Users confirm this tubing sets the benchmark for performance and durability in custom liquid cooling loops.
Know before you buy
This tubing has an inside diameter (ID) of 7/16" (11 mm) and an outside diameter (OD) of 5/8" (16 mm), with a wall thickness of 1/16" (2 mm).
Yes, this tubing is designed for use with standard water cooling compression fittings that match the 7/16" ID and 5/8" OD specifications. Always ensure your fittings are rated for these specific dimensions to prevent leaks.
PrimoFlex Advanced LRT is specifically formulated to resist the clouding and discoloration often seen in lower-quality PVC tubing. While some minor buildup can occur depending on your coolant choice, it is designed to maintain high clarity for the duration of its service life.
The PVC construction is highly flexible, making it easy to route through complex cooling loops without kinking. It is well-suited for builds that require sharp turns or tight spaces.
This tubing is engineered for wide system compatibility, but it is best paired with high-quality, non-conductive coolants. Avoid using harsh chemical additives that are not specifically designed for PC water cooling, as they may degrade the PVC material over time.
