has a higher copper content, which makes it more expensive than type L copper.
Type K copper pipes are commonly used in commercial and industrial applications where high pressure and strength are required. They are also suitable for underground installations and outdoor use due to their thickness and resistance to corrosion.
One of the key benefits of using type K copper pipes is their ability to withstand high pressure, which makes them ideal for applications such as gas lines and fire sprinkler systems. They are also highly durable and have a long lifespan.
However, one of the drawbacks of type K copper is its cost. Due to its thickness and copper content, type K copper pipes are more expensive compared to other types of copper pipes. Additionally, they can be difficult to work with due to their thickness, which can lead to increased labor costs.
Overall, type K copper pipes are a great choice for applications that require high pressure levels and durability. However, their high cost may make them less suitable for smaller-scale projects where lower pressure levels are acceptable.
Differences between Type L Copper and Type K Copper
When choosing between type L copper and type K copper, it is important to understand the differences between the two. Here are the main factors to consider:
| Factor | Type L Copper | Type K Copper |
|---|---|---|
| Durability | Type L copper is more durable compared to type K copper due to its thicker walls. | Type K copper is less durable compared to type L copper due to its thinner walls. |
| Pressure Rating | Type L copper has a lower pressure rating compared to type K copper. | Type K copper has a higher pressure rating compared to type L copper. |
| Flexibility | Type L copper is more flexible compared to type K copper due to its thinner walls. | Type K copper is less flexible compared to type L copper due to its thicker walls. |
| Cost | Type L copper is less expensive compared to type K copper due to its thinner walls. | Type K copper is more expensive compared to type L copper due to its thicker walls. |
Based on these factors, it is recommended to use type L copper for applications that require durability and flexibility, such as residential plumbing and HVAC systems. On the other hand, type K copper is best suited for high-pressure applications found in commercial buildings, underground installations, and areas with high water pressure.
Ultimately, the choice between type L copper and type K copper will depend on the specific needs and requirements of the application.
Applications of Type L Copper
Type L copper pipes are widely used in residential plumbing and heating systems. They are also commonly used in HVAC systems, such as air conditioning and refrigeration.

Type L copper is well suited for applications that require flexibility and durability. Due to its excellent thermal conductivity, it is often used for hot water distribution and radiant heating systems.
Another benefit of Type L copper is its resistance to corrosion. The pipes are less likely to corrode compared to other types of copper pipes, which reduces the risk of leaks. Type L copper tubes are also easy to install and are typically less expensive than other types of copper pipes.
Because of these benefits, Type L copper is a popular choice for residential and light commercial plumbing applications. It is commonly used in potable water systems, as well as for distributing gas and oil.
| Advantages of Type L Copper | Disadvantages of Type L Copper |
|---|---|
| Flexible and easy to install | Prone to kinking and denting |
| Excellent thermal conductivity | Not suitable for high-pressure applications |
| Resistant to corrosion | More expensive than PEX and PVC pipes |
Type L copper is a reliable and versatile option for many plumbing applications. Its combination of flexibility, durability, and corrosion resistance make it a popular choice for residential plumbing and heating systems.
Applications of Type K Copper
Type K copper pipes are commonly used in commercial and industrial settings where high pressures are a concern. These pipes are thicker and have a greater wall thickness than type L. Type K copper pipes are commonly used in underground installations, such as sewer lines and water mains. They are also used in areas where high pressures are a concern, such as in large industrial applications and municipal water systems.
Type K copper pipes are also used in residential plumbing and HVAC systems where high pressures are a concern. These pipes are less flexible than type L copper pipes, but their thicker walls allow them to withstand higher pressures. They can also be used in areas that are subject to freezing temperatures, such as in outdoor water supply lines.
Overall, type K copper pipes are a durable and reliable option for applications where high pressure and strength are required.
Choosing the Right Copper Pipe for Your Needs
With so many factors to consider, choosing the right copper pipe for your needs can be a challenging task. However, understanding the differences between type L copper and type K copper pipes is crucial to making an informed decision.
One of the most important factors to consider is the pressure rating required for your application. Type K copper pipes are thicker and have a higher pressure rating than type L copper pipes, making them ideal for high-pressure applications such as commercial buildings and underground installations.
Another factor to consider is the cost of the pipes. While type K copper pipes are more expensive than type L copper pipes, they are also more durable and have a longer lifespan.
When it comes to residential plumbing and HVAC systems, type L copper pipes are a preferred choice. They are thinner and more flexible than type K copper pipes, making them easier to work with and install. Additionally, they are more cost-effective than type K copper pipes.
In summary, the choice between type L copper and type K copper pipes comes down to specific needs and preferences. If you require high pressure capability and have a larger budget, then type K copper pipes may be the better choice.
