Flared Tube Sleeves for 37° Flared Tube Fittings

Flared Tube Sleeves

Flared tube sleeves, also known as tube flaring sleeves or compression sleeves, are essential components in various mechanical and plumbing applications. They are commonly used to create secure connections between tubes or pipes, ensuring leak-free and reliable joints.The primary purpose of flared tube sleeves is to provide a tight seal between the tube and the fitting to prevent leakage of fluids or gases. These sleeves typically consist of a cylindrical metal piece with a flared end. The flared end is designed to match the shape of the fitting or connector it is being used with.The process of using flared tube sleeves involves inserting the sleeve onto the end of the tube before it is connected to the fitting. The tube is then flared using a specialized flaring tool, which expands the end of the tube outward to create a wider surface area. This flared end allows for a better seal when the tube is secured to the fitting.Once the tube is flared, it is inserted into the fitting, and the flared end is compressed against a tapered seat within the fitting using a nut or a fitting assembly tool. The compression forces the sleeve to tightly grip the tube, creating a secure connection. This compression action also forms a tight seal between the sleeve, tube, and fitting, minimizing the risk of leaks.Flared tube sleeves are commonly used in applications such as plumbing systems, hydraulic systems, refrigeration systems, and automotive brake lines. They are especially useful in situations where high-pressure or high-vibration conditions are present, as they provide a robust and reliable connection.

How Do Flared Tube Sleeves Work?

Flared tube sleeves work by creating a tight seal between the flared tubing and the male fitting. The sleeve is a ring-shaped piece of metal that is placed over the flared tubing before the nut is tightened. When the nut is tightened, it compresses the sleeve, which in turn compresses the flared tubing against the male fitting. This creates a metal-to-metal seal that is highly resistant to pressure and vibration.

Flared tube sleeves are typically made of brass or copper, and they are available in a variety of sizes to fit different tubing diameters. They are also available in different flare angles, such as 37° and 45°. The flare angle must match the angle of the male fitting in order to create a proper seal.

Flared tube sleeves are used in a variety of applications, including hydraulic systems, fuel systems, and air conditioning systems. They are also used in industrial applications such as machine tools and robotics. Flared tube sleeves are known for their reliability and durability, and they are often used in applications where high pressure and vibration are present.

Here is a more detailed explanation of how flared tube sleeves work:

1. The tubing is flared using a flaring tool. This creates a tapered end on the tubing that is slightly larger than the inside diameter of the male fitting.
2. The sleeve is placed over the flared tubing.
3. The nut is tightened over the sleeve.
4. As the nut is tightened, it compresses the sleeve, which in turn compresses the flared tubing against the male fitting.
5. This creates a metal-to-metal seal that is highly resistant to pressure and vibration.

Flared tube sleeves are a critical component in many applications, and they play an important role in ensuring the safe and reliable operation of equipment.
