PEX cold expansion fittings are a popular type of fitting used in plumbing systems. But what are they, and how do they work?
What Are PEX Cold Expansion Fittings?
PEX cold expansion fittings are used to connect PEX pipes in plumbing systems. They are made of brass and have a barb on one end that is inserted into the PEX pipe. The other end of the fitting has a threaded connection that can be attached to other plumbing components. The fitting is then secured to the pipe using a cold expansion tool that compresses the fitting and the pipe together, creating a secure and leak-proof connection.
Benefits of PEX Cold Expansion Fittings
There are several benefits to using PEX cold expansion fittings in plumbing systems. First, they provide a secure and leak-proof connection that is resistant to corrosion and chemicals. This makes them ideal for use in harsh environments, such as in industrial settings or in areas with hard water. Additionally, PEX cold expansion fittings are easy to install and require no soldering or glue, making them a cost-effective choice for plumbers and homeowners alike.
How Do PEX Cold Expansion Fittings Work?
PEX cold expansion fittings work by compressing the fitting and the PEX pipe together using a cold expansion tool. The tool stretches the pipe slightly, making it larger than the fitting. The fitting is then inserted into the pipe and the tool is used to compress the fitting and the pipe together. This creates a secure and leak-proof connection that can withstand high pressures and temperatures.
In conclusion, PEX cold expansion fittings are a popular choice in plumbing systems due to their reliability, durability, and ease of installation. They provide a secure and leak-proof connection that is resistant to corrosion and chemicals, making them ideal for use in harsh environments. When choosing PEX cold expansion fittings, consider factors such as the size and pressure requirements of your plumbing system, as well as the compatibility of the fitting with other plumbing components. With proper installation and maintenance, PEX cold expansion fittings can provide many years of reliable service.
