PrimoFlex™ Advanced LRT™ Tubing has been designed, formulated, and manufactured for today’s evolving standards in the PC water cooling industry. Advanced LRT™ has been carefully formulated to perform in a wide range of closed loop cooling systems, creating the most compatible water cooling tubing ever created.

LOW RADIUS TECHNOLOGY
PrimoChill’s proprietary blend of notably low durometer PVC and more rigid polymer resin provides PrimoFlex™ Advanced LRT™ with an unbeatable bend ratio and durability. PrimoFlex™ has been tested in exacting laboratory set-ups. This included tests with abrupt small radius bends and multiple directional changes. Advanced LRT™ tubing resisted both twisting and collapse in test results. This allows for tighter bends eliminating kinking that can cause cooling failures and reduction in system performance.

CLARITY IN SIGHT AND MIND
Smooth inner walls improve closed loop sanitation. Advanced LRT™ smooth surface inhibits particulate gathering or entrapment onto the tubing wall. This reduces the potential of bacterial growth and contamination. With this technology, Advanced LRT™ will keep your system looking and feeling as clean as the day it was installed..

Before you install it

This is a component, not an assembly — how it goes in depends on the loop it is joining. What does not change is the last step: leak test before power. Run the pump on a bench supply with the rest of the system unpowered. 24 hours is the standard, an hour is the minimum.

Custom water cooling is installed by you, at your own risk. We are not responsible for leaks, or for damage to your parts or system. If you're unsure at any step, ask before you power the loop.
