Types of PEX Pipes

It is known as the best quality pipe and cost more than other categories.


This PEX pipe is made by the Silane method, also called the moisture method. It is the latest invention of PEX piping.

The pipe is a little bit less flexible than “A”, but costs much lesser. Also, it has a built-in memory coil that helps it get into the original shape after bending.

It is a recommended pipe for residential and water supply usage.

But, it is suitable for short time usage and where you don’t have to bend the pipe but much cheaper than the other types.

By the way, there is another classification of PEX pipe depending on the oxygen barrier. They are two types according to this classification. One is the Oxygen barrier used in the heating system. And the non-Oxigen-barrier PEX pipe used in the hot and cold water supply.
