PC water cooling tubing is the highway that liquid travels on to get to the different parts of the water cooling system. It connects all liquid cooling components in your liquid cooled PC. The tubing layout dictates how your coolant travels through your water pump, water blocks, radiators and reservoir. Your choice of tubing will decide what type of water cooling fittings you will need, as well as any tools or accessories you may need in working with it. Things to consider in choosing PC water cooling tubing are length, diameter, and whether you want rigid tubing or flexible tubing. TITAN RIG carries rigid tubing and flexible tubing in a variety of sizes and materials as well as all the tools and accessories needed to make perfect tubing runs in your PC.
