Flare Nut

Flare Nut

A flare nut is a type of fastener used to connect two pieces of pipe or tubing. It is a threaded fitting with a flared end that is designed to create a seal when tightened. Flare nuts are commonly used in automotive applications, such as for connecting brake lines and fuel lines.

Flare nuts are available in a variety of sizes and materials. The most common material is brass, but they can also be made from steel, stainless steel, and aluminum. Flare nuts are typically sized by their internal diameter, which is the same as the diameter of the pipe or tubing they are used to connect.

Flare nuts are installed by first threading them onto the pipe or tubing. The nut is then flared using a flaring tool, which creates a series of folds in the end of the pipe or tubing. These folds create a seal that prevents leaks.

Flare nuts are a reliable and easy-to-use type of fastener. They are also relatively inexpensive, making them a popular choice for automotive applications.

Types of Flare Nuts

There are two main types of flare nuts:

• Straight flare nuts have a straight edge on the flared end. They are typically used for applications where the pipe or tubing is not under a lot of pressure.
• Angled flare nuts have a chamfered edge on the flared end. They are typically used for applications where the pipe or tubing is under a lot of pressure.

Flare nuts can also be classified by their thread pitch. The thread pitch is the number of threads per inch on the nut. The most common thread pitch for flare nuts is 1/8-27.

Benefits of Flare Nuts

Flare nuts offer a number of benefits over other types of fasteners, including:

• A tight seal: The flared end of a flare nut creates a tight seal that prevents leaks.
• Easy to install: Flare nuts are easy to install with a flaring tool.
• Reliable: Flare nuts are a reliable type of fastener that can withstand a lot of pressure.
• Inexpensive: Flare nuts are relatively inexpensive, making them a good option for budget-minded projects.

Conclusion

Flare nuts are a versatile and reliable type of fastener that is commonly used in automotive applications. They are available in a variety of sizes and materials, and can be installed easily with a flaring tool.
