How Do Compression Fittings Work and Where are They Used?

Compression fittings are a type of plumbing fitting used to join two pipes or tubes together. They are widely used in both residential and commercial plumbing systems because they are easy to install, relatively inexpensive, and can be reused.

So, how do compression fittings work? The basic principle behind compression fittings is that they use pressure to create a tight seal between the pipes. A compression fitting consists of three main components: the nut, the compression ring (also called a ferrule), and the body or fitting itself.

To install a compression fitting, first, the pipe is cut to the required length and deburred to remove any rough edges. Then, the compression ring is slid onto the end of the pipe, followed by the nut. The pipe is then inserted into the body of the fitting and the nut is tightened onto the body, compressing the ring onto the pipe. This creates a tight seal that prevents leaks.

Compression fittings can be used with a variety of pipe materials, including copper, PVC, and plastic. They are commonly used in applications such as water supply lines, refrigeration systems, and air conditioning systems.

One of the benefits of compression fittings is that they can be easily disassembled and reused if needed. They are also versatile and can be used in a wide range of applications. However, compression fittings are not suitable for high-pressure applications, as they may not provide a strong enough seal.

In conclusion, compression fittings are a reliable and cost-effective way to join pipes in plumbing systems. They are simple to install and can be used with a variety of pipe materials. However, it is important to use them in the appropriate applications to ensure a secure and leak-free connection.
