PrimoFlex Advanced LRT Tubing 10ft Pack

This PrimoFlex Advanced LRT tubing kit supplies 10 feet of flexible PVC hose sized at 7/16 inch inner diameter and 5/8 inch outer diameter. The Brilliant UV Blue colour glows under UV light for custom loop aesthetics. It targets DIY water-cooling builders who want tight bends without kinking.

Low Radius Technology for Tighter Bends

Proprietary Low Radius Technology blends low-durometer PVC with a more rigid polymer resin to deliver an unbeatable bend ratio. Laboratory tests with abrupt small-radius bends and multiple directional changes showed resistance to twisting and collapse. The jump from standard tubing is worth it when routing space is limited and kink-induced flow restriction must be avoided.

Verify Fitting Compatibility and Included Extras

Confirm that your compression or barbed fittings accept 7/16 inch ID and 5/8 inch OD dimensions before ordering. The retail bundle includes Liquid Utopia and SysPrep pre-treatment for system preparation. Smooth inner walls inhibit particulate buildup and bacterial growth for long-term loop cleanliness.

Questions about this item

What inner diameter fittings are required for the 7/16in ID tubing?

Use fittings sized for a 7/16in inner diameter; the tubing has a 5/8in outer diameter and comes in a 10ft length.

How do I use the included SysPrep and Liquid Utopia before installing the tubing?

Flush the loop with SysPrep first, rinse thoroughly, then add Liquid Utopia to the final coolant fill to condition the Advanced LRT material.

How often should the tubing be replaced in a closed-loop system?

The DEHP-free, phthalate-free PVC resists plasticiser leaching and bacterial growth; inspect annually and replace if cloudiness or stiffness appears.
