Is PEX CTS?

/ By

PEX (cross-linked polyethylene) is commonly used in plumbing systems for water distribution. CTS stands for “copper tube size” and refers to a standard sizing system used in the plumbing industry for both copper and plastic pipes. PEX can be classified as CTS or non-CTS based on its sizing.

  • PEX-CTS: PEX tubing that adheres to the copper tube size standard. This means it has the same outside diameter as traditional copper pipes of the corresponding size. PEX-CTS is typically used with compression or push-fit fittings specifically designed for CTS pipes.

  • PEX non-CTS: PEX tubing with a larger outside diameter than copper pipes. Non-CTS PEX requires specific fittings designed for PEX, such as crimp or clamp fittings.

In summary, PEX can be CTS or non-CTS depending on its sizing, and the choice of fittings should match the type of PEX being used.
