Tubing meets NSF/ANSI Standard 61 for drinking water. It is made without plasticizers like DEHP, so it won’t impart tastes or odors to the fluid running through it. A lightweight alternative to copper tubing, it connects to fittings with no heat or soldering required. Tubing is opaque, so you cannot see inside the line.

CPVC tubing connects to socket-connect fittings with a CPVC primer and cement (also known as solvent weld). It can handle higher pressures than polyethylene tubing. It is rigid and will not bend. Tubing meets ASTM D2846 specifications and testing requirements for plastic hot- and cold-water distribution systems.

Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
