Flare fittings are essential in various industrial applications’ piping and tubing systems. They are typically used to connect gas or fluid transfer lines, providing a leak-free seal that can withstand high-pressure environments. This post will give an overview of the flare fittings available and their applications.

Types of Flare Fittings

Flared Tubing Fittings

These are the most common type of flare fittings and are used in a wide range of applications. Flared tubing fittings have a tapered thread design that creates a seal as the nut compresses the flared end of the tubing against the fitting body. They are typically made from brass or steel and are used in applications that require medium to high pressure, such as refrigeration, air conditioning, and hydraulic systems.

Flare Hose Fittings

Flare hose fittings are slightly different in design than flared tubing fittings. They utilize a compression fitting secured in place by a threaded nut. Unlike flared tubing fittings, flare hose fittings connect hoses rather than tubing. They are commonly used in fuel lines and brake systems in automotive and industrial applications.

Inverted Flare Fittings

As the name suggests, inverted flare fittings have a reversed flared seat that creates a tight seal by compressing against the fitting nose. They are commonly used in automotive applications, such as brake lines and fuel systems. Inverted flare fittings are typically made from brass or steel and are cost-effective, easy to install, and can withstand high pressures.

Double Flare Fittings

Double flare fittings are similar to flared tubing fittings, but they have a second flare at the end of the tube. This design provides additional strength and rigidity to the tube end, making them ideal for high-pressure applications. Double flare fittings are commonly used in refrigeration and hydraulic systems.

Metric Flare Fittings

Metric flare fittings are designed for use with tubing that has metric dimensions. They use a tapered thread design that creates a seal as the nut compresses the flared end of the tubing against the fitting body. They are commonly used in European automotive and industrial applications and are made from brass or steel.

Conclusion

Flare fittings are essential in many critical applications’ piping and tubing systems. The type of flare fitting to use depends on the specific application and the type of tubing or hose used. It is essential to select the appropriate gush fitting for the intended use to ensure proper installation, avoid leakage, and prevent failure. We hope this guide has provided valuable information about the types of flare fittings available and their applications.
