PEX pipe is a type of flexible plastic tubing commonly used for plumbing and heating systems. It is made from cross-linked polyethylene, which gives it strength and durability. PEX is resistant to scale and chlorine, making it a popular choice for both residential and commercial applications. One of the main advantages of PEX pipe is its ease of installation. It can be bent around corners and does not require joint fittings, reducing the risk of leaks. Additionally, PEX is available in various sizes and colors, allowing for easy identification in plumbing systems.
