CPVC CTS Pipe

Copper Tube Size (CTS) CPVC Pipe

CPVC CTS, or Copper Tube Size CPVC pipe is used for hot and cold water distribution. CPVC CTS is used for pressure systems that will not exceed 180 degrees Fahrenheit. The sizing system for this type of pipe is different from standard PVC parts, so they cannot be used together. CTS pipe should always be used with CTS fittings. Our line of CTS CPVC pipe and fittings is easy to recognize by its tan, almost yellow color. Our pipe is sold in 5 foot lengths for easy shipping.

An Option for Hot & Cold Applications

CPVC has long been lauded for its ability to handle both hot and cold water distribution really well. Unlike other plastics, CPVC can handle water service up to 180 degrees Fahrenheit. This is much higher than other materials like standard PVC which has a maximum temperature that is 20 degrees lower.

An Energy Efficient Option

Our CTS CPVC piping systems have better heat retention than comparable metal pipe. That means it takes less energy to keep water hot, and lower water heating costs for your home or business. Plastic piping can also be insulated using foam sheaths for even better heat retention and to help protect pipes from freezing temperatures.

Chlorinated Poly Vinyl Chloride: The Material

Known as CPVC for short, Chlorinated Poly Vinyl Chloride is a versatile and durable material. As a pipe, it provides excellent corrosion and chemical resistance, which is handy in residential and industrial uses alike. Similar to PVC, CPVC is also a plastic material, but the chemical makeup is different. Because of this, CPVC has different properties than PVC, like its ability handle higher temperatures without degradation. Like PVC and similar plastics, CPVC is lightweight, so it is easy to ship, carry, and install. It is also a cost-efficient option as opposed to copper pipe.

Copper Tube Sizing

Unlike standard PVC pipe, CTS CPVC pipe uses the Copper Tube Size sizing system. That means a PVC pipe called 2 inch size, will measure differently that a CTS CPVC pipe called 2 inch size. The CTS system is universal across all CTS CPVC parts though, so a 2 inch CTS pipe will fit a 2” CTS fitting. This sizing system is common in many residential applications, like hot water heater connections. Unlike PVC, CTS CPVC is only available in a limited number of sizes. Generally, it is only used for applications up to 2 inch in size.

Installing CTS CPVC Pipe

CPVC pipe and fittings should be installed using CPVC solvent cement for all socket weld type fittings, and threaded together with PTFE tape or a thread sealant for all threaded type fittings.

Solvent weld connections are made by applying primer and then specially formulated CPVC solvent cement to the outside of the pipe end and the inside of the socket fitting. The two are then pressed together and held in place for about 30 seconds to secure the joint. Once installed, this is a permanent joint and cannot be taken apart after installation, providing a durable and long-lasting connection.
