Why are compression fittings used in plumbing?
Compression fittings are commonly used in plumbing systems to connect two pipes together. These fittings work by compressing a ferrule, which is a small circular component, onto the end of a pipe. The compression of the ferrule creates a tight seal, preventing water from leaking out.
There are several reasons why compression fittings are a popular choice in plumbing:
Versatility: Compression fittings can be used with a wide variety of pipes, including copper, brass, and plastic. This makes them a versatile choice for plumbing systems that may need to be connected to pipes made from different materials.
Easy installation: Compression fittings are relatively easy to install, even for those who are not experienced in plumbing. Simply insert the pipe into the fitting and tighten the compression nut to secure it in place.
Ease of maintenance: In the event of a leak, compression fittings can be easily removed and replaced without having to disconnect any other parts of the plumbing system.
Durability: Compression fittings are made of brass or other corrosion-resistant materials, making them long-lasting and able to withstand high water pressure and temperatures.
Cost-effective: Compression fittings are generally less expensive than other types of plumbing fittings, making them a cost-effective choice for plumbing projects.
However, it is important to note that compression fittings are not appropriate for all plumbing applications. For example, they are not recommended for use in areas where there is frequent freezing and thawing, as the movement can cause the fitting to loosen and leak.
To install a compression fitting, follow these steps:
Cut the pipe: Using a pipe cutter, cut the pipe to the correct length for the fitting. Ensure that the cut end is clean and square.
Insert the ferrule: Slide the ferrule onto the end of the pipe, making sure that it is centered.
Insert the pipe into the fitting: Insert the pipe into the compression fitting, making sure that the ferrule is between the fitting and the pipe.
Tighten the compression nut: Using a wrench, tighten the compression nut onto the fitting, compressing the ferrule onto the pipe and creating a tight seal.
Test the fitting: Turn on the water supply and check for leaks. If there are any leaks, tighten the compression nut a little more.
In conclusion, compression fittings are a popular choice for plumbing systems due to their versatility, ease of installation, ease of maintenance, durability, and cost-effectiveness. However, it is important to choose the right type of fitting for the specific plumbing application and to install it correctly to ensure a leak-free system.
