Tubing for custom water-cooling loops

PrimoChill PrimoFlex Advanced LRT tubing is made for builders assembling a custom liquid-cooling loop. The 10 ft length of flexible PVC tubing fits 7/16 in ID and 5/8 in OD fittings and uses FDA-approved, phthalate-free material. It ships with SysPrep and Liquid Utopia pre-treatment fluids included.

Low-radius bend performance under sustained pressure

Proprietary low-durometer PVC blended with a rigid polymer resin gives the tube a tight bend ratio that resists kinking and collapse during long-term operation. Smooth inner walls inhibit particulate build-up and bacterial growth, helping the loop stay clean and maintain flow rates over extended use.

Check fitting compatibility and loop layout first

Verify that every compression or barb fitting in your build matches the 7/16 in inner and 5/8 in outer diameters before ordering. Plan the routing to confirm the 10 ft roll provides enough length for all runs, including any tight bends the low-radius design is intended to handle.

Questions about this item

How does the PrimoFlex Advanced LRT tubing handle heat buildup inside a loop that runs all day?

The low-durometer PVC blend resists softening and collapse even after prolonged exposure to typical coolant temperatures, keeping the bore open so flow stays steady.

Which fittings are required to connect the 7/16 in ID by 5/8 in OD tubing?

You need compression or barbed fittings sized for 7/16 inch inner diameter and 5/8 inch outer diameter; the pack includes no fittings.

Will the tubing kink when routed around older rigid-angled fittings or tight CPU blocks?

Low Radius Technology gives a tight bend ratio that resists kinking and twisting around sharp corners and legacy components.
