Tube compression fittings are a type of fitting that can be used to connect tubing or piping together. They are popular because they are easy to use and offer a strong, leak-free connection.
This article will discuss what compression fittings are, how they work, and when they should be used. We will also provide instructions on how to install compression fittings.
What are tube compression fittings, and what do they do
Tube compression fittings are used to join two pieces of tube together. The fitting consists of a short length of tube with a threaded end that is inserted into the end of the other piece of pipe.
A compression nut and compression ring (ferrule) is threaded onto the tube’s end and tightened. This pulls the two pieces of pipe together and creates a seal. Compression fittings are typically used on copper, stainless steel, and plastic tubing.
Compression fittings come in various materials, including brass, stainless steel, plastic, and Teflon. They are available in many variations like unions, tee’s, elbows, etc.
How do tube compression fittings work
Tube compression fittings are used to connect two pieces of tubing together, typically in a hydraulic or pneumatic system. The tube is inserted into the fitting, and then the nut is tightened, compressing the tube and creating a secure connection.
In some cases, a ferrule is also used with the tube and nut to create an even more secure seal.
Tube compression fittings are recommended for applications where vibration or thermal expansion might cause other types of fittings to loosen or leak. They are also well-suited for applications where quick disconnection is desired.
When properly installed, tube compression fittings provide a reliable, leak-free connection that can withstand significant pressure.
Types of tube compression fittings
There are many different types of tube compression fittings available on the market today. Each type has its unique benefits and drawbacks, so it is essential to choose the correct fitting for your specific needs. Some of the most common types of tube compression fittings include:
– SAE (JIC) fittings: These fittings are commonly used in hydraulic systems. They have a 37-degree flare on the end of the tube, which helps to create a secure connection.
– BSPP fittings: These fittings are often used in air and gas lines. They have a tapered external thread that helps create a seal when it is screwed into place.
– NPT fittings: These fittings are commonly used in plumbing applications. They have a tapered internal thread that helps create a seal when it is screwed into place.
– Flareless tube compression fittings: These fittings do not require the use of a tube flaring tool. They have an internal sleeve that helps create a seal when it is tightened in place.
Tube compression fittings are different from push-lock fittings because they have nut and ferrules to connect to your piece of tubing while the push-lock fittings do not have separate parts.
Advantages of tube compression fittings
There are many advantages to using tube compression fittings. First, they provide a leak-proof connection that is perfect for high-pressure applications.
Second, they are straightforward to install and require no special tools or training.
Third, they are highly versatile and can be used with various tubing materials.
Finally, tube compression fittings are solid and durable and can withstand high temperatures and pressures. As a result, they are an excellent choice for various applications.
Disadvantages of compression fittings
While tube compression fittings have many advantages, there are also some disadvantages to consider. One downside is that they can be difficult to remove once installed. This can be an issue if you need to make future repairs or changes to your plumbing.
Additionally, tube compression fittings are not as forgiving as other fittings if you make a mistake during installation. If you do not get the perfect seal, you may experience leaks. Finally, tube compression fittings can be more expensive than other fittings.
While they are typically easy to install and provide a reliable seal, you may consider other options if cost is a significant consideration.
When to use tube compression fittings
Tube compression fittings are a type of plumbing fitting used to connect two pieces of tubing or hosing. They are most commonly used in applications where a water-tight seal is required, such as in air or vacuum systems.
Tube compression fittings consist of a body, a nut, and a ferrule. The body is the portion of the fitting that is visible when installed. The nut is threaded onto the body and tightened to secure the tube in place. The ferrule is a small ring that fits over the end of the tube and helps to create a tight seal.
When selecting tube compression fittings, it is vital to consider the size and type of tubing that will be used. Tube compression fittings are available in a variety of sizes, and the right size must be selected for the tube that will be used.
In addition, tube compression fittings are available in many different variations. The type of tube compression fitting required will depend on the specific application.
How to install tube compression fittings?
Tube compression fittings are used to connect two pieces of tubing together, typically in a plumbing or hydraulic application. To properly install tube compression fittings, follow these steps:
1. Cut the tubing to the desired length, making sure that both ends are cut squarely.
2. Slide the tube nut onto the tubing, followed by the tube sleeve (ferrule).
3. Insert the tubing into the tube fitting until it bottoms out.
4. Tighten the tube nut until it is snug against the tube sleeve. DO NOT overtighten.
5. Repeat for all connections.
If installed correctly, tube compression fittings provide a secure, leak-free connection. Follow the manufacturer’s instructions carefully to avoid damage to the fittings or tubing.
