Tubing dimensions and length

This PrimoChill PrimoFlex Advanced LRT tubing has an inner diameter of 3/8 inch and an outer diameter of 5/8 inch. The pack supplies 10 feet of crystal-clear soft tubing for custom liquid-cooling loops. It is intended for builders assembling a water-cooled PC who need flexible, transparent runs.

Chemical compatibility and included additives

The Advanced LRT formulation is designed to work with a wide range of closed-loop cooling systems and coolant types. A 15 mL bottle of SysPrep loop pre-treatment and a 15 mL bottle of Liquid Utopia additive are included at no extra cost. SysPrep flushes manufacturing debris from blocks, radiators, pumps and reservoirs before the loop is filled.

Fitting and loop preparation checks

Verify that your compression or barbed fittings accept 3/8 inch ID by 5/8 inch OD tubing before ordering. Plan the loop layout so the 10-foot length covers all runs with enough slack for bends. Remember to run the supplied SysPrep cleaning cycle before adding any coolant to the finished loop.

Questions about this item

Should I choose this 10-foot roll or a different length for my loop?

The 10-foot roll provides enough tubing for most single-loop builds with CPU and GPU blocks, leaving a small margin for routing errors or future changes.

What does the 3/8 inch inner diameter mean once the tubing is installed in my system?

A 3/8 inch inner diameter matches standard G1/4 fittings and offers a balance of flow rate and flexibility for typical pump pressures.

How does the soft flexible tubing material affect the bend radius I can achieve?

The Advanced LRT formulation stays pliable at room temperature, allowing tight bends without kinking or the need for heat tools.
