What is the difference between a Push - fit Copper Tee and a compression copper tee?
Aug 26, 2025
Hey there! As a supplier of Push - fit Copper Tees, I often get asked about the difference between a Push - fit Copper Tee and a compression copper tee. So, I thought I'd break it down for you in this blog post.
Installation Process
Let's start with the installation. This is where the most significant differences between these two types of copper tees become apparent.
Push - fit Copper Tee
The Push - fit Copper Tee is a real time - saver. You don't need any special tools to install it. All you have to do is clean the ends of the pipes that you're going to connect. Then, you simply push the pipe into the fitting. It's as easy as that! The fitting has a rubber O - ring inside. When you push the pipe in, the O - ring creates a tight seal. It's a great option if you're doing a DIY project or if you're on a tight schedule. For example, if you're installing a new plumbing system in a small bathroom, a Push - fit Copper Tee can help you get the job done quickly without a lot of hassle.
Compression Copper Tee
On the other hand, a compression copper tee requires a bit more work. You need to use a special compression tool. First, you have to slide a compression nut and a compression ring onto the pipe. Then, you insert the pipe into the tee fitting. After that, you use the compression tool to tighten the nut onto the fitting. This compresses the ring and creates a seal. It's a more traditional method, but it takes longer. If you're an experienced plumber, you might be used to this method, but for a beginner, it can be a bit tricky.
Sealing Mechanism
The way these two types of tees seal is also quite different.
Push - fit Copper Tee
As I mentioned earlier, the Push - fit Copper Tee uses a rubber O - ring. This O - ring is designed to expand and contract, which helps it create a tight seal even if there's a little bit of movement in the pipes. It's also resistant to water and other fluids, so it can last a long time. However, over time, the O - ring can wear out, especially if it's exposed to high temperatures or harsh chemicals.
Compression Copper Tee
A compression copper tee creates a seal by compressing a metal ring. This metal - to - metal seal is very strong and durable. It can withstand high pressures and temperatures better than a rubber O - ring. But, it's important to make sure that the compression is done correctly. If the nut isn't tightened enough, the seal might leak, and if it's over - tightened, it can damage the fitting.
Cost
Cost is always a factor when you're choosing between different plumbing fittings.
Push - fit Copper Tee
Push - fit copper tees are generally more expensive than compression copper tees. This is because of the technology and materials used in their design. However, when you consider the cost of labor, they can actually be a more cost - effective option. Since they're so easy to install, you can save a lot of time, which means you'll spend less on labor costs.
Compression Copper Tee
Compression copper tees are cheaper upfront. But, as I mentioned, the installation process takes longer, so you might end up spending more on labor. If you're on a tight budget and you have the time and skills to install the fittings yourself, a compression copper tee might be the way to go.
Applications
Both types of tees have their own unique applications.
Push - fit Copper Tee
Push - fit copper tees are great for residential plumbing projects. They're easy to install, so they're perfect for DIYers. They're also suitable for low - pressure systems, such as in a domestic water supply. For example, if you're adding a new faucet to your kitchen sink, a Push - fit Copper Tee can be a great choice.
Compression Copper Tee
Compression copper tees are often used in commercial and industrial applications. Their strong metal - to - metal seal makes them suitable for high - pressure systems. They're also commonly used in systems where the pipes are subject to a lot of movement or vibration. For instance, in a large factory or a commercial building, compression copper tees can provide a reliable connection.
Durability
When it comes to how long these tees will last, there are some differences.


Push - fit Copper Tee
As long as the O - ring is in good condition, a Push - fit Copper Tee can last a long time. But, if the O - ring fails, you'll need to replace the fitting. This can be a bit of a hassle, especially if the fitting is in a hard - to - reach place.
Compression Copper Tee
A compression copper tee is generally more durable. The metal - to - metal seal can withstand a lot of wear and tear. With proper installation and maintenance, it can last for decades.
